# Struct cloudmail::Office365

The Office365 struct provides an easy way to manage sending and receiving mail in Microsoft 365. The struct also includes support for creating, listing, and managing contacts.

## Syntax

```text
cloudmail::Office365
```

## Remarks

This struct provides an easy to use interface for Office365 using the Microsoft Graph API v1.0. To use the struct, first set the [authorization](#authorization-property-office365-struct) property to a valid OAuth token. The Office365 struct can be used for sending or creating new messages; retrieving, moving, or copying existing messages; creating, deleting, or copying folders; and several other functionalities supported by the Microsoft Graph API.

This struct requires authentication via OAuth 2.0. First, perform OAuth authentication using the o_auth property to set the appropriate fields for the chosen [o_auth_client_profile](#o_auth_client_profile-property-office365-struct) and [o_auth_grant_type](#o_auth_grant_type-property-office365-struct).

The struct has the following defaults:

|  |  |
| --- | --- |
| 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 mail.readwrite mail.send contacts.readwrite user.read" |

Additionally, depending on how the application is registered (e.g. Multi-tenant) and what [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) is selected (e.g. Client Credentials and Password), it may be required to use the tenant ID rather than "common" in the [o_auth_server_auth_url](#o_auth_server_auth_url-property-office365-struct) and [o_auth_server_token_url](#o_auth_server_token_url-property-office365-struct) properties. 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 [o_auth_client_profile](#o_auth_client_profile-property-office365-struct) and [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) values that are supported by this struct. 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 struct. 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-office365-struct) method should be called. If the authorization and authentication was successful, then the [o_auth_access_token](#o_auth_access_token-property-office365-struct) property will be populated. Additionally, if a *refresh token* was provided the [o_auth_refresh_token](#o_auth_refresh_token-property-office365-struct) property will be populated as well. These values of the fields are for informational purposes. The struct will also cache these tokens along with when the [o_auth_access_token](#o_auth_access_token-property-office365-struct) will be expired. When a method that makes requests to the service provider is called or the [authorize](#authorize-method-office365-struct) method is called the struct will automatically check to see if the *access token* is expired. If it is, it will then automatically try to get a new [o_auth_access_token](#o_auth_access_token-property-office365-struct). If the [authorize](#authorize-method-office365-struct) method was not used and user interaction would be required, the struct will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) property. To force the component to only check the *access token* when the [authorize](#authorize-method-office365-struct) method is called, the [OAuthAutomaticRefresh](#OAuthAutomaticRefresh) configuration setting can be set to false.

A brief description of the supported values for the [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) property are below. For more information, see the service documentation.

**Authorization Code**

When using the *Authorization Code* grant type, the struct will use an *authorization code* to get an *access token*. For this [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) the struct expects a [o_auth_client_id](#o_auth_client_id-property-office365-struct), [o_auth_client_secret](#o_auth_client_secret-property-office365-struct), [o_auth_server_auth_url](#o_auth_server_auth_url-property-office365-struct), and [o_auth_server_token_url](#o_auth_server_token_url-property-office365-struct) to be set. When the [authorize](#authorize-method-office365-struct) 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 struct will parse the *authorization code*, setting the [o_auth_authorization_code](#o_auth_authorization_code-property-office365-struct) property, from the redirect. Immediately, the struct 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 [o_auth_refresh_token](#o_auth_refresh_token-property-office365-struct) property is set, or a *refresh token* is cached, then the struct will not launch the browser and use the *refresh token* in its request to the token server instead of an *authorization code*.

**Example: **

```csharp
Office365 office365 = new Office365();

office365.OAuth.ClientProfile = CloudOAuthClientProfiles.cocpApplication;
office365.OAuth.GrantType = OAuthSettingsGrantTypes.cogtAuthorizationCode;
office365.OAuth.ClientId = CLIENT_ID;
office365.OAuth.ClientSecret = CLIENT_SECRET;

office365.Authorize();
```

