# SharePoint Component

The SharePoint component makes it easy to upload, download, and manage files and folder within SharePoint sites and document libraries.

## Syntax

```text
nsoftware.CloudStorage.SharePoint
```

## Remarks

The SharePoint component provides a simple interface to working with a SharePoint site document libraries. Capabilities include uploading and downloading files, strong encryption support, creating folders, moving and copying resources, listing SharePoint sites, and more.

To begin, first create an account and register your application with the Microsoft Graph API. Consult the Microsoft Graph API documentation for instructions on this process.

## Authentication

This component requires authentication via OAuth 2.0. First, perform OAuth authentication using the [OAuth](#oauth-property-sharepoint-component) property to set the appropriate fields for the chosen [ClientProfile](#OAuthSettings_f_ClientProfile) and [GrantType](#OAuthSettings_f_GrantType).

The component has the following default [ServerAuthURL](#OAuthSettings_f_ServerAuthURL) and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) fields. Additionally, below is a common scope for the component:

|  |  |
| --- | --- |
| Authorization Server URL | "https://login.microsoftonline.com/common/oauth2/v2.0/authorize" |
| Token Server URL | "https://login.microsoftonline.com/common/oauth2/v2.0/token" |
| Scopes | "offline_access files.readwrite files.readwrite.all sites.readwrite.all" |

Additionally, depending on how the application is registered (e.g. Multi-tenant) and what [GrantType](#OAuthSettings_f_GrantType) is selected (e.g. Client Credentials and Password), it may be required to use the tenant ID rather than "common" in the [ServerAuthURL](#OAuthSettings_f_ServerAuthURL) and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) fields. In the case of Client Credentials and Password grant types, it is also required to use the "default" scopes of the app registration. See below for examples of the modified URLs and scopes:

|  |  |
| --- | --- |
| Authorization Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/authorize" |
| Token Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/token" |
| Scopes | "https://graph.microsoft.com/.default" |

Below is a brief description of the different [ClientProfile](#OAuthSettings_f_ClientProfile) and [GrantType](#OAuthSettings_f_GrantType) values that are supported by this component. For a more in-depth description of what needs to be set, refer to the service documentation.

### Application Profile

This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the component. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.

To start the authentication and authorization process, the [Authorize](#authorize-method-sharepoint-component) method should be called. If the authorization and authentication was successful, then the [AccessToken](#OAuthSettings_f_AccessToken) field will be populated. Additionally, if a *refresh token* was provided the [RefreshToken](#OAuthSettings_f_RefreshToken) field will be populated as well. These values of the fields are for informational purposes. The component will also cache these tokens along with when the [AccessToken](#OAuthSettings_f_AccessToken) will be expired. When a method that makes requests to the service provider is called or the [Authorize](#authorize-method-sharepoint-component) method is called the component will automatically check to see if the *access token* is expired. If it is, it will then automatically try to get a new [AccessToken](#OAuthSettings_f_AccessToken). If the [Authorize](#authorize-method-sharepoint-component) method was not used and user interaction would be required, the component will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the [GrantType](#OAuthSettings_f_GrantType) field. To force the component to only check the *access token* when the [Authorize](#authorize-method-sharepoint-component) method is called, the [OAuthAutomaticRefresh](#OAuthAutomaticRefresh) configuration setting can be set to false.

A brief description of the supported values for the [GrantType](#OAuthSettings_f_GrantType) field are below. For more information, see the service documentation.

**Authorization Code**

When using the *Authorization Code* grant type, the component will use an *authorization code* to get an *access token*. For this [GrantType](#OAuthSettings_f_GrantType) the component expects a [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), [ServerAuthURL](#OAuthSettings_f_ServerAuthURL), and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) to be set. When the [Authorize](#authorize-method-sharepoint-component) method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the component will parse the *authorization code*, setting the [AuthorizationCode](#OAuthSettings_f_AuthorizationCode) field, from the redirect. Immediately, the component will make a request to the token server to exchange the *authorization code* for an *access token*. The token server will return an *access token* and possibly a *refresh token*. If the [RefreshToken](#OAuthSettings_f_RefreshToken) field is set, or a *refresh token* is cached, then the component will not launch the browser and use the *refresh token* in its request to the token server instead of an *authorization code*.

**Example: **

```csharp
Sharepoint sharepoint = new Sharepoint();

sharepoint.OAuth.ClientProfile = CloudOAuthClientProfiles.cocpApplication;
sharepoint.OAuth.GrantType = OAuthSettingsGrantTypes.cogtAuthorizationCode;
sharepoint.OAuth.ClientId = CLIENT_ID;
sharepoint.OAuth.ClientSecret = CLIENT_SECRET;
sharepoint.OAuth.AuthorizationScope = "offline_access files.readwrite files.readwrite.all";

sharepoint.Authorize();
```

**Client Credentials**

When using the *Client Credentials* grant type, the component will act as a service instead of authorizing and authenticating as a user. This allows for the component to avoid user interaction. This is typically used when running in an application that can not have user access. This grant type requires additional set up to be done in the service providers portal before it can be used. For this [GrantType](#OAuthSettings_f_GrantType) the component expects a [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) to be set. When the [Authorize](#authorize-method-sharepoint-component) method is called, the component will make a request to the token server for an *access token*. The token server will return an *access token* if the application has the authorization to do so. When this *access token* is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.

**Implicit**

Note: This grant type is considered insecure and should only be used when necessary.

When using the *Implicit* grant type, the component will request the authorization server to get an *access token*. For this [GrantType](#OAuthSettings_f_GrantType) the component expects a [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), and [ServerAuthURL](#OAuthSettings_f_ServerAuthURL) to be set. When the [Authorize](#authorize-method-sharepoint-component) method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the component will parse the *access token* from the redirect.

A disadvantage of the grant type is that can not use a *refresh token* to silently get a new *access token*. Most service providers offer a way to silently get a new *access token*. See the service documentation for specifics. This means the component will not be able to automatically get a fresh token once it expires.

**Password**

Note: This grant type is considered insecure and should only be used when necessary.

When using the *Resource Owner Password Credentials* grant type, the component will authenticate as the resource owner. This allows for the component to avoid user interaction. This grant type often has specific limitations put on it by the service provider. See the service documentation for more details.

For this [GrantType](#OAuthSettings_f_GrantType) the component requires [OAuthPasswordGrantUsername](#OAuthPasswordGrantUsername), [ClientSecret](#OAuthSettings_f_ClientSecret), and [ServerTokenURL](#OAuthSettings_f_ServerTokenURL) to be set. The [ClientSecret](#OAuthSettings_f_ClientSecret) should be set to the password of the account instead of a typical secret. In some cases, the [ClientId](#OAuthSettings_f_ClientId) also needs to be set. When the [Authorize](#authorize-method-sharepoint-component) method is called, the component will make a request to the token server for an *access token* using the username and password. The token server will return an *access token* if the authentication was successful. When this *access token* is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.

### Web Profile

 This profile is similar to setting the component to the Application profile and Authorization Code grant type except the component will not launch the browser. It is typically used in situations where there is a back-end that is supporting some front end. This profile expects that [ClientId](#OAuthSettings_f_ClientId), [ClientSecret](#OAuthSettings_f_ClientSecret), [ServerAuthURL](#OAuthSettings_f_ServerAuthURL), [ServerTokenURL](#OAuthSettings_f_ServerTokenURL), and the [ReturnURL](#OAuthSettings_f_ReturnURL) fields to be set. Before calling the [Authorize](#authorize-method-sharepoint-component) method, the [WebAuthURL](#OAuthSettings_f_WebAuthURL) field should be queried to get a URL. This URL should be used to redirect the user to the authorization page for the service provider. The *redirect_uri* parameter of this URL is mapped to the [ReturnURL](#OAuthSettings_f_ReturnURL) field. The [ReturnURL](#OAuthSettings_f_ReturnURL) field should be set to some web server that will parse the *authorization code* out of the query parameter from the redirect. Once the *authorization code* is parsed, it should be passed back to the server where it is then set to the [AuthorizationCode](#OAuthSettings_f_AuthorizationCode) field. Once that is set, the [Authorize](#authorize-method-sharepoint-component) method can be called to exchange the *authorization code* for an *access token* and *refresh token* if provided. The component will then cache these values like normal and use them to make requests. If the [RefreshToken](#OAuthSettings_f_RefreshToken) field is set, or a *refresh token* is cached, then the [Authorize](#authorize-method-sharepoint-component) method can immediately be called to make a request to the token server to get a new *access token*.

### External OAuth Support

 For complex profiles or grant types, or for more control of the flow, it is possible to perform OAuth authentication using a separate OAuth client. Once complete you should have an authorization string which looks like:

```text
Bearer ACCESS_TOKEN_VALUE
```

Assign this value to the [Authorization](#authorization-property-sharepoint-component) property before attempting any operations. Setting the [Authorization](#authorization-property-sharepoint-component) property will cause the component to ignore the values set in the [OAuth](#oauth-property-sharepoint-component) property.

 For Example:

```csharp
Oauth oauth = new Oauth();

oauth.ClientId = "CLIENT_ID";
oauth.ClientSecret = "CLIENT_SECRET;
oauth.ServerAuthURL = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize";
oauth.ServerTokenURL = "https://login.microsoftonline.com/common/oauth2/v2.0/token";
oauth.AuthorizationScope = "offline_access files.readwrite files.readwrite.all sites.readwrite.all";
oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode;

sharepoint.Authorization = oauth.GetAuthorization();
```

 Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

NOTE: There are a couple of extra factors to consider when doing OAuth for SharePoint; please refer to the [Authorization](#authorization-property-sharepoint-component) property documentation for more information.

## Listing Resources

[ListResources](#listresources-method-sharepoint-component) lists resources within the folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). Calling this method will fire the [ResourceList](#resourcelist-event-sharepoint-component) event once for each resource, and will also populate the [Resources](#resources-property-sharepoint-component) collection.

If there are still more resources available to list when this method returns, the [ResourceMarker](#resourcemarker-property-sharepoint-component) property will be populated. Continue to call this method until [ResourceMarker](#resourcemarker-property-sharepoint-component) is empty to accumulate all pages of results in the [Resources](#resources-property-sharepoint-component) collection. Alternatively, the [AccumulatePages](#AccumulatePages) configuration setting can be disabled to clear the [Resources](#resources-property-sharepoint-component) collection every time a page of results is returned.

```text
// ResourceList event handler.
sharepoint.OnResourceList += (s, e) => {
  Console.WriteLine(e.Name);
};

// (Assume that the RemoteId property isn't set; it takes precedence if it is.)
sharepoint.RemotePath = "/work_files/serious_business/cats";
do {
  sharepoint.ListResources();
} while (!string.IsNullOrEmpty(sharepoint.ResourceMarker));

for (int i = 0; i < sharepoint.Resources.Count; i++) {
  // Process resources here.
}
```

## Downloading Files

The [DownloadFile](#downloadfile-method-sharepoint-component) method downloads the file resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component).

If a stream has been specified using [SetDownloadStream](#setdownloadstream-method-sharepoint-component), the file data will be sent through it. If a stream is not specified, and [LocalFile](#localfile-property-sharepoint-component) is set, the file will be saved to the specified location; otherwise, the file data will be held by [ResourceData](#resourcedata-property-sharepoint-component).

To download and decrypt an encrypted file, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharepoint-component) and [EncryptionPassword](#encryptionpassword-property-sharepoint-component) before calling this method.

### Download Notes

In the simplest use-case, downloading a file looks like this:

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.RemoteId = sharepoint.Resources[0].Id;
sharepoint.DownloadFile();
```

**Resuming Downloads**

The component also supports resuming failed downloads by using the [StartByte](#startbyte-property-sharepoint-component) property. If a download is interrupted, set [StartByte](#startbyte-property-sharepoint-component) to the appropriate offset before calling this method to resume the download.

```text
string downloadFile = "../MyFile.zip";
sharepoint.LocalFile = downloadFile;
sharepoint.RemoteId = sharepoint.Resources[0].Id;
sharepoint.DownloadFile();

//The transfer is interrupted and DownloadFile() above fails. Later, resume the download:

//Get the size of the partially downloaded file
sharepoint.StartByte = new FileInfo(downloadFile).Length;
sharepoint.DownloadFile();
```

**Resuming Encrypted File Downloads**

Resuming encrypted file downloads is only supported when [LocalFile](#localfile-property-sharepoint-component) was set in the initial download attempt.

If [LocalFile](#localfile-property-sharepoint-component) is set when beginning an encrypted download, the component creates a temporary file in [TempPath](#TempPath) to hold the encrypted data until the download is complete. If the download is interrupted, [DownloadTempFile](#DownloadTempFile) will be populated with the path of the temporary file that holds the partial data.

To resume, [DownloadTempFile](#DownloadTempFile) must be populated, along with [StartByte](#startbyte-property-sharepoint-component), to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to [LocalFile](#localfile-property-sharepoint-component).

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.EncryptionPassword = "password";
sharepoint.RemoteId = sharepoint.Resources[0].Id;
sharepoint.DownloadFile();

//The transfer is interrupted and DownloadFile() above fails. Later, resume the download:

//Get the size of the partially download temp file
sharepoint.StartByte = new FileInfo(sharepoint.Config("DownloadTempFile")).Length;
sharepoint.DownloadFile();
```

## Uploading Files

The [UploadFile](#uploadfile-method-sharepoint-component) method uploads new file resources to the folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component).

If [SetUploadStream](#setuploadstream-method-sharepoint-component) has been used to set an upload stream, it will take priority as the file data source. If [LocalFile](#localfile-property-sharepoint-component) is set the file will be uploaded from the specified path. If [LocalFile](#localfile-property-sharepoint-component) is not set the data in [ResourceData](#resourcedata-property-sharepoint-component) will be used.

To encrypt the file before uploading it, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharepoint-component) and [EncryptionPassword](#encryptionpassword-property-sharepoint-component).

### Upload Notes

SharePoint offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

**Simple**

By default the component uses the simple upload mechanism.

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.UploadFile("MyFile.zip");
```

**Resumable**

To enable resumable uploads set [UseResumableUpload](#useresumableupload-property-sharepoint-component) to *true*. This is recommended for large files. The component will automatically fragment the specified file into smaller pieces and upload each individually. [FragmentSize](#FragmentSize) may be set to specify the size of the fragment if desired. The default fragment size is 10 MB.

When [UseResumableUpload](#useresumableupload-property-sharepoint-component) is set to *true* and [UploadFile](#uploadfile-method-sharepoint-component) is called, a resumable upload session is started by the component. [ResumeURL](#resumeurl-property-sharepoint-component) is populated with a URL identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the [FragmentComplete](#fragmentcomplete-event-sharepoint-component) event fires after each fragment is uploaded to indicate overall progress. The component also updates [StartByte](#startbyte-property-sharepoint-component) as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that [ResumeURL](#resumeurl-property-sharepoint-component) and [StartByte](#startbyte-property-sharepoint-component) are populated (if the same instance of the component is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call [UploadFile](#uploadfile-method-sharepoint-component) again to resume the upload at the specified [StartByte](#startbyte-property-sharepoint-component) offset.

Note that if the upload is not resumed after some time the upload session will expire. [PollUploadStatus](#polluploadstatus-method-sharepoint-component) may be used to check the status of a resumable upload, including when it will expire (which is stored in the [UploadExpDate](#UploadExpDate) configuration setting). An interrupted upload can be aborted explicitly using the [AbortUpload](#abortupload-method-sharepoint-component) method.

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.UploadFile("MyFile.zip");

//The transfer is interrupted and UploadFile() above fails. Later, resume the download.
//Using the same instance StartByte and ResumeURL are already populated from the previous
//upload attempt.
sharepoint.UploadFile("MyFile.zip");
```

```text
MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip"));
sharepoint.SetUploadStream(uploadStream);
sharepoint.UploadFile("MyFile.zip");

//The transfer is interrupted and UploadFile() above fails. Later, resume the download.
//Using the same instance StartByte and ResumeURL are already populated from the previous
//upload attempt.
//You MUST reset the stream's position to where it was when you first started the upload!
uploadStream.Position = 0;
sharepoint.UploadFile("MyFile.zip");
```

## Additional Functionality

The SharePoint component offers advanced functionality beyond simple uploads and downloads. For instance:

- Encrypt and decrypt files using the [EncryptionAlgorithm](#encryptionalgorithm-property-sharepoint-component) and [EncryptionPassword](#encryptionpassword-property-sharepoint-component) properties.
- Basic file and folder manipulation and organization using methods such as [CopyResource](#copyresource-method-sharepoint-component), [CreateFolder](#createfolder-method-sharepoint-component), [DeleteResource](#deleteresource-method-sharepoint-component), [MoveResource](#moveresource-method-sharepoint-component), and [UpdateResource](#updateresource-method-sharepoint-component).
- Creation of resource sharing links using [CreateLink](#createlink-method-sharepoint-component).
- Change tracking with [ListChanges](#listchanges-method-sharepoint-component).
- Advanced resource listing using the [Search](#search-method-sharepoint-component) method.
- Listing, getting, and selecting a document libraries using the [ListDocumentLibraries](#listdocumentlibraries-method-sharepoint-component) and [GetDocumentLibraryInfo](#getdocumentlibraryinfo-method-sharepoint-component) methods and the [DocumentLibrary](#documentlibrary-property-sharepoint-component) property.
- Listing the current SharePoint sites available to the authenticated entity with the [ListSites](#listsites-method-sharepoint-component) method.
- And more!