**Client Credentials**

When using the *Client Credentials* grant type, the struct will act as a service instead of authorizing and authenticating as a user. This allows for the struct 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 [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) the struct expects a [o_auth_client_id](#o_auth_client_id-property-office365-struct), [o_auth_client_secret](#o_auth_client_secret-property-office365-struct), and [o_auth_server_token_url](#o_auth_server_token_url-property-office365-struct) to be set. When the [authorize](#authorize-method-office365-struct) 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 struct will request the authorization server to get an *access token*. For this [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) the struct expects a [o_auth_client_id](#o_auth_client_id-property-office365-struct), [o_auth_client_secret](#o_auth_client_secret-property-office365-struct), and [o_auth_server_auth_url](#o_auth_server_auth_url-property-office365-struct) to be set. When the [authorize](#authorize-method-office365-struct) 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 struct 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 struct 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 struct will authenticate as the resource owner. This allows for the struct 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 [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) the struct requires [OAuthPasswordGrantUsername](#OAuthPasswordGrantUsername), [o_auth_client_secret](#o_auth_client_secret-property-office365-struct), and [o_auth_server_token_url](#o_auth_server_token_url-property-office365-struct) to be set. The [o_auth_client_secret](#o_auth_client_secret-property-office365-struct) should be set to the password of the account instead of a typical secret. In some cases, the [o_auth_client_id](#o_auth_client_id-property-office365-struct) also needs to be set. When the [authorize](#authorize-method-office365-struct) 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 struct to the Application profile and Authorization Code grant type except the struct 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 [o_auth_client_id](#o_auth_client_id-property-office365-struct), [o_auth_client_secret](#o_auth_client_secret-property-office365-struct), [o_auth_server_auth_url](#o_auth_server_auth_url-property-office365-struct), [o_auth_server_token_url](#o_auth_server_token_url-property-office365-struct), and the [o_auth_return_url](#o_auth_return_url-property-office365-struct) properties to be set. Before calling the [authorize](#authorize-method-office365-struct) method, the [o_auth_web_auth_url](#o_auth_web_auth_url-property-office365-struct) property 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 [o_auth_return_url](#o_auth_return_url-property-office365-struct) property. The [o_auth_return_url](#o_auth_return_url-property-office365-struct) property 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 [o_auth_authorization_code](#o_auth_authorization_code-property-office365-struct) property. Once that is set, the [authorize](#authorize-method-office365-struct) method can be called to exchange the *authorization code* for an *access token* and *refresh token* if provided. The struct will then cache these values like normal and use them to make requests. If the [o_auth_refresh_token](#o_auth_refresh_token-property-office365-struct) field is set, or a *refresh token* is cached, then the [authorize](#authorize-method-office365-struct) 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-office365-struct) property before attempting any operations. Setting the [authorization](#authorization-property-office365-struct) property will cause the struct to ignore the values set in the o_auth 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 user.read mail.readwrite mail.send mailboxsettings.readwrite user.readwrite Contacts.Read Contacts.ReadWrite";
oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode;

office365.Authorization = oauth.GetAuthorization();
```

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

### Sending Messages

There are two methods for sending new messages using the Office365 component. The [send_mail](#send_mail-method-office365-struct) method will send a message directly. Alternatively, you can create a message draft and then send an existing draft using the [send_draft](#send_draft-method-office365-struct) method. In both cases the properties of the new message are assigned through the Message properties ([message_subject](#message_subject-property-office365-struct), [message_body_content](#message_body_content-property-office365-struct), [message_cc](#message_cc-property-office365-struct), etc.).

**Sending a Message with SendDraft:**

```csharp
office365.MessageSubject = "Subject Text";
office365.MessageImportance = "Low";
office365.MessageBodyContentType = "TEXT";
office365.MessageBodyContent = "Body Text.";
office365.MessageTo = "email@example.com";

office365.CreateDraft(0, "");
string messageId = office365.MessageInfo[0].Id;

office365.SendDraft(messageId);
```

There are also methods for replying or forwarding messages using the Office365 component. The [reply](#reply-method-office365-struct), [reply_all](#reply_all-method-office365-struct), and [forward](#forward-method-office365-struct) method will send a reply or forward directly. Similarly, you can create a reply or forward draft and then send an existing draft using the [send_draft](#send_draft-method-office365-struct) method. Unlike creating a new message, only the direct methods use the Message properties ([message_subject](#message_subject-property-office365-struct), [message_body_content](#message_body_content-property-office365-struct), [message_cc](#message_cc-property-office365-struct), etc.). When using [create_draft](#create_draft-method-office365-struct), the draft must first be made then updated using the message_info properties and [update](#update-method-office365-struct) method.

**Sending a Reply with SendDraft:**