# Authorization Property ([SharePoint](#sharepoint-component) Component)

OAuth 2.0 Authorization Token

## Syntax

```text
public string Authorization { get; set; }
```

## Default Value

""

## Remarks

This component supports authentication via OAuth 2.0. First, perform OAuth authentication using the [OAuth](#oauth-property-sharepoint-component) property or a separate OAuth client. If using the [OAuth](#oauth-property-sharepoint-component) property, then the Authorization property will not be used. Once complete you should have an authorization string which looks like:

```text
Bearer ACCESS_TOKEN
```

 Assign this value to the Authorization property before attempting any operations.

### Authorization Notes

 Microsoft's OAuth system is heavily integrated into Azure Active Directory, which has undergone a number of restructurings in recent years. The task of registering an application for use with Microsoft Graph (or any other Microsoft service that supports OAuth authentication) is a common point of confusion, especially given the continued availability of old documentation about Azure AD.

At this time, the most straightforward instructions available for registering an application for use with Microsoft Graph can be found on [Register your app](https://docs.microsoft.com/en-us/graph/auth-register-app-v2) page of the Microsoft Graph API documentation. One of the steps on that page is selecting the application's *supported account types*. In most cases, the "Accounts in any organizational directory and personal Microsoft accounts" option is the most appropriate.

Once the application is registered, refer to the instructions on the [Get access on behalf of a user](https://docs.microsoft.com/en-us/graph/auth-v2-user) page of the Microsoft Graph API documentation for information about what endpoints to use with the [OAuth](#oauth-property-sharepoint-component) property for authentication. Pay special attention to the description of the possible value for the *{tenant}* segment of the OAuth endpoints.

Refer to the Microsoft Graph API's [permissions documentation](https://docs.microsoft.com/en-us/graph/permissions-reference) for more information about the OAuth scopes that Microsoft Graph supports.

## Syntax

```text
public bool Idle { get; }
```

## Default Value

True

## Remarks

This property will be False if the component is currently busy (communicating or waiting for an answer), and True at all other times.

This property is read-only.

# LocalFile Property ([SharePoint](#sharepoint-component) Component)

The location of the local file.

## Syntax

```text
public string LocalFile { get; set; }
```

## Default Value

""

## Remarks

This property specifies the location of a file on disk. This is used as the source file when calling [UploadFile](#uploadfile-method-sharepoint-component) or [UpdateResource](#updateresource-method-sharepoint-component), and as the destination file when calling [DownloadFile](#downloadfile-method-sharepoint-component).

Note: Setting this property to a non-empty value will discard any streams set using [SetDownloadStream](#setdownloadstream-method-sharepoint-component) and [SetUploadStream](#setuploadstream-method-sharepoint-component). Similarly, passing a non-null value to either of the aforementioned methods will clear this property.

# LocalHost Property ([SharePoint](#sharepoint-component) Component)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

## Syntax

```text
public string LocalHost { get; set; }
```

## Default Value

""

## Remarks

This property contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the component initiate connections (or accept in the case of server components) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the component is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

# NextChangeMarker Property ([SharePoint](#sharepoint-component) Component)

public Proxy Proxy { get; set; }
```

## Remarks

This property contains fields describing the proxy through which the component will attempt to connect.

 Please refer to the [Proxy](#proxy-type) type for a complete list of fields.

# QueryParams Property ([SharePoint](#sharepoint-component) Component)

Additional query parameters to be included in the request.

## Syntax

```text
public QueryParamList QueryParams { get; }
```

## Remarks

This is a collection of query parameters that will be added to the request. Parameters can be added via the [AddQueryParam](#addqueryparam-method-sharepoint-component) method.

 Please refer to the [QueryParam](#queryparam-type) type for a complete list of fields.

# Range Property ([SharePoint](#sharepoint-component) Component)

The range of bytes to request.

## Syntax

```text
public string Range { get; set; }
```

## Default Value

""

## Remarks

This property specifies the range of bytes to request from the server. If this property is non-empty when a [DownloadFile](#downloadfile-method-sharepoint-component) request is being constructed, a header like *Range: bytes=*Range** will be added to the request, with **Range** substituted with the specified value.

There are two valid formats for this property's value:

- **StartByte*-*
- **StartByte*-*EndByte**

Note: If the [StartByte](#startbyte-property-sharepoint-component) property is greater than zero when [DownloadFile](#downloadfile-method-sharepoint-component) is called (i.e., when a download is being resumed), and this property is non-empty, the component will automatically advance the **StartByte** value in the specified range by [StartByte](#startbyte-property-sharepoint-component) bytes when sending the *Range* header to the server. This ensures that the previously-downloaded data at the start of the specified range is not downloaded again when the download is resumed.

This property is not available at design time.

# RemoteId Property ([SharePoint](#sharepoint-component) Component)

Selects a remote resource by Id.

## Syntax

```text
public string RemoteId { get; set; }
```

## Default Value

""

## Remarks

This property selects a remote file or folder resource to operate against using its resource Id.

### Remote Id and Path Notes

Keep the following things in mind when setting the RemoteId and/or [RemotePath](#remotepath-property-sharepoint-component) properties:

- If both RemoteId and [RemotePath](#remotepath-property-sharepoint-component) are set, RemoteId is used.
- The Id or path provided must *always* be for a resource that resides in the document library currently selected by [DocumentLibrary](#documentlibrary-property-sharepoint-component).
- Some methods operate against only file *or* only folder resources; while others can operate against either one. Calling a method while RemoteId/[RemotePath](#remotepath-property-sharepoint-component) is set to the Id/path of a resource whose type is unsupported will cause the server to return an error; use the table below to determine which resource types each method supports.

| Method Name | Files | Folders |
| --- | --- | --- |
| [CopyResource](#copyresource-method-sharepoint-component) | X | X |
| [CreateFolder](#createfolder-method-sharepoint-component) | - | X |
| [CreateLink](#createlink-method-sharepoint-component) | X | X |
| [DeleteResource](#deleteresource-method-sharepoint-component) | X | X |
| [DownloadFile](#downloadfile-method-sharepoint-component) | X | - |
| [GetResourceInfo](#getresourceinfo-method-sharepoint-component) | X | X |
| [ListResources](#listresources-method-sharepoint-component) | - | X |
| [MoveResource](#moveresource-method-sharepoint-component) | X | X |
| [Search](#search-method-sharepoint-component) | - | X |
| [UpdateResource](#updateresource-method-sharepoint-component) | X | X |
| [UploadFile](#uploadfile-method-sharepoint-component) | - | X |

 **Key:** *X* = Supported; *-* = Not supported.
- Methods that support *only* folder resources can also operate against the root of the currently selected document library, just clear both RemoteId and [RemotePath](#remotepath-property-sharepoint-component).
- Some methods may have other restrictions, refer to each one for more information.

Note: The rules regarding acceptable resource types still apply if using the [RelativePath](#RelativePath) configuration setting in tandem with this property. That is, ensure that the resource that the relative path resolves to is of an acceptable type.

This property is not available at design time.

# RemotePath Property ([SharePoint](#sharepoint-component) Component)

Selects a remote resource by path.

## Syntax

```text
public string RemotePath { get; set; }
```

## Default Value

""

## Remarks

This property selects a remote file or folder resource to operate against using its path. The path provided must be absolute (that is, relative to the root of the currently selected document library).

### Remote Id and Path Notes

Keep the following things in mind when setting the [RemoteId](#remoteid-property-sharepoint-component) and/or RemotePath properties:

- If both [RemoteId](#remoteid-property-sharepoint-component) and RemotePath are set, [RemoteId](#remoteid-property-sharepoint-component) is used.
- The Id or path provided must *always* be for a resource that resides in the document library currently selected by [DocumentLibrary](#documentlibrary-property-sharepoint-component).
- Some methods operate against only file *or* only folder resources; while others can operate against either one. Calling a method while [RemoteId](#remoteid-property-sharepoint-component)/RemotePath is set to the Id/path of a resource whose type is unsupported will cause the server to return an error; use the table below to determine which resource types each method supports.

| Method Name | Files | Folders |
| --- | --- | --- |
| [CopyResource](#copyresource-method-sharepoint-component) | X | X |
| [CreateFolder](#createfolder-method-sharepoint-component) | - | X |
| [CreateLink](#createlink-method-sharepoint-component) | X | X |
| [DeleteResource](#deleteresource-method-sharepoint-component) | X | X |
| [DownloadFile](#downloadfile-method-sharepoint-component) | X | - |
| [GetResourceInfo](#getresourceinfo-method-sharepoint-component) | X | X |
| [ListResources](#listresources-method-sharepoint-component) | - | X |
| [MoveResource](#moveresource-method-sharepoint-component) | X | X |
| [Search](#search-method-sharepoint-component) | - | X |
| [UpdateResource](#updateresource-method-sharepoint-component) | X | X |
| [UploadFile](#uploadfile-method-sharepoint-component) | - | X |

 **Key:** *X* = Supported; *-* = Not supported.
- Methods that support *only* folder resources can also operate against the root of the currently selected document library, just clear both [RemoteId](#remoteid-property-sharepoint-component) and RemotePath.
- Some methods may have other restrictions, refer to each one for more information.

This property is not available at design time.

# ResourceData Property ([SharePoint](#sharepoint-component) Component)

## Remarks

This property is populated with file data after calling [DownloadFile](#downloadfile-method-sharepoint-component) if [SetDownloadStream](#setdownloadstream-method-sharepoint-component) and [LocalFile](#localfile-property-sharepoint-component) are not set.

This property can also be set before calling [UploadFile](#uploadfile-method-sharepoint-component); its data will be uploaded if [SetUploadStream](#setuploadstream-method-sharepoint-component) and [LocalFile](#localfile-property-sharepoint-component) are not set.

This property is not available at design time.

# ResourceMarker Property ([SharePoint](#sharepoint-component) Component)

A marker indicating what page of resources to return next.

## Syntax

```text
public string ResourceMarker { get; set; }
```

## Default Value

""

## Remarks

This property will be populated when [ListResources](#listresources-method-sharepoint-component) is called if the results are paged and there are more pages. To list all resources, continue to call [ListResources](#listresources-method-sharepoint-component) until this property returns empty string.

Refer to [ListResources](#listresources-method-sharepoint-component) for more information.

This property is not available at design time.

# Resources Property ([SharePoint](#sharepoint-component) Component)

A collection of resources.

## Syntax

```text
public SharePointResourceList Resources { get; }
```

## Remarks

This collection holds a list of file and folder resources.

Calling [ListResources](#listresources-method-sharepoint-component), [GetResourceInfo](#getresourceinfo-method-sharepoint-component), [Search](#search-method-sharepoint-component), or [ListChanges](#listchanges-method-sharepoint-component) will populate this collection.

Also see the [UpdateResource](#updateresource-method-sharepoint-component) method for information on how it uses this collection.

This property is not available at design time.

 Please refer to the [SharePointResource](#sharepointresource-type) type for a complete list of fields.

# ResumeURL Property ([SharePoint](#sharepoint-component) Component)

The resumable upload URL.

## Syntax

```text
public string ResumeURL { get; set; }
```

## Default Value

""

## Remarks

This property holds the URL of the resumable upload session. This is populated by the component automatically when [UseResumableUpload](#useresumableupload-property-sharepoint-component) is set to *true* and [UploadFile](#uploadfile-method-sharepoint-component) is called to initiate a new upload.

This must be set in order to resume an interrupted upload. See [UploadFile](#uploadfile-method-sharepoint-component) for details.

This property is not available at design time.

# SearchMarker Property ([SharePoint](#sharepoint-component) Component)

A marker indicating what page of search results to return next.

```text
public string SearchMarker { get; set; }
```

## Default Value

""

## Remarks

This property will be populated when [Search](#search-method-sharepoint-component) is called if the results are paged and there are more pages. To list all search results, continue to call [Search](#search-method-sharepoint-component) until this property returns empty string.

Refer to [Search](#search-method-sharepoint-component) for more information.

This property is not available at design time.

# SiteId Property ([SharePoint](#sharepoint-component) Component)

Selects a SharePoint site.

## Syntax

```text
public string SiteId { get; set; }
```

## Default Value

## Remarks

This property can be set to the Id of a specific SharePoint site to select it for use. When empty (default), the component will use the root site for the authenticated entity.

# Sites Property ([SharePoint](#sharepoint-component) Component)

A collection of sites.

## Syntax

```text
public SharePointSiteList Sites { get; }
```

## Remarks

This collection holds a list of sites (or subsites) for the currently authenticated user or application. Calling [ListSites](#listsites-method-sharepoint-component) will populate this collection.

This property is read-only and not available at design time.

 Please refer to the [SharePointSite](#sharepointsite-type) type for a complete list of fields.

# SSLAcceptServerCert Property ([SharePoint](#sharepoint-component) Component)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

## Syntax

```text
public Certificate SSLAcceptServerCert { get; set; }
```

## Remarks

If it finds any issues with the certificate presented by the server, the component will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

NOTE: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# SSLCert Property ([SharePoint](#sharepoint-component) Component)

The certificate to be used during Secure Sockets Layer (SSL) negotiation.

## Syntax

```text
public Certificate SSLCert { get; set; }
```

## Remarks

This property includes the digital certificate that the component will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the [Encoded](#Certificate_f_Encoded) field to the encoded certificate. To select a certificate, use the store and subject fields.

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# SSLProvider Property ([SharePoint](#sharepoint-component) Component)

The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.

## Syntax

```text
public SharePointSSLProviders SSLProvider { get; set; }
enum SharePointSSLProviders {
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
}
```

## Default Value

0

## Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of *0* (Automatic) is recommended and should not be changed. When set to *0* (Automatic), the component will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are as follows:

|  |  |
| --- | --- |
| 0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
| 1 (sslpPlatform) | Uses the platform/system implementation. |
| 2 (sslpInternal) | Uses the internal implementation. |

 **Additional Notes**

In most cases using the default value (Automatic) is recommended. The component will select a provider depending on the current platform.

When Automatic is selected, on Windows, the component will use the platform implementation. On Linux/macOS, the component will use the internal implementation. When TLS 1.3 is enabled via [SSLEnabledProtocols](#SSLEnabledProtocols), the component will always try and use the platform implementation. If the platform TLS 1.3 implementation is not available, the internal implementation will be used.

The .NET Standard library will always use the internal implementation on all platforms.

# SSLServerCert Property ([SharePoint](#sharepoint-component) Component)

The server certificate for the last established connection.

## Syntax

```text
public Certificate SSLServerCert { get; }
```

## Remarks

This property contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# StartByte Property ([SharePoint](#sharepoint-component) Component)

The byte offset from which to start the upload or download.

## Syntax

```text
public long StartByte { get; set; }
```

## Default Value

0

## Remarks

This property may be set to resume an upload or download; it specifies the offset in the file (or stream, when uploading) from which to resume. See [UploadFile](#uploadfile-method-sharepoint-component) and [DownloadFile](#downloadfile-method-sharepoint-component) for details about resuming uploads and downloads.

When uploading from a stream, the component will *always* seek forward in the stream if the value of StartByte is greater than 0 when [UploadFile](#uploadfile-method-sharepoint-component) is called. Keep this in mind when resuming interrupted uploads.

This property is not available at design time.

# Timeout Property ([SharePoint](#sharepoint-component) Component)

The timeout for the component.

## Syntax

```text
public int Timeout { get; set; }
```

## Default Value

60

## Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the component will wait for the operation to complete before returning control.

The component will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the component throws an exception.

NOTE: By default, all timeouts are *inactivity timeouts*, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

# UseResumableUpload Property ([SharePoint](#sharepoint-component) Component)

Whether to use resumable uploads.

## Syntax

```text
public bool UseResumableUpload { get; set; }
```

## Default Value

False

## Remarks

This property controls whether simple or resumable uploads are used when [UploadFile](#uploadfile-method-sharepoint-component) is called. The default value is *false* (simple uploads are used).

Refer to [UploadFile](#uploadfile-method-sharepoint-component) for more information.

This property is not available at design time.

# AbortUpload Method ([SharePoint](#sharepoint-component) Component)

Aborts the current resumable upload session.

## Syntax

```text
public void AbortUpload();

Async Version
public async Task AbortUpload();
public async Task AbortUpload(CancellationToken cancellationToken);
```

## Remarks

This method aborts the current resumable upload session specified by [ResumeURL](#resumeurl-property-sharepoint-component). It may be called if the current resumable upload has been interrupted and will not be resumed.

# AddQueryParam Method ([SharePoint](#sharepoint-component) Component)

Adds a query parameter to the QueryParams properties.

## Syntax

```text
public void AddQueryParam(string name, string value);

Async Version
public async Task AddQueryParam(string name, string value);
public async Task AddQueryParam(string name, string value, CancellationToken cancellationToken);
```

## Remarks

This method is used to add a query parameter to the [QueryParams](#queryparams-property-sharepoint-component) collection. *Name* specifies the name of the parameter, and *Value* specifies the value of the parameter.

All specified *Value*s will be URL encoded by the component automatically. Consult the service documentation for details on the available parameters.

# Authorize Method ([SharePoint](#sharepoint-component) Component)

Get the authorization string required to access the protected resource.

## Syntax

```text
public void Authorize();

Async Version
public async Task Authorize();
public async Task Authorize(CancellationToken cancellationToken);
```

## Remarks

This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the [ClientProfile](#OAuthSettings_f_ClientProfile) field and the [GrantType](#OAuthSettings_f_GrantType) field. This method is **not** to be used in conjunction with the [Authorization](#authorization-property-sharepoint-component) property. It should instead be used when setting the [OAuth](#oauth-property-sharepoint-component) property.

For more information, see the introduction section.

# Config Method ([SharePoint](#sharepoint-component) Component)

Sets or retrieves a configuration setting.

## Syntax

```text
public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);
```

## Remarks

Config is a generic method available in every component. It is used to set and retrieve [configuration settings](#config-settings-sharepoint-component) for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-sharepoint-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# CopyResource Method ([SharePoint](#sharepoint-component) Component)

Copies the currently selected resource.

## Syntax

```text
public void CopyResource(string parentId, string newName);

Async Version
public async Task CopyResource(string parentId, string newName);
public async Task CopyResource(string parentId, string newName, CancellationToken cancellationToken);
```

## Remarks

This method copies the resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). The following outcomes are possible depending on which of *NewName* and *ParentId* are provided:

| Parameters Provided | Effect |
| --- | --- |
| Only NewName | Copies the resource in place with the new name. |
| Only ParentId | Copies the resource to the given parent with the same name. |
| NewName and ParentId | Copies the resource to the given parent with the new name. |
| None | Exception; at least one parameter must be provided. |

*ParentId*, if provided, must either be the Id of a folder resource that already exists in the document library currently selected by [DocumentLibrary](#documentlibrary-property-sharepoint-component), or *root* (an alias for the root of the document library).

### Monitoring Copy Operations

All copy operations are asynchronous. After calling CopyResource, the [CopyStatusURL](#CopyStatusURL) configuration setting will be populated with a copy operation monitor URL.

The [PollCopyStatus](#pollcopystatus-method-sharepoint-component) method can be used to retrieve the latest status of the copy operation specified by the [CopyStatusURL](#CopyStatusURL) configuration setting. Calling [PollCopyStatus](#pollcopystatus-method-sharepoint-component) will populate the [CopyPercentDone](#copypercentdone-property-sharepoint-component), [CopyStatus](#copystatus-property-sharepoint-component), and (if applicable) [CopiedResourceId](#copiedresourceid-property-sharepoint-component) properties.

# CreateFolder Method ([SharePoint](#sharepoint-component) Component)

Creates a new folder resource.

## Syntax

```text
public string CreateFolder(string folderName);

Async Version
public async Task<string> CreateFolder(string folderName);
public async Task<string> CreateFolder(string folderName, CancellationToken cancellationToken);
```

## Remarks

This method creates a new folder resource, with the given *FolderName*, within the folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). The Id of the newly-created folder resource is returned.

To set a custom [ClientCreatedTime](#ClientCreatedTime) and/or [ClientModifiedTime](#ClientModifiedTime), call [UpdateResource](#updateresource-method-sharepoint-component) after the folder is created.

### Name Conflict Resolution

If the [RenameIfExists](#RenameIfExists) configuration setting is enabled when this method is called, and the desired *FolderName* is already in use, the server will modify the name of the new folder resource to be unique. Refer to the [RenameIfExists](#RenameIfExists) configuration setting for more information.

# CreateLink Method ([SharePoint](#sharepoint-component) Component)

Creates a resource sharing link.

## Syntax

```text
public string CreateLink(bool readOnly);

Async Version
public async Task<string> CreateLink(bool readOnly);
public async Task<string> CreateLink(bool readOnly, CancellationToken cancellationToken);
```

## Remarks

This method creates and returns a sharing link for the resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). The *ReadOnly* parameter controls whether the link provides view-only or editing access to the resource in question.

The [CreateLinkScope](#CreateLinkScope) configuration setting can also be used to control the access scope used to create the link.

```text
// Create a read-only shared link for the given file.
sharepoint.RemotePath = "/work_stuff/serious_business/best_cat_pictures.zip";
string sharingUrl = sharepoint.CreateLink(true);
```

# DeleteResource Method ([SharePoint](#sharepoint-component) Component)

Deletes the currently selected resource.

## Syntax

```text
public void DeleteResource();

Async Version
public async Task DeleteResource();
public async Task DeleteResource(CancellationToken cancellationToken);
```

## Remarks

This method deletes the resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). When deleting a folder resource, all of its contents are also deleted. If the [DeleteVersion](#DeleteVersion) config is set, the specified version of the resource will be deleted.

When resources are deleted, they are moved to the recycle bin. When resource versions are deleted, they are permanently removed and cannot be recovered.

# DownloadFile Method ([SharePoint](#sharepoint-component) Component)

Downloads the currently selected file resource.

## Syntax

```text
public void DownloadFile();

Async Version
public async Task DownloadFile();
public async Task DownloadFile(CancellationToken cancellationToken);
```

## Remarks

This method downloads the file resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component).

If a stream has been specified using [SetDownloadStream](#setdownloadstream-method-sharepoint-component), the file data will be sent through it. If a stream is not specified, and [LocalFile](#localfile-property-sharepoint-component) is set, the file will be saved to the specified location; otherwise, the file data will be held by [ResourceData](#resourcedata-property-sharepoint-component).

To download and decrypt an encrypted file, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharepoint-component) and [EncryptionPassword](#encryptionpassword-property-sharepoint-component) before calling this method.

### Download Notes

In the simplest use-case, downloading a file looks like this:

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.RemoteId = sharepoint.Resources[0].Id;
sharepoint.DownloadFile();
```

**Resuming Downloads**

The component also supports resuming failed downloads by using the [StartByte](#startbyte-property-sharepoint-component) property. If a download is interrupted, set [StartByte](#startbyte-property-sharepoint-component) to the appropriate offset before calling this method to resume the download.

```text
string downloadFile = "../MyFile.zip";
sharepoint.LocalFile = downloadFile;
sharepoint.RemoteId = sharepoint.Resources[0].Id;
sharepoint.DownloadFile();

//The transfer is interrupted and DownloadFile() above fails. Later, resume the download:

//Get the size of the partially downloaded file
sharepoint.StartByte = new FileInfo(downloadFile).Length;
sharepoint.DownloadFile();
```

**Resuming Encrypted File Downloads**

Resuming encrypted file downloads is only supported when [LocalFile](#localfile-property-sharepoint-component) was set in the initial download attempt.

If [LocalFile](#localfile-property-sharepoint-component) is set when beginning an encrypted download, the component creates a temporary file in [TempPath](#TempPath) to hold the encrypted data until the download is complete. If the download is interrupted, [DownloadTempFile](#DownloadTempFile) will be populated with the path of the temporary file that holds the partial data.

To resume, [DownloadTempFile](#DownloadTempFile) must be populated, along with [StartByte](#startbyte-property-sharepoint-component), to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to [LocalFile](#localfile-property-sharepoint-component).

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.EncryptionPassword = "password";
sharepoint.RemoteId = sharepoint.Resources[0].Id;
sharepoint.DownloadFile();

//The transfer is interrupted and DownloadFile() above fails. Later, resume the download:

//Get the size of the partially download temp file
sharepoint.StartByte = new FileInfo(sharepoint.Config("DownloadTempFile")).Length;
sharepoint.DownloadFile();
```

# GetCurrentChangeMarker Method ([SharePoint](#sharepoint-component) Component)

## Syntax

```text
public void GetDocumentLibraryInfo();

Async Version
public async Task GetDocumentLibraryInfo();
public async Task GetDocumentLibraryInfo(CancellationToken cancellationToken);
```

## Remarks

This method retrieves information about the document library currently selected by [DocumentLibrary](#documentlibrary-property-sharepoint-component).

Calling this method will fire the [DocumentLibraryList](#documentlibrarylist-event-sharepoint-component) event, and will populate the [DocumentLibraries](#documentlibraries-property-sharepoint-component) collection with a single item (clearing any previously-held items in the process).

# GetResourceInfo Method ([SharePoint](#sharepoint-component) Component)

Gets information about the currently selected resource.

## Syntax

```text
public void GetResourceInfo();

Async Version
public async Task GetResourceInfo();
public async Task GetResourceInfo(CancellationToken cancellationToken);
```

## Remarks

This method retrieves information about the resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component).

Calling this method will fire the [ResourceList](#resourcelist-event-sharepoint-component) event, and will populate the [Resources](#resources-property-sharepoint-component) collection with a single item (clearing any previously-held items in the process).

# Interrupt Method ([SharePoint](#sharepoint-component) Component)

This method interrupts the current method.

## Syntax

```text
public void Interrupt();

Async Version
public async Task Interrupt();
public async Task Interrupt(CancellationToken cancellationToken);
```

## Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

# ListChanges Method ([SharePoint](#sharepoint-component) Component)

Lists changes to resources in the currently selected document library.

## Syntax

```text
public void ListChanges();

Async Version
public async Task ListChanges();
public async Task ListChanges(CancellationToken cancellationToken);
```

## Remarks

This method lists changes to resources in the document library currently selected by [DocumentLibrary](#documentlibrary-property-sharepoint-component).

### Starting from a Baseline State

For most use-cases, it is necessary to obtain a baseline of the full document library hierarchy in order to have a context onto which later changes can be applied.

To obtain a full document library hierarchy baseline, ensure that both [ChangeMarker](#changemarker-property-sharepoint-component) and [NextChangeMarker](#nextchangemarker-property-sharepoint-component) are empty, and then call ListChanges. Then follow the process described in the "General Usage" section (below) until [ChangeMarker](#changemarker-property-sharepoint-component) is empty, keeping in mind that the results being returned are not necessarily* changes, but rather the current state of all resources in the document library.

**If any resources in the document library are changed before all result pages of the baseline have been returned, SharePoint may append those change items to the end of the baseline's results. Refer to the "Usage Considerations" section (below) for more information.*

### Starting from the Latest State

For use-cases that *don't* require a baseline (e.g., perhaps an application just displays a "ticker" with change information), call [GetCurrentChangeMarker](#getcurrentchangemarker-method-sharepoint-component). This will populate [NextChangeMarker](#nextchangemarker-property-sharepoint-component) immediately.

### General Usage

When this method is called, it will use the change marker stored in either [ChangeMarker](#changemarker-property-sharepoint-component) or [NextChangeMarker](#nextchangemarker-property-sharepoint-component) (only one can be populated at a time) to request the next page of changes. This method causes the [ResourceList](#resourcelist-event-sharepoint-component) event to fire once for each change, and will also populate the [Resources](#resources-property-sharepoint-component) collection.

If there are still more changes available to list when this method returns, the [ChangeMarker](#changemarker-property-sharepoint-component) property will be populated. Continue to call this method until [ChangeMarker](#changemarker-property-sharepoint-component) is empty to accumulate all pages of results in the [Resources](#resources-property-sharepoint-component) collection. (Once there aren't any more changes available to list, the [NextChangeMarker](#nextchangemarker-property-sharepoint-component) property will be populated instead.) Alternatively, the [AccumulatePages](#AccumulatePages) configuration setting can be disabled to clear the [Resources](#resources-property-sharepoint-component) collection every time a page of results is returned.

When [NextChangeMarker](#nextchangemarker-property-sharepoint-component) is populated, it is always populated with a value that (at the time of population) points to the most current state. (Since "the most current state" implies that there are no further changes to list, calling ListChanges immediately after [NextChangeMarker](#nextchangemarker-property-sharepoint-component) is populated will not return any further changes.)

**Example of Getting a Baseline and then Listing Changes**

```csharp
// Get a full document library hierarchy baseline first.
Sharepoint sharepoint = new Sharepoint();

sharepoint.ListChanges();
do {
  // Continue to call ListChanges() until ChangeMarker is the empty string (indicating there
  // are no more changes to list).
  sharepoint.ListChanges();
} while (sharepoint.ChangeMarker.Length > 0);

for (int i = 0; i < sharepoint.Resources.Count; i++) {
  // Apply the baseline document library state.
}

// Now NextChangeMarker will be populated. If we were to call ListChanges() again right now,
// nothing would be listed and NextChangeMarker would still be populated.

// Wait 2 minutes and then try to list changes again. Assume something changes while we wait.
Thread.Sleep(120000);

sharepoint.ListChanges();
do {
  sharepoint.ListChanges();
} while (sharepoint.ChangeMarker.Length > 0);

for (int i = 0; i < sharepoint.Resources.Count; i++) {
  // Apply the changes.
}
```

### Usage Considerations

 Keep the following things in mind when working with SharePoint changes:

- When listing changes, certain resource properties are not included. For example, resource paths are not returned; always use resource Ids when tracking changes.
- It is possible for a resource, uniquely identified by its Id, to appear more than once in a change set. (This can happen if changes are being listed, and then a change occurs before all result pages in the change set are returned; SharePoint will then typically append the new change to the end of the current change set.) Since a SharePoint change always reflects the latest state of a resource, just use the latest one.
- SharePoint will report a change when a resource is created, renamed, modified, or deleted; but it only explicitly specifies deletions. However, it is easy to differentiate between the other change events by keeping track of resource Ids, names, and last modified times; and then comparing old and new values when changes arrive.

# ListDocumentLibraries Method ([SharePoint](#sharepoint-component) Component)

Lists the document libraries in the current site.

## Syntax

```text
public void ListDocumentLibraries();

Async Version
public async Task ListDocumentLibraries();
public async Task ListDocumentLibraries(CancellationToken cancellationToken);

public async Task ListResources();
public async Task ListResources(CancellationToken cancellationToken);
```

## Remarks

This method lists resources in the folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component).

Calling this method will fire the [ResourceList](#resourcelist-event-sharepoint-component) event once for each resource, and will also populate the [Resources](#resources-property-sharepoint-component) collection.

If there are still more resources available to list when this method returns, the [ResourceMarker](#resourcemarker-property-sharepoint-component) property will be populated. Continue to call this method until [ResourceMarker](#resourcemarker-property-sharepoint-component) is empty to accumulate all pages of results in the [Resources](#resources-property-sharepoint-component) collection. Alternatively, the [AccumulatePages](#AccumulatePages) configuration setting can be disabled to clear the [Resources](#resources-property-sharepoint-component) collection every time a page of results is returned.

For more complex queries, use the [Search](#search-method-sharepoint-component) method.