```csharp
//Create the reply draft
string originalMessageId = "Message ID";
office365.CreateDraft(1, oringialMessageId);

//Set the new draft MessageInfo fields with desired options
office365.MessageInfo[0].To = "email@example.com";
office365.MessageInfo[0].Subject = "Subject Text";
office365.MessageInfo[0].BodyContentType = "TEXT";
office365.MessageInfo[0].BodyContent = "Body Text";

//Update the draft
office365.Update(office365.MessageInfo[0].Id);

//Send the draft
office365.SendDraft(office365.MessageInfo[0].Id);
```

### Receiving Messages

Information about messages fetched by the component can be accessed through the message_info properties. message_info properties is populated when the [list_messages](#list_messages-method-office365-struct), [retrieve_message](#retrieve_message-method-office365-struct), [search](#search-method-office365-struct), or [list_changes](#list_changes-method-office365-struct) methods are called.

The [list_messages](#list_messages-method-office365-struct) and [list_changes](#list_changes-method-office365-struct) methods will respectively list the messages or changed messages in a folder specified by a *folderId*. To get the ID of a folder, folders can be traversed and read using the [list_folders](#list_folders-method-office365-struct) method and the folders properties.

**Listing Messages in a Folder:**

```csharp
// Get the folder ID
string folderId = "";

office365.ListFolders(""); // Lists the root child folders.

for (int i = 0; i < office365.Folders.Count; i++)
{
  if (office365.Folders[i].DisplayName.Equals("SpecificFolderName"))
  {
    folderId = office365.Folders[i].Id;
    break;
  }
}

// List folder messages
office365.ListMessages(folderId, "");
```

By default, the component will fetch one page of 100 messages when [list_messages](#list_messages-method-office365-struct) is called. If additional messages remain in the folder, the [list_messages_marker](#list_messages_marker-property-office365-struct) property will be populated. If [list_messages](#list_messages-method-office365-struct) is then called again on the same folder the next page of messages will be fetched. The example below populates message_info properties with all the messages in a particular folder.

```csharp
do {
  office365.ListMessages(folderId);
} while (office365.ListMessagesMarker.Length > 0);
```

The message page size may also be changed by using the [MessagePageSize](#MessagePageSize) configuration setting.

### Listing Contact Folders

To list the contact folders of a user use the [list_contact_folders](#list_contact_folders-method-office365-struct) method. It populates the contact_folders collection with the retrieved folders. For each retrieved folder the [on_contact_folder_list](#on_contact_folder_list-event-office365-struct) event is fired.

**Example (List All Contact Folders): **

```csharp
office365.ListContactFolders(); // List root folders.
foreach(OLContactFolder folder in office365.ContactFolders){
    folder.Id;              // Folder id
    folder.Name;            // Folder name
}
```

### Listing Contacts

Use the [list_contacts](#list_contacts-method-office365-struct) to populate the contacts collection with the the contacts that are in a specified folder. Providing an empty string as *folderId* retrieves the contacts from the default Contacts folder of the signed-in user. For each retrieved contact the [on_contact_list](#on_contact_list-event-office365-struct) event is fired.

**Example (List All Contacts in a Folder)**

```text
office365.ListContactFolders(""); //List root folders (no need to do this if you already have a Folder Id)
office365.ListContacts(office365.ContactFolders[0].Id); //Lists contacts
```

**Example (List all Contacts in the default Contacts folder):**

```csharp
office365.ListContacts("");
```

If the number of contacts exceeds the page size, the [list_contacts_marker](#list_contacts_marker-property-office365-struct) will be populated. You can call **ListContacts** again to retrieve the next page of contacts. These contacts will be added to the end of the contacts collection.

**Example (List all Contacts Pages in the default Contacts folder):**