```text
// ResourceList event handler.
sharepoint.OnResourceList += (s, e) => {
  Console.WriteLine(e.Name);
};

// (Assume that the RemoteId property isn't set; it takes precedence if it is.)
sharepoint.RemotePath = "/work_files/serious_business/cats";
do {

} while (!string.IsNullOrEmpty(sharepoint.ResourceMarker));

for (int i = 0; i < sharepoint.Resources.Count; i++) {
  // Process resources here.
}
```

List the sites currently accessible by the authenticated entity.

## Syntax

```text
public void ListSites();

Async Version
public async Task ListSites();
public async Task ListSites(CancellationToken cancellationToken);
```

## Remarks

This method lists the sites of the currently authenticated entity. Calling this method will fire the [SiteList](#sitelist-event-sharepoint-component) event once for each site, and will also clear and populate the [Sites](#sites-property-sharepoint-component) collection.

The exact endpoint that is requested (and the parameters for the request) can be modified by the [ListSitesParams](#ListSitesParams) configuration setting. For example, this setting can be changed to make a search or list the subsites of a specified site. See the [ListSitesParams](#ListSitesParams) entry for more information.

**Basic List**

```text
  sharepoint.ListSites();
  string siteId = sharepoint.Sites[0].Id;

public async Task RetrieveCurrentUser(CancellationToken cancellationToken);
```

## Remarks

This method retrieves the signed-in user's identity from the Microsoft Graph */me* endpoint and populates the [CurrentUser](#currentuser-property-sharepoint-component) property. For more information, refer to [CurrentUser](#currentuser-property-sharepoint-component).

The *user.read* permission is required in the [OAuth](#oauth-property-sharepoint-component) authorization scope. For Microsoft personal accounts this must be included explicitly; for work/school accounts it is granted implicitly alongside any delegated permission.

# Search Method ([SharePoint](#sharepoint-component) Component)

Searches for resources that match the specified query.

## Syntax

```text
public void Search(string query);

Async Version
public async Task Search(string query);
public async Task Search(string query, CancellationToken cancellationToken);
```

## Remarks

This method searches for resources that match the given *Query* within the folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). The value provided for *Query* will automatically be URL-encoded.

Calling this method will fire the [ResourceList](#resourcelist-event-sharepoint-component) event once for each search result, and will also populate the [Resources](#resources-property-sharepoint-component) collection.

If there are still more search results available to list when this method returns, the [SearchMarker](#searchmarker-property-sharepoint-component) property will be populated. Continue to call this method until [SearchMarker](#searchmarker-property-sharepoint-component) is empty to accumulate all pages of results in the [Resources](#resources-property-sharepoint-component) collection.

# SendCustomRequest Method ([SharePoint](#sharepoint-component) Component)

Sends a custom request to the Microsoft Graph API.

## Syntax

```text
public void SendCustomRequest(string httpMethod, string requestPath, string requestBody);

Async Version
public async Task SendCustomRequest(string httpMethod, string requestPath, string requestBody);
public async Task SendCustomRequest(string httpMethod, string requestPath, string requestBody, CancellationToken cancellationToken);
```

## Remarks

This method can be used to send arbitrary requests to the Microsoft Graph API.

Valid values for *HttpMethod* are:

- *GET* (default if empty)
- *HEAD*
- *POST*
- *PUT*
- *PATCH*
- *DELETE*

The value passed for *RequestPath* must already be URL-encoded in a manner acceptable to the Microsoft Graph API. The *RequestBody* parameter may be empty if not needed.

### Usage

When this method is called, the component does the following:

1.  Builds a request URL, including query parameters, as follows:

  - The specified *RequestPath* is appended to the Microsoft Graph API's "stable" endpoint, *https://graph.microsoft.com/v1.0* (however, see note below).
  - All query parameters in the [QueryParams](#queryparams-property-sharepoint-component) collection are added to the request URL.

2. Sends the request using the specified *HttpMethod*, the request URL build in step 1, the header information held by [Authorization](#authorization-property-sharepoint-component) and [OtherHeaders](#otherheaders-property-sharepoint-component), and the given *RequestBody* (if non-empty).
3. Stores the response headers in the [ParsedHeaders](#parsedheaders-property-sharepoint-component) collection, and the response body in the stream specified using [SetDownloadStream](#setdownloadstream-method-sharepoint-component), the specified [LocalFile](#localfile-property-sharepoint-component), or [ResourceData](#resourcedata-property-sharepoint-component) (using the same logic as [DownloadFile](#downloadfile-method-sharepoint-component)).

If the response body is JSON data, the [XPath](#XPath), [XText](#XText), and other **X*** configuration settings can then be used to navigate and extract information from it.

Note: Some responses returned by the Graph API include fully-qualified Graph API URLs for clients to use to obtain additional information (the next page of results in a listing, details about a long-running operation, etc.). As a convenience, any fully-qualified URL that begins with *https://graph.microsoft.com/* can be passed for *RequestPath* to have the component make a request against it.

# SetDownloadStream Method ([SharePoint](#sharepoint-component) Component)

Sets the stream to which downloaded data will be written.

## Syntax

```text
public void SetDownloadStream(System.IO.Stream downloadStream);

Async Version
public async Task SetDownloadStream(System.IO.Stream downloadStream);
public async Task SetDownloadStream(System.IO.Stream downloadStream, CancellationToken cancellationToken);
```

## Remarks

If a download stream is set before data is downloaded, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.

Note: Passing a non-null value for *DownloadStream* will cause [LocalFile](#localfile-property-sharepoint-component) to be cleared. Similarly, setting [LocalFile](#localfile-property-sharepoint-component) to a non-empty value will discard any stream set using this method.

# SetUploadStream Method ([SharePoint](#sharepoint-component) Component)

Sets the stream from which data is read when uploading.

## Syntax

```text
public void SetUploadStream(System.IO.Stream uploadStream);

Async Version
public async Task SetUploadStream(System.IO.Stream uploadStream);
public async Task SetUploadStream(System.IO.Stream uploadStream, CancellationToken cancellationToken);
```

## Remarks

If an upload stream is set before data is uploaded, the content of the stream will be read by the component and uploaded to the server. The stream should be open and normally set to position 0.

Note: Passing a non-null value for *UploadStream* will cause [LocalFile](#localfile-property-sharepoint-component) to be cleared. Similarly, setting [LocalFile](#localfile-property-sharepoint-component) to a non-empty value will discard any stream set using this method.

# UpdateResource Method ([SharePoint](#sharepoint-component) Component)

Updates the currently selected resource.

## Syntax

```text
public void UpdateResource();

Async Version
public async Task UpdateResource();
public async Task UpdateResource(CancellationToken cancellationToken);
```

## Remarks

This method updates the metadata for the file or folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). For file resources, the file data can optionally be updated as well.

### Usage

 There must be a [SharePointResource](#sharepointresource-type) collection whose [Id](#SharePointResource_f_Id) or [Path](#SharePointResource_f_Path) field matches [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component) before this method is called.

1. If necessary, call [GetResourceInfo](#getresourceinfo-method-sharepoint-component) or [ListResources](#listresources-method-sharepoint-component) to ensure an item with the resource's latest information is present in the [Resources](#resources-property-sharepoint-component) collection.
2. Modify the [SharePointResource](#sharepointresource-type) item's fields as desired; the following fields are supported:

  - Description (only updated if not empty)
  - [Name](#SharePointResource_f_Name)
  - [ParentId](#SharePointResource_f_ParentId) (only updated if not empty)
  - [ParentPath](#SharePointResource_f_ParentPath) (only updated if not empty and [ParentId](#SharePointResource_f_ParentId) *is* empty)

 If the [ClientCreatedTime](#ClientCreatedTime) and/or [ClientModifiedTime](#ClientModifiedTime) configuration settings is non-empty, the corresponding timestamps will be sent as well.
3. For file resources, you may call [SetUploadStream](#setuploadstream-method-sharepoint-component) or set [LocalFile](#localfile-property-sharepoint-component) or [ResourceData](#resourcedata-property-sharepoint-component) if you wish to update the file data on the server. (Refer to [UploadFile](#uploadfile-method-sharepoint-component) for more information about simple vs. resumable uploads and encrypting the file data before uploading.)
4. Finally, call this method to update the resource.

```text
// Load the latest information about the resource into the Resources collection.
sharepoint.RemotePath = "/folder/CoolStuff1.txt";
sharepoint.GetResourceInfo();

// We'll update the file resource's name, description, and content.
sharepoint.ResourceData = "new file content";
sharepoint.Resources[0].Name = "CoolStuff2.txt";
sharepoint.Resources[0].Description = "This is a text file with cool stuff in it";

sharepoint.UpdateResource();
```

### Name Conflict Resolution

 When updating a resource's name and/or parent, keep in mind that the server's name conflict resolution behavior will follow these steps:

1. If the [RenameIfExists](#RenameIfExists) configuration setting is enabled, the server will modify the new name of the resource to be unique, if necessary. Refer to the [RenameIfExists](#RenameIfExists) configuration setting for more information.
2. Otherwise, if the [Overwrite](#overwrite-property-sharepoint-component) property is enabled, the server will replace the existing (other) resource with the one being updated.
3. Otherwise, the server will return an error.

# UploadFile Method ([SharePoint](#sharepoint-component) Component)

Uploads a new file resource.

## Syntax

```text
public string UploadFile(string fileName);

Async Version
public async Task<string> UploadFile(string fileName);
public async Task<string> UploadFile(string fileName, CancellationToken cancellationToken);
```

## Remarks

This method uploads a new file resource, with the given *FileName* (which should include a file extension), to the folder resource currently selected by [RemoteId](#remoteid-property-sharepoint-component) or [RemotePath](#remotepath-property-sharepoint-component). The Id of the newly-created file resource is returned.

If the [ClientCreatedTime](#ClientCreatedTime) and/or [ClientModifiedTime](#ClientModifiedTime) configuration settings are non-empty when this method is called, the corresponding timestamps will be submitted with the file upload request.

If [SetUploadStream](#setuploadstream-method-sharepoint-component) has been used to set an upload stream, it will take priority as the file data source. If [LocalFile](#localfile-property-sharepoint-component) is set the file will be uploaded from the specified path. If [LocalFile](#localfile-property-sharepoint-component) is not set the data in [ResourceData](#resourcedata-property-sharepoint-component) will be used.

To encrypt the file before uploading it, set [EncryptionAlgorithm](#encryptionalgorithm-property-sharepoint-component) and [EncryptionPassword](#encryptionpassword-property-sharepoint-component).

### Upload Notes

SharePoint offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

**Simple**

By default the component uses the simple upload mechanism.

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.UploadFile("MyFile.zip");
```

**Resumable**

To enable resumable uploads set [UseResumableUpload](#useresumableupload-property-sharepoint-component) to *true*. This is recommended for large files. The component will automatically fragment the specified file into smaller pieces and upload each individually. [FragmentSize](#FragmentSize) may be set to specify the size of the fragment if desired. The default fragment size is 10 MB.

When [UseResumableUpload](#useresumableupload-property-sharepoint-component) is set to *true* and UploadFile is called, a resumable upload session is started by the component. [ResumeURL](#resumeurl-property-sharepoint-component) is populated with a URL identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the [FragmentComplete](#fragmentcomplete-event-sharepoint-component) event fires after each fragment is uploaded to indicate overall progress. The component also updates [StartByte](#startbyte-property-sharepoint-component) as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that [ResumeURL](#resumeurl-property-sharepoint-component) and [StartByte](#startbyte-property-sharepoint-component) are populated (if the same instance of the component is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call UploadFile again to resume the upload at the specified [StartByte](#startbyte-property-sharepoint-component) offset.

Note that if the upload is not resumed after some time the upload session will expire. [PollUploadStatus](#polluploadstatus-method-sharepoint-component) may be used to check the status of a resumable upload, including when it will expire (which is stored in the [UploadExpDate](#UploadExpDate) configuration setting). An interrupted upload can be aborted explicitly using the [AbortUpload](#abortupload-method-sharepoint-component) method.

```text
sharepoint.LocalFile = "../MyFile.zip";
sharepoint.UploadFile("MyFile.zip");

//The transfer is interrupted and UploadFile() above fails. Later, resume the download.
//Using the same instance StartByte and ResumeURL are already populated from the previous
//upload attempt.
sharepoint.UploadFile("MyFile.zip");
```

```text
MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip"));
sharepoint.SetUploadStream(uploadStream);
sharepoint.UploadFile("MyFile.zip");

//The transfer is interrupted and UploadFile() above fails. Later, resume the download.
//Using the same instance StartByte and ResumeURL are already populated from the previous
//upload attempt.
//You MUST reset the stream's position to where it was when you first started the upload!
uploadStream.Position = 0;
sharepoint.UploadFile("MyFile.zip");
```

### Name Conflict Resolution

 If the desired *FileName* is already in use, the server's name conflict resolution behavior will follow these steps:

1. If the [RenameIfExists](#RenameIfExists) configuration setting is enabled, the server will modify the name of the new file resource to be unique. Refer to the [RenameIfExists](#RenameIfExists) configuration setting for more information.
2. Otherwise, if the [Overwrite](#overwrite-property-sharepoint-component) property is enabled, the server will replace the existing file resource with the newly-uploaded one.
3. Otherwise, the server will return an error.

# DocumentLibraryList Event ([SharePoint](#sharepoint-component) Component)

Fires once for each document library returned when listing document libraries.

## Syntax

```text
public event OnDocumentLibraryListHandler OnDocumentLibraryList;

public delegate void OnDocumentLibraryListHandler(object sender, SharePointDocumentLibraryListEventArgs e);

public class SharePointDocumentLibraryListEventArgs : EventArgs {
  public string Id { get; }
  public string Name { get; }
  public string Description { get; }
  public string OwnerId { get; }
  public string OwnerName { get; }
}
```

## Remarks

This event fires once for each document libraries returned when [ListDocumentLibraries](#listdocumentlibraries-method-sharepoint-component) or [GetDocumentLibraryInfo](#getdocumentlibraryinfo-method-sharepoint-component) is called.

*Id* is the Id of the document library.

*Name* is the name of the document library.

*Description* holds the description of the document library.

*OwnerId* is the Id of the document library's owner.

*OwnerName* is the name of the document library's owner.

# EndTransfer Event ([SharePoint](#sharepoint-component) Component)

Fired when a document finishes transferring.

## Syntax

```text
public event OnEndTransferHandler OnEndTransfer;

public delegate void OnEndTransferHandler(object sender, SharePointEndTransferEventArgs e);

public class SharePointEndTransferEventArgs : EventArgs {
  public int Direction { get; }
}
```

## Remarks

This event is fired first when the client finishes sending data to the server (in a *POST* or *PUT* request) and then when the document text finishes transferring from the server to the local host.

The *Direction* parameter shows whether the client (0) or the server (1) is sending the data.

# Error Event ([SharePoint](#sharepoint-component) Component)

Fired when information is available about errors during data delivery.

## Syntax

```text
public event OnErrorHandler OnError;

public delegate void OnErrorHandler(object sender, SharePointErrorEventArgs e);

public class SharePointErrorEventArgs : EventArgs {
  public int ErrorCode { get; }
  public string Description { get; }
}
```

## Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component throws an exception.

The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-sharepoint-component) section.

# FragmentComplete Event ([SharePoint](#sharepoint-component) Component)

Fires after each fragment of a resumable upload is completed.

## Syntax

```text
public event OnFragmentCompleteHandler OnFragmentComplete;

public delegate void OnFragmentCompleteHandler(object sender, SharePointFragmentCompleteEventArgs e);

public class SharePointFragmentCompleteEventArgs : EventArgs {
  public int FragmentNumber { get; }
  public int FragmentCount { get; }
  public bool Interrupt { get; set; }
}
```

## Remarks

When [UseResumableUpload](#useresumableupload-property-sharepoint-component) is *true* and [UploadFile](#uploadfile-method-sharepoint-component) is called, this event will fire after each fragment is uploaded, providing an indication of overall upload progress.

*FragmentNumber* is the number of the current fragment that has completed. This value starts at *1*.

*FragmentCount* is the total number of fragments that will be uploaded.

*Interrupt* can be set to *true* to interrupt the upload. The upload may be resumed later.

# Header Event ([SharePoint](#sharepoint-component) Component)

Fired every time a header line comes in.

## Syntax

```text
public event OnHeaderHandler OnHeader;

public delegate void OnHeaderHandler(object sender, SharePointHeaderEventArgs e);

public class SharePointHeaderEventArgs : EventArgs {
  public string Field { get; }
  public string Value { get; }
}
```

## Remarks

The *Field* parameter contains the name of the HTTP header (which is the same as it is delivered). The *Value* parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the *Field* parameter contains "" (empty string).

# Log Event ([SharePoint](#sharepoint-component) Component)

Fired once for each log message.

## Syntax

```text
public event OnLogHandler OnLog;

public delegate void OnLogHandler(object sender, SharePointLogEventArgs e);

public class SharePointLogEventArgs : EventArgs {
  public int LogLevel { get; }
  public string Message { get; }
  public string LogType { get; }
}
```

## Remarks

This event is fired once for each log message generated by the component. The verbosity is controlled by the [LogLevel](#LogLevel) setting.

*LogLevel* indicates the level of message. Possible values are as follows:

|  |  |
| --- | --- |
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

*Message* is the log entry.

*LogType* identifies the type of log entry. Possible values are as follows:

- "Info"
- "RequestHeaders"
- "ResponseHeaders"
- "RequestBody"
- "ResponseBody"
- "ProxyRequest"
- "ProxyResponse"
- "FirewallRequest"
- "FirewallResponse"

# Progress Event ([SharePoint](#sharepoint-component) Component)

Fires during an upload or download to indicate transfer progress.

## Syntax

```text
public event OnProgressHandler OnProgress;

public delegate void OnProgressHandler(object sender, SharePointProgressEventArgs e);

public class SharePointProgressEventArgs : EventArgs {
  public int Direction { get; }
  public long BytesTransferred { get; }
  public long TotalBytes { get; }
  public int PercentDone { get; }
}
```

## Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time *PercentDone* increases by one percent; the [ProgressStep](#ProgressStep) configuration setting can be used to alter this behavior.

*Direction* indicates whether the transfer is an upload (*0*) or a download (*1*).

*BytesTransferred* reflects the number of bytes that have been transferred so far, or *0* if the transfer is starting (however, see note below).

*TotalBytes* reflects the total number of bytes that are to be transferred, or *-1* if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

*PercentDone* reflects the overall progress of the transfer, or *-1* if the progress cannot be calculated.

NOTE: By default, the component tracks transfer progress *absolutely*. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred *before* the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a *BytesTransferred* value of *10485760* (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the [ProgressAbsolute](#ProgressAbsolute) configuration setting, in which case the component will treat resumed transfers as "new" transfers. In this case, the *BytesTransferred* parameter will always be *0* the first time this event fires, regardless of whether the transfer is new or being resumed.

# ResourceList Event ([SharePoint](#sharepoint-component) Component)

Fires once for each resource returned when listing resources or changes.

## Syntax

```text
public event OnResourceListHandler OnResourceList;

public delegate void OnResourceListHandler(object sender, SharePointResourceListEventArgs e);

public class SharePointResourceListEventArgs : EventArgs {
  public string Id { get; }
  public string Name { get; }
  public string Path { get; }
  public int ResourceType { get; }
  public string CreatedTime { get; }
  public string ModifiedTime { get; }
  public long Size { get; }
  public string ETag { get; }
  public bool Deleted { get; }
}
```

## Remarks

This event fires once for each resource returned when [ListResources](#listresources-method-sharepoint-component), [GetResourceInfo](#getresourceinfo-method-sharepoint-component), [Search](#search-method-sharepoint-component), or [ListChanges](#listchanges-method-sharepoint-component) is called.

*Id* is the Id of the resource.

*Name* is the name of the resource.

*Path* is the path to the resource on the server. This parameter will always be empty for [ListChanges](#listchanges-method-sharepoint-component).

*ResourceType* reflects the resource's type. Possible values are:

|  |  |
| --- | --- |
| 0 (odrtFile) | A file. |
| 1 (odrtFolder) | A folder. |

*CreatedTime* and *ModifiedTime* reflect the resource's creation and last modified timestamps. Timestamps are formatted according to ISO 8601 and are always in UTC time.

*Size* is the size of the resource (for folders, their contents' total size), in bytes. This parameter will always be -1 for [ListChanges](#listchanges-method-sharepoint-component).

*ETag* is the ETag of the resource.

*Deleted* indicates whether the resource has been deleted. This parameter is only applicable for [ListChanges](#listchanges-method-sharepoint-component), it will always be *false* otherwise.

# SiteList Event ([SharePoint](#sharepoint-component) Component)

Fires once for each site returned when listing sites.

## Syntax

```text
public event OnSiteListHandler OnSiteList;

public delegate void OnSiteListHandler(object sender, SharePointSiteListEventArgs e);

public class SharePointSiteListEventArgs : EventArgs {
  public string Id { get; }
  public string Name { get; }
  public string URL { get; }
}
```

## Remarks

This event fires once for each site returned when [ListSites](#listsites-method-sharepoint-component) is called.

*Id* is the Id of the site.

*Name* is the name of the site.

*URL* is the site's web URL which can be used to view the site online.

# SSLServerAuthentication Event ([SharePoint](#sharepoint-component) Component)

Fired after the server presents its certificate to the client.

## Syntax

```text
public event OnSSLServerAuthenticationHandler OnSSLServerAuthentication;

public delegate void OnSSLServerAuthenticationHandler(object sender, SharePointSSLServerAuthenticationEventArgs e);

public class SharePointSSLServerAuthenticationEventArgs : EventArgs {
  public string CertEncoded { get; }  public byte[] CertEncodedB { get; }
  public string CertSubject { get; }
  public string CertIssuer { get; }
  public string Status { get; }
  public bool Accept { get; set; }
}
```

## Remarks

During this event, the client can decide whether or not to continue with the connection process. The *Accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

 When *Accept* is False, *Status* shows why the verification failed (otherwise, *Status* contains the string *OK*). If it is decided to continue, you can override and accept the certificate by setting the *Accept* parameter to True.

# SSLStatus Event ([SharePoint](#sharepoint-component) Component)

Fired when secure connection progress messages are available.

## Syntax

```text
public event OnSSLStatusHandler OnSSLStatus;

public delegate void OnSSLStatusHandler(object sender, SharePointSSLStatusEventArgs e);

public class SharePointSSLStatusEventArgs : EventArgs {
  public string Message { get; }
}
```

## Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

# StartTransfer Event ([SharePoint](#sharepoint-component) Component)

Fired when a document starts transferring (after the headers).

## Syntax

```text
public event OnStartTransferHandler OnStartTransfer;

public delegate void OnStartTransferHandler(object sender, SharePointStartTransferEventArgs e);

public class SharePointStartTransferEventArgs : EventArgs {
  public int Direction { get; }
}
```

## Remarks

This event is fired first when the client starts sending data to the server (in a *POST* or *PUT* request) and then when the document text starts transferring from the server to the local host.

The *Direction* parameter shows whether the client (0) or the server (1) is sending the data.

# Transfer Event ([SharePoint](#sharepoint-component) Component)

Fired while a document transfers (delivers document).

## Syntax

```text
public event OnTransferHandler OnTransfer;

public delegate void OnTransferHandler(object sender, SharePointTransferEventArgs e);

public class SharePointTransferEventArgs : EventArgs {
  public int Direction { get; }
  public long BytesTransferred { get; }
  public int PercentDone { get; }
  public string Text { get; }  public byte[] TextB { get; }
}
```

## Remarks

The *Text* parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The *BytesTransferred* parameter contains the number of bytes transferred in this *Direction* since the beginning of the document text (excluding HTTP response headers).

The *Direction* parameter shows whether the client (0) or the server (1) is sending the data.

The *PercentDone* parameter shows the progress of the transfer in the corresponding direction. If *PercentDone* can not be calculated the value will be -1.

NOTE: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

```text
public Certificate(string certificateFile);
```

 Opens * CertificateFile * and reads out the contents as an X.509 public key.

```text
public Certificate(byte[] encoded);
```

 Parses * Encoded * as an X.509 public key.

```text
public Certificate(CertStoreTypes storeType, string store, string storePassword, string subject);
```

 * StoreType * identifies the type of certificate store to use. See for descriptions of the different certificate stores. * Store * is a file containing the certificate store. * StorePassword * is the password used to protect the store.

 After the store has been successfully opened, the component will attempt to find the certificate identified by * Subject * . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The * Subject * parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

```text
public Certificate(CertStoreTypes storeType, string store, string storePassword, string subject, string configurationString);
```

 * StoreType * identifies the type of certificate store to use. See for descriptions of the different certificate stores. * Store * is a file containing the certificate store. * StorePassword * is the password used to protect the store.

 * ConfigurationString * is a newline-separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CryptoAPI option. The default value is True (the key is persisted). "Thumbprint" - an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to the * cstUser * , * cstMachine * , * cstPublicKeyFile * , and * cstPFXFile * store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations.

 After the store has been successfully opened, the component will attempt to find the certificate identified by * Subject * . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The * Subject * parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

# Config Settings ([SharePoint](#sharepoint-component) Component)

 The component accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these *internal properties* is provided through the [Config](#config-method-sharepoint-component) method.

### SharePoint Config Settings

**AccumulatePages**: Whether the component should accumulate subsequent pages of results when listing them.This setting controls how the component behaves when listing multiple pages of results. If this setting is enabled, each successive page of results will be appended to the appropriate collection property until the last page of results has been listed (at which point the next list call will cause said collection to be cleared first). If this setting is disabled, the collection will be cleared every time a page of results is returned.

By default, this setting is enabled, allowing all pages of results to be accumulated in the appropriate collection property.

**ClientCreatedTime**: The client-side creation time.This setting may be set to an appropriately-formatted timestamp before calling [UploadFile](#uploadfile-method-sharepoint-component), [CreateFolder](#createfolder-method-sharepoint-component), or [UpdateResource](#updateresource-method-sharepoint-component) to set the client-side creation time for a resource.

Timestamps are formatted according to ISO 8601 and are always in UTC time.

**ClientModifiedTime**: The client-side last modified time.This setting may be set to an appropriately-formatted timestamp before calling [UploadFile](#uploadfile-method-sharepoint-component), [CreateFolder](#createfolder-method-sharepoint-component), or [UpdateResource](#updateresource-method-sharepoint-component) to set the client-side last modified time for the resource.

Timestamps are formatted according to ISO 8601 and are always in UTC time.

**CopyStatusURL**: The URL from which copy status information is obtained.This setting specifies the URL used by [PollCopyStatus](#pollcopystatus-method-sharepoint-component) to retrieve information about ongoing copy operations. It is populated after calling [CopyResource](#copyresource-method-sharepoint-component).

When using the same instance of the component this setting typically does not need to be set. It may optionally be set to a URL from a previous copy operation before calling [PollCopyStatus](#pollcopystatus-method-sharepoint-component).

**CopyToDocumentLibrary**: The Id of the document library to copy resources to.Can be set to a valid document library Id before calling [CopyResource](#copyresource-method-sharepoint-component) to copy the resource to that document library. Note that, when using this setting, any value passed for the [CopyResource](#copyresource-method-sharepoint-component) method's *ParentId* parameter *must* be the Id of a folder resource in the destination document library, or the server will return an error.

**CreateLinkScope**: The access scope that should be used to create links.This setting is used to specify the access scope that links should be created with when [CreateLink](#createlink-method-sharepoint-component) is called. Possible values are:

- *anonymous* (default) - Allows anyone with the link to access the resource.
- *organization* - Only allows those within the currently authenticated user's organization (who have the link) to access the resource. NOTE: Not valid when authenticated with a personal Microsoft account.

**DownloadTempFile**: The temporary file used when downloading encrypted data.This setting specifies the temporary file used when downloading encrypted data.

When downloading encrypted data with [LocalFile](#localfile-property-sharepoint-component) set, the component will automatically create a temporary file at [TempPath](#TempPath) to hold the encrypted file contents. When the download is complete, the data is decrypted to [LocalFile](#localfile-property-sharepoint-component).

If the download is interrupted, the specified file will hold the partially downloaded encrypted file contents. Before resuming the download, this setting must be set to a valid file containing the partially encrypted file contents. See [DownloadFile](#downloadfile-method-sharepoint-component) for details.

**EncryptionIV**: The initialization vector to be used for encryption/decryption.When encrypting or decrypting a file, this setting may be set to specify the initialization vector. Normally the component will derive this value automatically from [EncryptionPassword](#encryptionpassword-property-sharepoint-component).

This setting accepts a hex encoded value.

**EncryptionKey**: The key to use during encryption/decryption.When encrypting or decrypting a file, this setting may be set to specify the key to use. Normally the component will derive this value automatically from [EncryptionPassword](#encryptionpassword-property-sharepoint-component).

This setting accepts a hex encoded value.

**EncryptionPasswordKDF**: The KDF algorithm to use during password based encryption and decryption.This setting specified the Key Derivation Function (KDF) used to derive a key from the specified [EncryptionPassword](#encryptionpassword-property-sharepoint-component). Possible values are:

- 0 (default) - PBKDF1
- 1 - PBKDF2

 Note: PBKDF1 is not FIPS compliant. When operating in FIPS mode PBKDF2 should be used.

**Endpoint**: The Microsoft Graph endpoint that the component should use.This setting specifies the Microsoft Graph endpoint that the component should use. By default, the component uses the global Microsoft Graph endpoint, *https://graph.microsoft.com*.

In most cases, the default endpoint is the correct choice. This setting should only be changed if the component needs to use an endpoint associated with a specific [National Cloud Deployment](https://docs.microsoft.com/en-us/graph/deployments), in which case it should be set to one of the values shown in this table:

| National Cloud | Endpoint |
| --- | --- |
| Microsoft Graph global service | https://graph.microsoft.com (default) |
| Microsoft Graph for US Government | L4: https://graph.microsoft.us L5 (DOD): https://dod-graph.microsoft.us |
| Microsoft Graph Germany | https://graph.microsoft.de |
| Microsoft Graph China | https://microsoftgraph.chinacloudapi.cn |

Please note that each National Cloud Deployment also has its own corresponding application registration portal and OAuth endpoints, both of which are completely separate from those used for/by the global Microsoft Graph service. Applications that wish to work with a specific National Cloud Deployment must use that National Cloud Deployment's app registration portal and OAuth endpoints to register and authenticate in order for the component to successfully communicate using the National Cloud Deployment-specific endpoint. Refer to Microsoft's [National Cloud Authentication](https://docs.microsoft.com/en-us/azure/active-directory/develop/authentication-national-cloud) article for more information.

**FragmentSize**: The fragment size.This setting controls the fragment size, in bytes, to use while uploading files when [UseResumableUpload](#useresumableupload-property-sharepoint-component) is *true*. When [UploadFile](#uploadfile-method-sharepoint-component) is called the file will be fragmented into pieces of this size.