```csharp
do{
  office365.ListContacts("");
} while(!office365.ListContactsMarker.isEmpty());
```

### Creating and Updating Contacts

To create a new contact use the [create_contact](#create_contact-method-office365-struct) method and specify the first name, last name, email address and the id of the folder, where the contact will be created. The newly created contact is added at the end of the contacts collection.

**Example (Create a Contact in the default folder (Contacts))**

```csharp
office365.CreateContact("Pavel", "Bansky", "pavelb@contoso.com", "");
```

**Example (Create a Contact in a Folder)**

```csharp
office365.ListContactFolders(""); //This method populates the ContactFolder collection with the contact folders under the root folder.
office365.CreateContact("Pavel", "Bansky", "pavelb@contoso.com", office365.ContactFolders[0].Id);
// Created the contact in the first folder in the ContactFolders collection.
```

 After creating a contact with basic information, select the contact to be edited in the contacts collection, edit its fields and make a call to the [update_contact](#update_contact-method-office365-struct) method. To edit the newly created contact select the last contact of the collection.

**Example (Update a contact)**

```csharp
office365.CreateContact("Pavel", "Bansky", "pavelb@contoso.com", "");// Create a contact in the main contacts folder.

// Set a company name
office365.Contacts[0].CompanyName = "Volkswagen";

// Set notes
office365.Contacts[0].Notes = "testNotes";

// Set multiple phone numbers
office365.Contacts[0].PhonesCount = 2;
office365.Contacts[0].PhoneIndex = 0;
office365.Contacts[0].PhoneType = TOLPhoneTypes.ptMobile;
office365.Contacts[0].PhoneNumber = "0123456789";
office365.Contacts[0].PhoneIndex = 1;
office365.Contacts[0].PhoneType = TOLPhoneTypes.ptBusiness;
office365.Contacts[0].PhoneNumber = "9876543210";

// Update the contact
office365.UpdateContact(0);
```

 The OLContact type used in the contacts collection includes the most commonly used fields for contacts. Refer to the OLContact type for a complete list of fields. If you need to add other fields, you can use the [set_contact_field](#set_contact_field-method-office365-struct) method. For a complete list of fields a contact can have please refer to the Microsoft Graph API documentation.

**Example (Add Other Fields To A Contact)**

```csharp
// Set birthday
office365.SetContactField(0, "/json/birthday", "2024-05-21", 2); // The last argument is the type of the field. 2 (String)

// Set business address
office365.SetContactField(0,
              "/json/businessAddress",
              "{\"street\":\"string\",\"city\":\"string\",\"state\":\"string\",\"countryOrRegion\":\"string\",\"postalCode\":\"string\"}",
              0); // 0 (Object)

// Update the contact
office365.UpdateContact(0);
```

### Retrieving Contacts

 To retrieve a contact use the [get_contact](#get_contact-method-office365-struct) method and provide the Id of the contact as the argument. The contact is added to the end of the contacts collection.

**Example (Retrieve a Contact)**

```csharp
// Retrieve a contact by its ID
string contactId = "12345"; // Replace with the actual contact ID
office365.GetContact(contactId);

// Access the retrieved contact
var retrievedContact = office365.Contacts[office365.Contacts.Count - 1];
retrievedContact.FirstName;  //first name
retrievedContact.LastName;   //last name
retrievedContact.EmailAddressIndex=0;  //set the index to zero to retrieve access the first email address
retrievedContact.EmailAddress;         //first email address value
retrievedContact.PhonesIndex=0;        //set the index to zero to retrieve access the first phone number
retrievedContact.PhoneNumber;          //first phone number value
office365.GetContactField(office365.Contacts.Count - 1, "/json/birthday");   //birthday of the contact
office365.GetContactField(office365.Contacts.Count - 1, "/json/middleName"); //middle name of the contact
```

### Deleting Contacts

To delete a contact use the [delete_contact](#delete_contact-method-office365-struct) method and provide the Id of the contact as the argument. The contact is also removed from the contacts collection.

**Example (Delete a Contact)**

```csharp
// List contacts and search for a contact with the name "John Doe"
office365.ListContacts("folder_id");
for (int i = 0; i < office365.Contacts.Count; i++) {
  if (office365.Contacts[i].DisplayName == "John Doe") {
    //Delete the contact
    office365.DeleteContact(office365.Contacts[i].Id);
    break;
  }
}
```

### Object Lifetime

 The *new()* method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by CloudMail. Due to this, the Office365 struct cannot be disposed of automatically. Please, call the *dispose(&mut; self)* method of Office365 when you have finished using the instance.

## 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 struct 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 struct will select a provider depending on the current platform.

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

## Data Type

Vec

# timeout property ([Office365](#struct-cloudmailoffice365) Struct)

The timeout for the struct.

## Syntax

*Rust Syntax*

```text
fn timeout(&self ) -> Result<i32, CloudMailError> fn set_timeout(&self, value : i32) ->  Option<CloudMailError>
```

## 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 struct will wait for the operation to complete before returning control.

The struct will use do_events 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 struct fails with an error.

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.

## Data Type

i32

# user_id property ([Office365](#struct-cloudmailoffice365) Struct)

The Id or userPrincipalName of the mailbox to access.

## Syntax

*Rust Syntax*

```text
fn user_id(&self ) -> Result<String, CloudMailError> fn set_user_id(&self, value : &str) ->  Option<CloudMailError>
fn set_user_id_ref(&self, value : &String) ->  Option<CloudMailError>
```

## Default Value

""

## Remarks

This property is used to dictate the mailbox that struct requests will target. By default, the struct operates against the mailbox of the user associated with the currently authorized account (i.e., the *me* context).

This property should be set to either the unique Id (an Azure Active Directory object Id) or its userPrincipalName (typically the user's email address), which is required in two common scenarios.

First, when attempting to access a shared mailbox with a delegated authorization flow, this property should be set to the shared mailbox's address with the *mail.read.shared* authorization scope (or *mail.readwrite.shared* to also send and modify messages) included during the OAuth process so the signed-in user can access it.

Second, when authenticating with application permissions instead of delegated permissions, there is no signed-in user to imply a mailbox via the *me* context, so this property must be set to identify which user's mailbox to access.

If this property is not set, the struct will continue to use the *me* context, which is only valid for delegated authorization flows.

## Data Type

String

# add_attachment method ([Office365](#struct-cloudmailoffice365) Struct)

Adds a file attachment to an existing message.

## Syntax

*Rust Syntax*

```text
fn add_attachment(&self, message_id : &str, name : &str, local_file : &str) -> Result<(), CloudMailError>
```

## Remarks

This method adds a file attachment to an existing message, specified by the *MessageId* parameter. To add a more complex attachment, set the *Name* and *LocalFile* parameters and the struct will use the first attachment in the message_attachments properties. As a note, this will **not** clear the message_attachments properties. If the file is larger than the value set in the [AttachmentSimpleUploadLimit](#AttachmentSimpleUploadLimit) configuration, then the struct will use an upload session to upload the attachment in fragments. The size of the fragments are specified in the [AttachmentFragmentSize](#AttachmentFragmentSize) configuration.

This method is **not** used to add attachments to messages that are sent with the [send_mail](#send_mail-method-office365-struct) method.

# add_item_attachment method ([Office365](#struct-cloudmailoffice365) Struct)

Adds an item attachment to an existing message.

## Syntax

*Rust Syntax*

```text
fn add_item_attachment(&self, message_id : &str, msg_to_attach_id : &str, item_json : &str) -> Result<(), CloudMailError>
```

## Remarks

Adds an item attachment to an existing message, specified by the *MessageId* parameter. Item attachments are non-file attachments, such as Outlook messages, events, and contacts. To add another message as an attachment, set the *msgToAttachId* parameter to its ID. To add an event or contact as an attachment, leave the *msgToAttachId* parameter empty and provide the full JSON.

This method is **not** used to add attachments to messages that are sent with the [send_mail](#send_mail-method-office365-struct) method.

**Example (Adding an Existing Message to a New Draft)**