The default value is *10485760* (10MB).

The value must be a multiple of 327680 (320 KB), or the server may return an error after the final fragment of a file is uploaded.

**ListSitesParams**: Specifies the exact endpoint used by the ListSites method.The endpoint that is used when [ListSites](#listsites-method-sharepoint-component) is called is described by the [ListSitesParams](#ListSitesParams) configuration setting. The endpoint is made up of the base url and the configuration setting like below:

*/sites/{ListSitesParams}*

The exact functionality of the certain endpoints depends on the type of scopes that the application has authenticated with. If the application is using delegated permissions (authenticated as user) then the method can only list the sites that the user has access to. If the application is using application permissions (authenticated as application) then the method can list all the sites available in the domain.

By default, the [ListSitesParams](#ListSitesParams) configuration setting is set to make a search endpoint call using the '*' character. This is to allow the [ListSites](#listsites-method-sharepoint-component) method to be used by both the delegated and application permissions as the base "List Sites" endpoint is not supported for delegated permissions. However, the "Search All" endpoint does not always contains all of the sites that are accessible by the authenticated entity. [ListSitesParams](#ListSitesParams) can be set to the following to change behavior of the [ListSites](#listsites-method-sharepoint-component) method.

| Endpoint | Parameter |
| --- | --- |
| List Sites (Application Only) | "" |
| Search All (Default) | "?search=*" |
| Search Keyword | "?search={Search Term}" |
| List Subsites | "/{SiteId}/sites" |

**MaxResults**: The maximum number of results to return.This setting is used to specify the maximum number of results that should be returned when calling [ListResources](#listresources-method-sharepoint-component) or [ListChanges](#listchanges-method-sharepoint-component). If there are more items than can be returned, the results will be paged and the appropriate "Marker" property populated.

The default is -1, which causes the server's default (200) to be used.

**ProgressAbsolute**: Whether the component should track transfer progress absolutely.This setting controls whether the component tracks upload and download progress absolutely or relatively, with regards to the values reported via the [Progress](#progress-event-sharepoint-component) event when an interrupted transfer is resumed.

If this setting is enabled (default), then when a transfer is interrupted and later resumed, the values reported by the [Progress](#progress-event-sharepoint-component) event will account for the data that was successfully transferred before the interruption.

If this setting is disabled, then the component will treat resumed transfers as "new" transfers, and the values reported by the [Progress](#progress-event-sharepoint-component) event will start at *0* rather than from the number of bytes already transferred.

Refer to the [Progress](#progress-event-sharepoint-component) event for more information.

**ProgressStep**: How often the progress event should be fired, in terms of percentage.This setting controls how often the component will fire the [Progress](#progress-event-sharepoint-component) event during an upload or download, in terms of percentage. Valid values are *0* to *99*, inclusive.

The default value, *1*, will cause the [Progress](#progress-event-sharepoint-component) event to fire each time the event's *PercentDone* parameter value increases by one percent. Setting this setting to *0* will cause the [Progress](#progress-event-sharepoint-component) event to fire *every* time data is transferred.

Note that the [Progress](#progress-event-sharepoint-component) event will *always* fire once at the beginning and end of a transfer, regardless of this setting's value. Also, if *PercentDone* cannot be calculated for a particular transfer (e.g., for downloads that use chunked transfer encoding), then the component will behave as if this setting were *0* for the duration of the transfer.

**RawRequest**: Returns the data that was sent to the server.This setting may be queried after calling any method that sends data to the server to obtain the request data that was transmitted. Such data may be useful for troubleshooting purposes.

**RawResponse**: Returns the data that was received from the server.This setting may be queried after calling any method that sends data to the server to obtain the response data that was received. Such data may be useful for troubleshooting purposes.

**RelativePath**: A resource path, relative to the currently selected folder Id, to use.When [RemoteId](#remoteid-property-sharepoint-component) is set to the Id of a remote folder resource, this setting can be used to specify a resource path that is relative to that folder. For example, setting [RemoteId](#remoteid-property-sharepoint-component) to *{dir2-Id}* and this setting to */dir3/test.txt* would accomplish the same thing as setting [RemotePath](#remotepath-property-sharepoint-component) to */dir1/dir2/dir3/test.txt*.

Keep in mind that the resource that the relative path points to must still be of the appropriate type (file or folder) depending on the method which will be called. Refer to [RemoteId](#remoteid-property-sharepoint-component) for more information.

**RenameIfExists**: Whether to rename newly-created resources in the event of a name conflict.This setting specifies whether the server should rename files uploaded with [UploadFile](#uploadfile-method-sharepoint-component) and folders created with [CreateFolder](#createfolder-method-sharepoint-component) if the desired name is already in use.

The name the server chooses will be always unique; it will append a number to the end of the original name (for files, before the extension). That number will be incremented until a unique name is found.

This setting is disabled by default. Note that this setting takes precedence over the [Overwrite](#overwrite-property-sharepoint-component) property if both are enabled when [UploadFile](#uploadfile-method-sharepoint-component) or [CreateFolder](#createfolder-method-sharepoint-component) is called.

**ResourceClientCreatedTime[i]**: The client-side creation timestamp of the specified resource.This setting can be queried to obtain the client-side creation timestamp for the resource at index *i*.

Timestamps are formatted according to ISO 8601 and are always in UTC time.

Valid values for *i* are from *0* to *(ResourceCount - 1)*.

**ResourceClientModifiedTime[i]**: The client-side last modified timestamp of the specified resource.This setting can be queried to obtain the client-side last modified timestamp for the resource at index *i*.

Timestamps are formatted according to ISO 8601 and are always in UTC time.

Valid values for *i* are from *0* to *(ResourceCount - 1)*.

**SitesDisplayName[i]**: The display name of the specified site.This setting can be queried to obtain the display name for the site at index *i*.

Valid values for *i* are from *0* to *(SiteCount - 1)*.

**TempPath**: The path to the directory where temporary files are created.This setting specifies the path where temporary files are created when downloading encrypted files. If not specified, the system's temporary directory is used. Refer to [DownloadTempFile](#DownloadTempFile) and [DownloadFile](#downloadfile-method-sharepoint-component) for more information.

**UploadExpDate**: The expiration of the resumable upload session.This setting holds expiration date of the resumable upload session represented by [ResumeURL](#resumeurl-property-sharepoint-component). It is populated after calling [PollUploadStatus](#polluploadstatus-method-sharepoint-component).

Timestamps are formatted according to ISO 8601 and are always in UTC time.

**UserId**: Sets the Id of the user to connect with.Specifies the Id to use when connecting to the server. Must be set when using Admin consented authorization flows.

**XChildCount**: The number of child elements of the current element.This configuration settings specifies the number of child attributes of the current element. The XChild configuration settings will be indexed from 0 to ([XChildCount](#XChildCount) - 1).

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XChildName[i]**: The name of the child element.This configuration setting provides the name of the i-th child element of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XChildXText[i]**: The inner text of the child element.This configuration setting provides the inner text of the i-th child element of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XElement**: The name of the current element.This configuration setting provides the name of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XParent**: The parent of the current element.This configuration setting provides the parent of the current element.

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XPath**: Provides a way to point to a specific element in the returned XML or JSON response.The [XPath](#XPath) setting allows you to point to specific elements in the XML or JSON response.

When [XPath](#XPath) is set to a valid path, [XElement](#XElement) points to the name of the element, with [XText](#XText), [XParent](#XParent), [XSubTree](#XSubTree), [XChildCount](#XChildCount), [XChildName\[i\]](#XChildName[i]), and [XChildXText\[i\]](#XChildXText[i]) providing other properties of the element.

XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the */* character, for example, */A/B/C/D*. An XPath can be absolute (i.e., it starts with */*), or it can be relative to the current [XPath](#XPath) location.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors, which proceed it in the overall XPath string:

| Accessor | Description |
| --- | --- |
| name | The first element with a particular name. Can be *. |
| [i] | The i-th element. |
| name[i] | The i-th element with a particular name. |
| [last()] | The last element. |
| [last()-i] | The element i before the last element. |
| name[@attrname="attrvalue"] | The first element with a particular name that contains the specified attribute-value pair. Supports single and double quotes. (XML Only) |
| . | The current element. |
| .. | The parent element. |

 NOTE: XPath indices are *1-based*.

For example, assume the following XML and JSON responses.

XML:

```text
<firstlevel>
  <one>value</one>
  <two>
    <item>first</item>
    <item>second</item>
  </two>
  <three>value three</three>
</firstlevel>
```

JSON:

```text
{
  "firstlevel": {
    "one": "value",
    "two": ["first", "second"],
    "three": "value three"
  }
}
```

The following are examples of valid XPaths for these responses:

| Description | XML XPath | JSON XPath |
| --- | --- | --- |
| Document root | / | /json |
| Specific element | /firstlevel/one | /json/firstlevel/one |
| i-th child | /firstlevel/two/item[2] | /json/firstlevel/two/[2] |

This list is not exhaustive, but it provides a general idea of the possibilities.

**XSubTree**: A snapshot of the current element in the document.This configuration setting provides the entirety of the current element (including its subelements).

The current element is specified through the [XPath](#XPath) configuration setting. This configuration setting is read-only.

**XText**: The text of the current element.This configuration setting provides the inner text of the current element.

The current element is specified in the [XPath](#XPath) configuration setting. This configuration setting is read-only.

### OAuth Config Settings

**OAuthAccessTokenExpiration**: The lifetime of the access token.This setting holds the lifetime of the access token in seconds. For instance the value *3600* indicates that the token will expire in one hour from the time it was generated.

**OAuthAuthorizationTokenType**: The type of access token returned.The applicable values include the following:

|  |  |
| --- | --- |
| Bearer (default) | When the access token returned by the server is a Bearer type, the authorization string returned by [Authorize](#authorize-method-sharepoint-component) will be in the format "Bearer access_token". This can be supplied as the value of the HTTP Authorization header. |

**OAuthAutomaticRefresh**: Whether or not to refresh an expired access token automatically.When this setting is set to *true* and the [Authorization](#authorization-property-sharepoint-component) property is not set, the component will automatically get a new access token if it has the necessary properties to do so without user interaction.

For example, when using the Authorization Code grant type, the [RefreshToken](#OAuthSettings_f_RefreshToken) field should be set to a valid refresh token. When using the Client Credential grant type however, the component does not need any additional properties set as it can already get a new access token without user interaction.

**OAuthBrowserResponseTimeout**: Specifies the amount of time to wait for a response from the browser.This setting specifies the amount of time (in seconds) the component will wait for a response from the browser when requesting user authentication. The default value is *0*, meaning that the component will wait indefinitely.

**OAuthIncludeEmptyRedirectURI**: Whether an empty redirect_uri parameter is included in requests.This setting specifies whether *redirect_uri* is included in the request made by [Authorize](#authorize-method-sharepoint-component) if it is empty.

If set to *true* (default) the *redirect_uri* will be sent in all cases. If set to *false* the *redirect_uri* will only be sent if it has a value.

**OAuthJWTPayload**: The payload of the JWT access token if present.This configuration setting provides the payload section of a JWT access token if the access token is a JWT and the component is able to parse out the payload section. This setting only applies to **access tokens** that are returned from a service provider after successfully authorizing and authenticating with the service.

To parse the payload for specific claims, see [OAuthJWTXPath](#OAuthJWTXPath).

**OAuthJWTXChildCount**: The number of child elements of the current element.The number of child attributes of the current element. The OAuthJWTXChildCount configuration settings will be indexed from 0 to ([OAuthJWTXChildCount](#OAuthJWTXChildCount) - 1).

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OauthJWTXChildName[i]**: The name of the child element.Provides the name of the i'th child element of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXChildXText[i]**: The inner text of the child element.Provides the inner text of the i'th child element of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXElement**: The name of the current element.Provides the name of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OauthJWTXParent**: The parent of the current element.Provides the parent of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXPath**: Provides a way to point to a specific element in the returned payload of a JWT based access token.The [OAuthJWTXPath](#OAuthJWTXPath) setting allows you to point to specific claims within the payload of a JWT based access token.

XPath syntax is available for the payload of JWT based access tokens if available. An XPath is a series of one or more element accessors separated by the */* character, for example: */A/B/C/D*.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors which proceed it in the overall XPath string:

| Accessor | Description |
| --- | --- |
| name | The first element with a particular name. Can be *. |
| [i] | The i-th element. |
| name[i] | The i-th element with a particular name. |
| [last()] | The last element. |
| [last()-i] | The element i before the last element. |

 Here are some examples of valid XPaths and some common claims:

| Description | JSON XPath |
| --- | --- |
| Document root | /json |
| Specific element | /json/element_one |
| Username Claim (Microsoft Specific) | /json/preferred_username |
| Registered Application Name Claim (Microsoft Specific) | /json/app_displayname |

This is not an exhaustive list by any means, but should provide a general idea of the possibilities. To get the text of the specified element, see [OAuthJWTXText](#OAuthJWTXText).

**OAuthJWTXSubTree**: A snapshot of the current element in the document.Provides the entirety of the current element (including its sub-elements).

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthJWTXText**: The text of the current element.Provides the inner text of the current element.

The current element is specified in the [OAuthJWTXPath](#OAuthJWTXPath) configuration setting. This configuration setting is read-only.

**OAuthParamCount**: Specifies the number of additional parameters variables to include in the request.This setting can be used to add query string parameters to the outgoing request. One common use for this method would be to add the "state" parameter to the request, which can be used when the [ClientProfile](#OAuthSettings_f_ClientProfile) is cocpWeb to add user defined data. The authorization server will include the "state" parameter in the response and will be available in the post back to your server which will allow you to maintain state in your application. This is used in conjunction with OAuthParamName[i] and OAuthParamValue[i]. For instance:

```text
component.Config("OAuthParamCount=2");
component.Config("OAuthParamName[0]=myvar");
component.Config("OAuthParamValue[0]=myvalue");
component.Config("OAuthParamName[1]=testname");
component.Config("OAuthParamValue[1]=testvalue");
```

Additionally, this will also be updated to hold the parameters returned in the response.

```text
for (int i = 0; i < int.Parse(component.Config("OAuthParamCount")); i++)
{
  string name = component.Config("OAuthParamName[" + i + "]");
  string value = component.Config("OAuthParamValue[" + i + "]");
}
```

**OAuthParamName[i]**: Specifies the parameter name at the specified index.This setting can be used to retrieve or specify the parameter variable name at the index specified. See [OAuthParamCount](#OAuthParamCount) for details.

**OAuthParamValue[i]**: Specifies the parameter value at the specified index.This setting can be used to retrieve or specify the parameter variable value at the index specified. See [OAuthParamCount](#OAuthParamCount) for details.

**OAuthPasswordGrantUsername**: Used in the Resource Owner Password grant type.Used to set the username field when the [GrantType](#OAuthSettings_f_GrantType) is set to the password grant type and [Authorize](#authorize-method-sharepoint-component) is called.

**OAuthPKCEChallengeEncoding**: The PKCE code challenge method to use.This setting controls the PKCE code challenge method used when [OAuthUsePKCE](#OAuthUsePKCE) is set to *true*. Possible values are:

- 1 (Plain)
- 2 (S256/SHA256 - default)

**OAuthPKCEVerifier**: The PKCE verifier used to generate the challenge.This configuration setting when queried provides the PKCE verifier that is used to generate the PKCE challenge for the [Authorize](#authorize-method-sharepoint-component) method and the [WebAuthURL](#OAuthSettings_f_WebAuthURL) field when [OAuthUsePKCE](#OAuthUsePKCE) is set to true. When using the cocpWeb [ClientProfile](#OAuthSettings_f_ClientProfile), the configuration setting can be set instead to allow the authorization request to be made from a different instance than the authentication (token) request.

**OAuthResetData**: Determines if the Reset method applies to the OAuth settings.If set to *true* (default), the [Reset](#reset-method-sharepoint-component) method will reset the OAuth settings including any authorization fields like [AccessToken](#OAuthSettings_f_AccessToken) and [RefreshToken](#OAuthSettings_f_RefreshToken). This means the [Authorize](#authorize-method-sharepoint-component) method must be called again to get new authorization information. When set to *false*, the [Reset](#reset-method-sharepoint-component) method will **not** reset the [OAuth](#oauth-property-sharepoint-component) property and the OAuth* configuration settings. This allows for the component to be reset without having to get authorization again.

**OAuthReUseWebServer**: Determines if the same server instance is used between requests.If set to *true* (default), the same embedded web server instance will be used for multiple requests. If set to *false* the embedded web server will be created and destroyed on each call to [Authorize](#authorize-method-sharepoint-component)

**OAuthTransferredRequest**: The full OAuth request last sent by the client.This configuration setting returns the full OAuth request last sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET

```text
Gmail gmail = new Gmail();
gmail.Config("OAuthTransferredRequest=on");
gmail.Authorize();
Console.WriteLine(gmail.Config("OAuthTransferredRequest"));
```

 C++

```text
Gmail gmail;
gmail.Config("OAuthTransferredRequest=on");
gmail.Authorize();
printf("%s\r\n", gmail.Config("OAuthTransferredRequest"));
```

**OAuthUsePKCE**: Specifies if PKCE should be used.If set to *true* (default), Proof Key for Code Exchange (PKCE) defined by RFC 7636 will be used when performing authorization. This setting applies when using the Authorization Code [GrantType](#OAuthSettings_f_GrantType). The [OAuthPKCEChallengeEncoding](#OAuthPKCEChallengeEncoding) configuration setting can be used to control the code challenge method that will be used.

**OAuthWebServerActive**: Specifies and controls whether the embedded web server is active.The setting when queried will return the current state of the web server. If the webserver is active, it will return *"true"* and if it is inactive it will return *"false"*.

This setting can also be set to activate or deactivate the web server. Under normal circumstances, this would not be required as the component will automatically start and stop the web server when [Authorize](#authorize-method-sharepoint-component) is called. In certain cases, it is required to start the webserver before calling [Authorize](#authorize-method-sharepoint-component). For example, if the [ReturnURL](#OAuthSettings_f_ReturnURL) needs to be set to a relay server, then you will need to start the web server manually. Another example would be when the [OAuthReUseWebServer](#OAuthReUseWebServer) is set to true, the server will not be automatically stopped, and this configuration setting must be set to *"false"* to stop the embedded web server.

**OAuthWebServerCertStore**: The certificate with private key to use when SSL is enabled.The name of the certificate store used for the embedded web server's SSL.

The [OAuthWebServerCertStoreType](#OAuthWebServerCertStoreType) field specifies the type of the certificate store specified by [OAuthWebServerCertStore](#OAuthWebServerCertStore). If the store is password protected, specify the password in [OAuthWebServerCertStorePassword](#OAuthWebServerCertStorePassword).

[OAuthWebServerCertStore](#OAuthWebServerCertStore) is used in conjunction with the [OAuthWebServerCertSubject](#OAuthWebServerCertSubject) field in order to specify the certificate to be used during SSL.

 Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

|  |  |
| --- | --- |
| MY | A certificate store holding personal certificates with their associated private keys. |
| CA | Certifying authority certificates. |
| ROOT | Root certificates. |

When the certificate store type is *cstPFXFile*, this property must be set to the name of the file. When the type is *cstPFXBlob*, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Note: This is required when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerCertStorePassword**: The certificate with private key to use when SSL is enabled.If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

Note: This is only applicable when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerCertStoreType**: The certificate with private key to use when SSL is enabled.This specifies the type of certificate store. Possible values are:

|  |  |
| --- | --- |
| 0 | User - This is the default for Windows. This specifies that the certificate store is a certificate store owned by the current user. NOTE: This store type is not available in Java. |
| 1 | Machine - For Windows, this specifies that the certificate store is a machine store. NOTE: This store type is not available in Java. |
| 2 | PFXFile - The certificate store is the name of a PFX (PKCS12) file containing certificates. |
| 3 | PFXBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS12) format. |
| 4 | JKSFile - The certificate store is the name of a Java Key Store (JKS) file containing certificates. NOTE: This store type is available only in Java. |
| 5 | JKSBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. NOTE: This store type is available only in Java. |
| 6 | PEMKeyFile - The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate. |
| 7 | PEMKeyBlob - The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate. |
| 14 | PPKFile - The certificate store is the name of a file that contains a PPK (PuTTY Private Key). |
| 15 | PPKBlob - The certificate store is a string (binary) that contains a PPK (PuTTY Private Key). |
| 16 | XMLFile - The certificate store is the name of a file that contains a certificate in XML format. |
| 17 | XMLBlob - The certificate store is a string that contains a certificate in XML format. |

 Note: This is required when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerCertSubject**: The certificate with private key to use when SSL is enabled.The subject of the SSL certificate.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows:

| Field | Meaning |
| --- | --- |
| CN | Common Name. This is commonly a hostname like www.server.com. |
| O | Organization |
| OU | Organizational Unit |
| L | Locality |
| S | State |
| C | Country |
| E | Email Address |

If a field value contains a comma, it must be quoted.

Note: This is required when [OAuthWebServerSSLEnabled](#OAuthWebServerSSLEnabled) is set to *true*.

**OAuthWebServerFailedResponse**: The custom response that will be displayed to the user if authentication failed.When [Authorize](#authorize-method-sharepoint-component) is called the user will be redirected to the embedded web server upon completing authentication with the authorization server. If authentication failed, the HTML specified here will be sent to the user's browser.

**OAuthWebServerHost**: The hostname used by the embedded web server displayed in the ReturnURL.This setting specifies the hostname used by the embedded web server when [ClientProfile](#OAuthSettings_f_ClientProfile) is set to cocpApplication. This specifies the interface on which the embedded web server listens, and also the value displayed in the [ReturnURL](#OAuthSettings_f_ReturnURL). This should be set to the hostname only, not the full URL.

The default value is *localhost*.

**OAuthWebServerPort**: The local port on which the embedded web server listens.This property specifies the port on which the embedded web server listens. Setting this to *0* (default) enables the system to choose a port at random. The chosen port will be returned when this setting is queried after the server has started listening.This is only applicable when using the embedded web server.

**OAuthWebServerResponse**: The custom response that will be displayed to the user.When [Authorize](#authorize-method-sharepoint-component) is called the user will be redirected to the embedded web server upon completing authentication with the authorization server. This setting allows you to specify the HTML that will be sent to the user's browser.

**OAuthWebServerSSLEnabled**: Whether the web server requires SSL connections.This setting specifies whether the embedded web server will use SSL. If set to *True* OAuthWebServerCert* configs are required and the server will only accept SSL connections. If set to *False* only plaintext connects are supported.

### HTTP Config Settings

**AcceptEncoding**: Used to tell the server which types of content encodings the client supports.When [AllowHTTPCompression](#AllowHTTPCompression) is True, the component adds an *Accept-Encoding* header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the *Accept-Encoding* header. NOTE: The component only supports gzip and deflate decompression algorithms.

**AllowHTTPCompression**: This property enables HTTP compression for receiving data.This configuration setting enables HTTP compression for receiving data. When set to True (default), the component will accept compressed data. It then will uncompress the data it has received. The component will handle data compressed by both gzip and deflate compression algorithms.

When True, the component adds an *Accept-Encoding* header to the outgoing request. The value for this header can be controlled by the [AcceptEncoding](#AcceptEncoding) configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

**AllowHTTPFallback**: Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the component will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the component throws an exception if the server does not support HTTP/2.

The default value is True.

**AllowNTLMFallback**: Whether to allow fallback from Negotiate to NTLM when authenticating.This configuration setting applies only when AuthScheme is set to Negotiate. If set to True, the component will automatically use New Technology LAN Manager (NTLM) if the server does not support Negotiate authentication. NOTE: The server must indicate that it supports NTLM authentication through the WWW-Authenticate header for the fallback from Negotiate to NTLM to take place. The default value is False.

**Append**: Whether to append data to LocalFile.This configuration setting determines whether data will be appended when writing to [LocalFile](#localfile-property-sharepoint-component). When set to True, downloaded data will be appended to [LocalFile](#localfile-property-sharepoint-component). This may be used in conjunction with [Range](#range-property-sharepoint-component) to resume a failed download. This is applicable only when [LocalFile](#localfile-property-sharepoint-component) is set. The default value is False.

**Authorization**: The Authorization string to be sent to the server.If the [Authorization](#Authorization) property contains a nonempty string, an *Authorization* HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP component can be extended with other security schemes in addition to the authorization schemes already implemented by the component.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the [Authorization](#authorization-property-sharepoint-component) property in the form "Basic [encoded-user-password]".

**BytesTransferred**: Contains the number of bytes transferred in the response data.This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the [Transfer](#transfer-event-sharepoint-component) event, by [BytesTransferred](#BytesTransferred).

**ChunkSize**: Specifies the chunk size in bytes when using chunked encoding.This is applicable only when [UseChunkedEncoding](#UseChunkedEncoding) is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

**CompressHTTPRequest**: Set to true to compress the body of a PUT or POST request.If set to True, the body of a *PUT* or *POST* request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

**EncodeURL**: If set to True the URL will be encoded by the component.If set to True, the URL passed to the component will be URL encoded. The default value is False.

**FollowRedirects**: Determines what happens when the server issues a redirect.This option determines what happens when the server issues a redirect. Normally, the component returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the component throws an exception.

**Note:** Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for *GET* or *HEAD* requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the component throws an exception instead.

Following are the valid options:

- 0 - Never
- 1 - Always
- 2 - Same Scheme

**GetOn302Redirect**: If set to True the component will perform a GET on the new location.The default value is False. If set to True, the component will perform a *GET* on the new location. Otherwise, it will use the same HTTP method again.

**HTTP2HeadersWithoutIndexing**: HTTP2 headers that should not update the dynamic header table with incremental indexing.HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

**HTTPVersion**: The version of HTTP used by the component.This property specifies the HTTP version used by the component. Possible values are as follows:

- "1.0"
- "1.1" (default)
- "2.0"
- "3.0"

When using HTTP/2 ("2.0") or HTTP/3 ("3.0"), additional restrictions apply. Please see the following notes for details.

**HTTP/2 Notes**

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the component will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check [NegotiatedHTTPVersion](#NegotiatedHTTPVersion) after calling a method. The [AllowHTTPFallback](#AllowHTTPFallback) setting controls whether this behavior is allowed (default) or disallowed.

HTTP/2 is supported on all versions of Windows. If the Windows version is an earlier version than Windows 8.1/Windows Server 2012 R2, the internal security implementation will be used. If the Windows version is Window 8.1/Windows Server 2012 R2 or later, the system security libraries will be used by default.

**HTTP/3 Notes**

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

**IfModifiedSince**: A date determining the maximum age of the desired document.If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example:

```text
Sat, 29 Oct 2017 19:43:31 GMT.
```

**KeepAlive**: Determines whether the HTTP connection is closed after completion of the request.If *true*, the component will not send the *Connection: Close* header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. NOTE: Not all servers support persistent connections. If *false*, the connection will be closed immediately after the server response is received.

 The default value for [KeepAlive](#KeepAlive) is *false*.

**KerberosSPN**: The Service Principal Name for the Kerberos Domain Controller.If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

**LogLevel**: The level of detail that is logged.This configuration setting controls the level of detail that is logged through the [Log](#log-event-sharepoint-component) event. Possible values are as follows:

|  |  |
| --- | --- |
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

**MaxHeaders**: Instructs component to save the amount of headers specified that are returned by the server after a Header event has been fired.This configuration setting should be set when the TransferredHeaders collection is to be populated when a [Header](#header-event-sharepoint-component) event has been fired. This value represents the number of headers that are to be saved in the collection.

To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.

**MaxHTTPCookies**: Instructs component to save the amount of cookies specified that are returned by the server when a SetCookie event is fired.This configuration setting should be set when populating the Cookies collection as a result of an HTTP request. This value represents the number of cookies that are to be saved in the collection.

To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.

**MaxRedirectAttempts**: Limits the number of redirects that are followed in a request.When FollowRedirects is set to any value other than frNever, the component will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

**NegotiatedHTTPVersion**: The negotiated HTTP version.This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the component will fall back to using "1.1" automatically. This setting will indicate which version was used.

**OtherHeaders**: Other headers as determined by the user (optional).This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF (*"\r\n"*) .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the component beyond what is provided.

**ProxyAuthorization**: The authorization string to be sent to the proxy server.This is similar to the [Authorization](#Authorization) configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a *Proxy-Authorization* HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If [User](#Proxy_f_User) and [Password](#Proxy_f_Password) are specified, this value is calculated using the algorithm specified by [AuthScheme](#Proxy_f_AuthScheme).

**ProxyAuthScheme**: The authorization scheme to be used for the proxy.This configuration setting is provided for use by components that do not directly expose Proxy properties.

**ProxyPassword**: A password if authentication is to be used for the proxy.This configuration setting is provided for use by components that do not directly expose Proxy properties.

**ProxyPort**: Port for the proxy server (default 80).This configuration setting is provided for use by components that do not directly expose Proxy properties.

**ProxyServer**: Name or IP address of a proxy server (optional).This configuration setting is provided for use by components that do not directly expose Proxy properties.

**ProxyUser**: A user name if authentication is to be used for the proxy.This configuration setting is provided for use by components that do not directly expose Proxy properties.

**SentHeaders**: The full set of headers as sent by the client.This configuration setting returns the complete set of raw headers as sent by the client.

**StatusCode**: The status code of the last response from the server.This configuration setting contains the result code of the last response from the server.

**StatusLine**: The first line of the last response from the server.This setting contains the first line of the last response from the server. The format of the line will be *[HTTP version] [Result Code] [Description]*.

**TransferredData**: The contents of the last response from the server.This configuration setting contains the contents of the last response from the server.

**TransferredDataLimit**: The maximum number of incoming bytes to be stored by the component.If [TransferredDataLimit](#TransferredDataLimit) is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the component.

**TransferredHeaders**: The full set of headers as received from the server.This configuration setting returns the complete set of raw headers as received from the server.

**TransferredRequest**: The full request as sent by the client.This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

 .NET

```text
Http http = new Http();
http.Config("TransferredRequest=on");
http.PostData = "body";
http.Post("http://someserver.com");
Console.WriteLine(http.Config("TransferredRequest"));
```

 C++

```text
HTTP http;
http.Config("TransferredRequest=on");
http.SetPostData("body", 5);
http.Post("http://someserver.com");
printf("%s\r\n", http.Config("TransferredRequest"));
```

**UseChunkedEncoding**: Enables or Disables HTTP chunked encoding for transfers.If [UseChunkedEncoding](#UseChunkedEncoding) is set to True, the component will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the component will not use HTTP-chunked encoding. The default value is False.

NOTE: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

**UseIDNs**: Whether to encode hostnames to internationalized domain names.This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified.

**UsePlatformDeflate**: Whether to use the platform implementation to decompress compressed responses.This configuration setting specifies whether the platform's deflate-algorithm implementation is used to decompress responses that use compression. If set to *True* (default), the platform implementation is used. If set to *False*, an internal implementation is used.

**UsePlatformHTTPClient**: Whether or not to use the platform HTTP client.When using this configuration setting, if True, the component will use the default HTTP client for the platform (*URLConnection* in Java, *WebRequest* in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments in which direct access to sockets is limited or not allowed (e.g., in the Google AppEngine).

**UseProxyAutoConfigURL**: Whether to use a Proxy auto-config file when attempting a connection.This configuration specifies whether the component will attempt to use the Proxy auto-config URL when establishing a connection and [AutoDetect](#Proxy_f_AutoDetect) is set to *True*.

When *True* (default), the component will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

**UserAgent**: Information about the user agent (browser).This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

### TCPClient Config Settings

**CloseStreamAfterTransfer**: If true, the component will close the upload or download stream after the transfer.This configuration setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. To keep streams open after the transfer of data, set this to False. The default value is True.