```text
office365.MessageSubject = "Subject";
office365.MessageBodyContentType = "text";
office365.MessageBodyContent = "Body";
office365.MessageTo = "email@example.com";
office365.CreateDraft(0, "");
String messageId = office365.MessageInfo[0].Id;

office365.AddItemAttachment(messageId, "AAMkADNkNJp5JVnQIe9r0=", "");
```

 **Example (Adding an Event to a New Draft)**

```text
office365.MessageSubject = "Subject";
office365.MessageBodyContentType = "text";
office365.MessageBodyContent = "Body";
office365.MessageTo = "email@example.com";
office365.CreateDraft(0, "");
String messageId = office365.MessageInfo[0].Id;

office365.AddItemAttachment(messageId, "", "{\"@odata.type\": \"#microsoft.graph.itemAttachment\", \"name\": \"Holiday event\", \"item\":{ \"@odata.type\": \"microsoft.graph.event\", \"subject\": \"Discuss gifts for children\", \"body\":{ \"content\": \"Let's look for funding!\"}, \"start\": {\"dateTime\": \"2016-12-02T18:00:00\"}, \"end\": {\"dateTime\": \"2016-12-02T19:00:00\"}}}");
```

# authorize method ([Office365](#struct-cloudmailoffice365) Struct)

Get the authorization string required to access the protected resource.

## Syntax

*Rust Syntax*

```text
fn authorize(&self) -> Result<(), CloudMailError>
```

## 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 [o_auth_client_profile](#o_auth_client_profile-property-office365-struct) property and the [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) property. This method is **not** to be used in conjunction with the [authorization](#authorization-property-office365-struct) property. It should instead be used when setting the o_auth property.

For more information, see the introduction section.

# config method ([Office365](#struct-cloudmailoffice365) Struct)

Sets or retrieves a configuration setting.

## Syntax

*Rust Syntax*

```text
fn config(&self, configuration_string : &str) ->  Result<String, CloudMailError>
```

## Remarks

config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-office365-struct) for the struct.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, 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-office365-struct), you must call *Config("PROPERTY")*. The value will be returned as a string.

# copy method ([Office365](#struct-cloudmailoffice365) Struct)

Creates a copy of a message.

## Syntax

*Rust Syntax*

```text
fn copy(&self, id : &str, destination_id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method copies a message to a folder. *id* takes the ID of the message to be copied, and *destinationId* takes the ID of the folder the message will be copied to.

# copy_folder method ([Office365](#struct-cloudmailoffice365) Struct)

Copies a folder.

## Syntax

*Rust Syntax*

```text
fn copy_folder(&self, id : &str, dest_folder_id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method copies a folder to a new parent folder. Please note that two folders with the same name may not exist under the same parent folder. Since this method does not change the name of a folder, it is not possible to directly create a copy of a folder in the original folder's location.

# create_category method ([Office365](#struct-cloudmailoffice365) Struct)

Creates a new category.

## Syntax

*Rust Syntax*

```text
fn create_category(&self, display_name : &str, color : &str) -> Result<(), CloudMailError>
```

## Remarks

This method creates a new Office365 category. The created category is added to the end of the categories properties.

**Example**

```text
office365.CreateCategory(categoryName, "preset9");
```

# create_contact method ([Office365](#struct-cloudmailoffice365) Struct)

Creates a contact.

## Syntax

*Rust Syntax*

```text
fn create_contact(&self, first_name : &str, last_name : &str, email_address : &str, parent_id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method creates a new contact with the specified first name, last name, and email address. At least one of the arguments must be provided. If all parameters are null or empty, an error is thrown. The contact is added to the parent folder specified by ParentId. Set ParentId to empty string or null to create the contact in the default Contacts folder of the signed-in user. The new contact is added to the beginning of the contacts list.

After creating a contact with basic information, you can update it and set additional fields by editing the contact in the contacts collection and calling the [update_contact](#update_contact-method-office365-struct) method. For more details, refer to the [update_contact](#update_contact-method-office365-struct) method.