**ConnectionTimeout**: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the component will use [Timeout](#timeout-property-sharepoint-component) for establishing a connection and transmitting/receiving data.

**FirewallAutoDetect**: Tells the component whether or not to automatically detect and use firewall system settings, if available.This configuration setting is provided for use by components that do not directly expose Firewall properties.

**FirewallHost**: Name or IP address of firewall (optional).If a [FirewallHost](#FirewallHost) is given, requested connections will be authenticated through the specified firewall when connecting.

If the [FirewallHost](#FirewallHost) setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the [FirewallHost](#FirewallHost) setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

**FirewallHTTPVersion**: The HTTP version to be used when connecting through a tunneling proxy.When [FirewallType](#FirewallType) is set to a tunneling proxy, this setting dictates which HTTP version is used when connecting.

**FirewallListener**: If true, the component binds to a SOCKS firewall as a server (TCPClient only).This entry is for TCPClient only and does not work for other components that descend from TCPClient.

If this entry is set, the component acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

**FirewallPassword**: Password to be used if authentication is to be used when connecting through the firewall.If [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the given firewall. If the authentication fails, the component throws an exception.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

**FirewallPort**: The TCP port for the FirewallHost;.The [FirewallPort](#FirewallPort) is set automatically when [FirewallType](#FirewallType) is set to a valid value.

NOTE: This configuration setting is provided for use by components that do not directly expose Firewall properties.

**FirewallType**: Determines the type of firewall to connect through.Possible values are as follows:

|  |  |
| --- | --- |
| 0 | No firewall (default setting). |
| 1 | Connect through a tunneling proxy. [FirewallPort](#FirewallPort) is set to 80. |
| 2 | Connect through a SOCKS4 Proxy. [FirewallPort](#FirewallPort) is set to 1080. |
| 3 | Connect through a SOCKS5 Proxy. [FirewallPort](#FirewallPort) is set to 1080. |
| 10 | Connect through a SOCKS4A Proxy. [FirewallPort](#FirewallPort) is set to 1080. |

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

**FirewallUser**: A user name if authentication is to be used connecting through a firewall.If the [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the Firewall. If the authentication fails, the component throws an exception.

NOTE: This setting is provided for use by components that do not directly expose Firewall properties.

**KeepAliveInterval**: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by [KeepAliveTime](#KeepAliveTime). If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

NOTE: This value is not applicable in macOS.

**KeepAliveTime**: The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

**Linger**: When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if [LingerTime](#LingerTime) is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if [LingerTime](#LingerTime) is a positive value, the system will attempt to send pending data until the specified [LingerTime](#LingerTime) is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the component returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

**LingerTime**: Time in seconds to have the connection linger. LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

**LocalHost**: The name of the local host through which connections are initiated or accepted. The [LocalHost](#localhost-property-sharepoint-component) setting contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component is connected, the [LocalHost](#localhost-property-sharepoint-component) setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

**LocalPort**: The port in the local host where the component binds. This configuration setting must be set before a connection is attempted. It instructs the component to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

**MaxLineLength**: The maximum amount of data to accumulate when no EOL is found.[MaxLineLength](#MaxLineLength) is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before [MaxLineLength](#MaxLineLength) bytes are received, the DataIn event is fired with the *EOL* parameter set to True, and the buffer is reset.

If no EOL is found, and [MaxLineLength](#MaxLineLength) bytes are accumulated in the buffer, the DataIn event is fired with the *EOL* parameter set to False, and the buffer is reset.

The minimum value for [MaxLineLength](#MaxLineLength) is 256 bytes. The default value is 2048 bytes.

**MaxTransferRate**: The transfer rate limit in bytes per second.This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

**ProxyExceptionsList**: A semicolon separated list of hosts and IPs to bypass when using a proxy.This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

*www.google.com;www.example.com*

**TCPKeepAlive**: Determines whether or not the keep alive socket option is enabled.If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set [KeepAliveTime](#KeepAliveTime) and [KeepAliveInterval](#KeepAliveInterval) to configure the timing of the keep-alive packets.

NOTE: This value is not applicable in Java.

**TcpNoDelay**: Whether or not to delay when sending packets. When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

**UseIPv6**: Whether to use IPv6.When set to *0* (default), the component will use IPv4 exclusively. When set to *1*, the component will use IPv6 exclusively. To instruct the component to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to *2*. The default value is *0*. Possible values are as follows:

|  |  |
| --- | --- |
| 0 | IPv4 only |
| 1 | IPv6 only |
| 2 | IPv6 with IPv4 fallback |

**UseNTLMv2**: Whether to use NTLM V2.When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is True and NTLM V2 will be used. Set this to False to use NTLM V1.

### SSL Config Settings

**CACertFilePaths**: The paths to CA certificate files when using Mono on Unix/Linux.This configuration setting specifies the paths on disk to certificate authority (CA) certificate files when using Mono on Unix/Linux. It is not applicable in any other circumstances.

The value is formatted as a list of paths separated by semicolons. The component will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is as follows:

*/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem*

**LogSSLPackets**: Controls whether SSL packets are logged when using the internal security API.When [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal*, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is *False*, as it is useful only for debugging purposes.

When enabled, SSL packet logs are output using the [SSLStatus](#sslstatus-event-sharepoint-component) event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Platform*.

**ReuseSSLSession**: Determines if the SSL session is reused.

If set to True, the component will reuse the context if and only if the following criteria are met:

- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the component is the same.

**SSLCACerts**: A newline separated list of CA certificates to be included when performing an SSL handshake.When [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal*, this configuration setting specifies one or more CA certificates to be included with the [SSLCert](#sslcert-property-sharepoint-component) property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

```text
-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----
```

**SSLCheckCRL**: Whether to check the Certificate Revocation List for the server certificate.This configuration setting specifies whether the component will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the component will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The component will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the component throws an exception.

When set to 0 (default), the CRL check will not be performed by the component. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

**SSLCheckOCSP**: Whether to use OCSP to check the status of the server certificate.This configuration setting specifies whether the component will use OCSP to check the validity of the server certificate. If set to 1 or 2, the component will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The component will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the component throws an exception.

When set to 0 (default), the component will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

**SSLCipherStrength**: The minimum cipher strength used for bulk encryption. This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

NOTE: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the [SSLStatus](#sslstatus-event-sharepoint-component) event.

Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, [SSLCipherStrength](#SSLCipherStrength) is currently not supported. This functionality is instead made available through the [OpenSSLCipherList](#OpenSSLCipherList) configuration setting.

**SSLClientCACerts**: A newline separated list of CA certificates to use during SSL client certificate validation.This configuration setting is only applicable to server components (e.g., TCPServer) see [SSLServerCACerts](#SSLServerCACerts) for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when SSLAuthenticateClients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

```text

```

**SSLEnabledCipherSuites**: The cipher suite to be used in an SSL negotiation.This configuration setting enables the cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the component will pick all of the supported cipher suites. If [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Platform* include the following:

```text
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=CALG_AES_256");
obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES");
```

 Possible values when [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Platform* include the following:

- CALG_3DES

When TLS 1.3 is negotiated (see [SSLEnabledProtocols](#SSLEnabledProtocols)), only the following cipher suites are supported:

- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256

[SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is used together with [SSLCipherStrength](#SSLCipherStrength).

**SSLEnabledProtocols**: Used to enable/disable the supported security protocols.This configuration setting is used to enable or disable the supported security protocols.

Not all supported protocols are enabled by default. The default value is *4032* for client components, and *3072* for server components. To specify a combination of enabled protocol versions set this config to the binary *OR* of one or more of the following values:

|  |  |
| --- | --- |
| TLS1.3 | 12288 (Hex 3000) |
| TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
| TLS1.1 | 768 (Hex 300) (Default - Client) |
| TLS1 | 192 (Hex C0) (Default - Client) |
| SSL3 | 48 (Hex 30) |
| SSL2 | 12 (Hex 0C) |

Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.

**SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:**

By default when TLS 1.3 is enabled, the component will first try to use the platform TLS 1.3 implementation when the [SSLProvider](#sslprovider-property-sharepoint-component) is set to Automatic for all editions. If the platform TLS 1.3 implementation is not available, the internal implementation will be used.

In editions that are designed to run on Windows, [SSLProvider](#sslprovider-property-sharepoint-component) can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to *1* (Platform provider), please be aware of the following notes:

- The platform provider is available only on Windows 11/Windows Server 2022 and up.
- [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) and other similar SSL configuration settings are not supported.
- If [SSLEnabledProtocols](#SSLEnabledProtocols) includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

**SSLEnabledProtocols: SSL2 and SSL3 Notes: **

SSL 2.0 and 3.0 are not supported by the component when the [SSLProvider](#sslprovider-property-sharepoint-component) is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and [SSLProvider](#sslprovider-property-sharepoint-component) needs to be set to platform.

**SSLEnableRenegotiation**: Whether the renegotiation_info SSL extension is supported.This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is *false* by default, but it can be set to *true* to enable the extension.

This configuration setting is applicable only when [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal*.

**SSLIncludeCertChain**: Whether the entire certificate chain is included in the SSLServerAuthentication event.This configuration setting specifies whether the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-sharepoint-component) event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-sharepoint-component) event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the [SSLServerAuthentication](#sslserverauthentication-event-sharepoint-component) event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal* this value is automatically set to *true*. This is needed for proper validation when using the internal provider.

**SSLKeyLogFile**: The location of a file where per-session secrets are written for debugging purposes.This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the component will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the component will only append, it will not overwrite previous values.

NOTE: This configuration setting is applicable only when [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal*.

**SSLNegotiatedCipher**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedCipher[connId]");
```

**SSLNegotiatedCipherStrength**: Returns the negotiated cipher suite strength.This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedCipherStrength[connId]");
```

**SSLNegotiatedCipherSuite**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedCipherSuite[connId]");
```

**SSLNegotiatedKeyExchange**: Returns the negotiated key exchange algorithm.This configuration setting returns the key exchange algorithm negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedKeyExchange[connId]");
```

**SSLNegotiatedKeyExchangeStrength**: Returns the negotiated key exchange algorithm strength.This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedKeyExchangeStrength[connId]");
```

**SSLNegotiatedVersion**: Returns the negotiated protocol version.This configuration setting returns the protocol version negotiated during the SSL handshake.

NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

```csharp
server.Config("SSLNegotiatedVersion[connId]");
```

**SSLSecurityFlags**: Flags that control certificate verification.The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions:

|  |  |
| --- | --- |
| 0x00000001 | Ignore time validity status of certificate. |
| 0x00000002 | Ignore time validity status of CTL. |
| 0x00000004 | Ignore non-nested certificate times. |
| 0x00000010 | Allow unknown certificate authority. |
| 0x00000020 | Ignore wrong certificate usage. |
| 0x00000100 | Ignore unknown certificate revocation status. |
| 0x00000200 | Ignore unknown CTL signer revocation status. |
| 0x00000400 | Ignore unknown certificate authority revocation status. |
| 0x00000800 | Ignore unknown root revocation status. |
| 0x00008000 | Allow test root certificate. |
| 0x00004000 | Trust test root certificate. |
| 0x80000000 | Ignore non-matching CN (certificate CN non-matching server name). |

This functionality is currently not available in Java or when the provider is OpenSSL.

**SSLServerCACerts**: A newline separated list of CA certificates to use during SSL server certificate validation.This configuration setting is only used by client components (e.g., TCPClient) see [SSLClientCACerts](#SSLClientCACerts) for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

```text
-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

... Root Cert...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----
```

**TLS12SignatureAlgorithms**: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.This configuration setting specifies the allowed server certificate signature algorithms when [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal* and [SSLEnabledProtocols](#SSLEnabledProtocols) is set to allow TLS 1.2.

When specified the component will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the component throws an exception.

The format of this value is a comma-separated list of hash-signature combinations. For instance:

```csharp
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
```

 The default value for this configuration setting is *sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa*.

To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

**TLS12SupportedGroups**: The supported groups for ECC.This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC.

The default value is *ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1*.

When using TLS 1.2 and [SSLProvider](#sslprovider-property-sharepoint-component) is set to *Internal*, the values refer to the supported groups for ECC. The following values are supported:

- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)

**TLS13KeyShareGroups**: The groups for which to pregenerate key shares.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.

NOTE: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.

In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.

The default value is *ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072*

The values are ordered from most preferred to least preferred. The following values are supported:

- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1"
- "ffdhe_2048" (default)
- "ffdhe_3072" (default)
- "ffdhe_4096"
- "ffdhe_6144"
- "ffdhe_8192"

**TLS13SignatureAlgorithms**: The allowed certificate signature algorithms.This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following:

- "ed25519" (default)
- "ed448" (default)
- "ecdsa_secp256r1_sha256" (default)
- "ecdsa_secp384r1_sha384" (default)
- "ecdsa_secp521r1_sha512" (default)
- "rsa_pkcs1_sha256" (default)
- "rsa_pkcs1_sha384" (default)
- "rsa_pkcs1_sha512" (default)
- "rsa_pss_sha256" (default)
- "rsa_pss_sha384" (default)
- "rsa_pss_sha512" (default)

 The default value is *rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448*. This configuration setting is applicable only when [SSLEnabledProtocols](#SSLEnabledProtocols) includes TLS 1.3.

**TLS13SupportedGroups**: The supported groups for (EC)DHE key exchange.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so.

The default value is *ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192,mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768*

The values are ordered from most preferred to least preferred. The following values are supported:

- "ecdhe_x25519" (default)
- "ecdhe_x448" (default)
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
- "ffdhe_2048" (default)
- "ffdhe_3072" (default)
- "ffdhe_4096" (default)
- "ffdhe_6144" (default)
- "ffdhe_8192" (default)
- "mlkem_512" (default)
- "mlkem_768" (default)
- "mlkem_1024" (default)
- "x25519_mlkem_768" (default)
- "secp256r1_mlkem_768" (default)

Post-quantum algorithms (*mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768*) in our components rely on the operating system's underlying cryptographic primitives. The following platforms are currently supported:

-  Windows Server 2025
-  Windows 11 24H2
-  Windows 11 25H2

### Socket Config Settings

**AbsoluteTimeout**: Determines whether timeouts are inactivity timeouts or absolute timeouts.If [AbsoluteTimeout](#AbsoluteTimeout) is set to True, any method that does not complete within [Timeout](#timeout-property-sharepoint-component) seconds will be aborted. By default, *AbsoluteTimeout* is False, and the timeout is an inactivity timeout.

NOTE: This option is not valid for User Datagram Protocol (UDP) ports.

**FirewallData**: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

**InBufferSize**: The size in bytes of the incoming queue of the socket.This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the *InBufferSize* setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the *InBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small.

**OutBufferSize**: The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the *OutBufferSize* setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the *OutBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small.

### Base Config Settings

**BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build.

**GUIAvailable**: Whether or not a message loop is available for processing events.In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting [GUIAvailable](#GUIAvailable) to *false* will ensure that the component does not attempt to process external events.

**LicenseInfo**: Information about the current license.When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

- Product: The product the license is for.
- Product Key: The key the license was generated from.
- License Source: Where the license was found (e.g., RuntimeLicense, License File).
- License Type: The type of license installed (e.g., Royalty Free, Single Server).
- Last Valid Build: The last valid build number for which the license will work.

**MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*.

**UseFIPSCompliantAPI**: Tells the component whether or not to use FIPS certified APIs.When set to *true*, the component will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the *UseFIPSCompliantAPI* configuration setting to *true*. This is a static setting that applies to all instances of all components of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the [FIPS 140-2 Compliance](https://www.nsoftware.com/kb/articles/fips.rst) article.

NOTE: This setting is applicable only on Windows.

NOTE: Enabling FIPS compliance requires a special license; please contact [sales@nsoftware.com](mailto:sales@nsoftware.com) for details.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the component will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to *true*.

Setting this configuration setting to *true* tells the component to use the internal implementation instead of using the system security libraries.

 On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default.

NOTE: This setting is static. The value set is applicable to all components used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