**Example (Create a Contact in the Default Contacts Folder of the User)**

```csharp
office365.CreateContact("Pavel", "Bansky", "pavelb@contoso.com", ""); // Create the contact in the main contacts folder.
```

**Example (Create a Contact in a Folder)**

```csharp
office365.ListContactFolders(""); //This method lists all contact folders in the root folder and populates the ContactFolder collection.
office365.CreateContact("Pavel", "Bansky", "pavelb@contoso.com", office365.ContactFolders[0].Id);
// Created the contact in the first folder in the ContactFolders collection.
```

Note that additional operations on a newly created contact may not be successful if performed immediately after creation. It is recommended to wait two or more second after creation before attempting further operations on the contact resource.

# create_draft method ([Office365](#struct-cloudmailoffice365) Struct)

Creates a new email draft.

## Syntax

*Rust Syntax*

```text
fn create_draft(&self, draft_type : i32, id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method creates a new draft in the Drafts folder. The created message's information, including the draft's message id, is also added to the message_info properties. As a note, this will not clear the properties but will add it to the end.

Valid values for *DraftType* :

|  |  |
| --- | --- |
| 0 | DRAFTTYPE_MESSAGE |
| 1 | DRAFTTYPE_REPLY |
| 2 | DRAFTTYPE_REPLYALL |
| 3 | DRAFTTYPE_FORWARD |

**Important Notes**

When using *DRAFTTYPE_MESSAGE*, pass in an empty string as the *id*. The created draft will be built using the Message* properties (i.e. MessageTo, MessageSubject, MessageFrom, etc.).

When using *DRAFTTYPE_REPLY*, *DRAFTTYPE_REPLYALL*, or *DRAFTTYPE_FORWARD* the *id* parameter can be used to specify the message that is being replied to or forwarded. Also, the created draft will **NOT** be built with the Message* properties. Instead, the created draft will be empty (except for the From field). The [update](#update-method-office365-struct) method can be used instead to fill in the different parts of the message.

**Example (New Draft)**

```text
// Create a draft message
office365.MessageSubject = "Subject Text";
office365.MessageImportance = "High";
office365.MessageBodyContentType = "TEXT";
office365.MessageBodyContent = "Body Text";
office365.MessageTo = "email@example.com";

office365.CreateDraft(0, "");
office365.SendDraft(office365.MessageInfo[0].Id);
```

 **Example (Reply)**

```text
// Create the reply draft
string originalMessageId = "Message ID";
office365.CreateDraft(1, originalMessageId);

// Set the new draft MessageInfo fields with desired options
office365.MessageInfo[0].To = "email@example.com";
office365.MessageInfo[0].Subject = "Subject Text";
office365.MessageInfo[0].BodyContentType = "TEXT";
office365.MessageInfo[0].BodyContent = "Body Text";

// Update the draft
office365.Update(office365.MessageInfo[0].Id);

// Send the draft
office365.SendDraft(office365.MessageInfo[0].Id);
```

# create_folder method ([Office365](#struct-cloudmailoffice365) Struct)

```

## Remarks

This method lists changed messages within the folder specified by *id*.

### Starting from a Baseline State

For most use-cases, it is necessary to obtain a baseline state first in order to only list messages that have been changed after the baseline state was established.

To obtain a baseline state, ensure that both [change_marker](#change_marker-property-office365-struct) and [next_change_marker](#next_change_marker-property-office365-struct) are empty, and then call list_changes. Then follow the process described in the "General Usage" section (below) until [change_marker](#change_marker-property-office365-struct) is empty to list all the changed messages.

### General Usage

When this method is called, it will use the change marker stored in either [change_marker](#change_marker-property-office365-struct) or [next_change_marker](#next_change_marker-property-office365-struct) (only one can be populated at a time) to request the next page of changes. This method causes the [on_message_list](#on_message_list-event-office365-struct) event to fire once for each change, and will also populate the message_info properties.

If there are still more messages available to list when this method returns, the [change_marker](#change_marker-property-office365-struct) property will be populated. Continue to call this method until [change_marker](#change_marker-property-office365-struct) is empty to accumulate all pages of results in the message_info properties (Once there aren't any more changed messages available to list, the [next_change_marker](#next_change_marker-property-office365-struct) property will be populated instead).

When [next_change_marker](#next_change_marker-property-office365-struct) 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 list_changes immediately after [next_change_marker](#next_change_marker-property-office365-struct) is populated will not return any further changes.)

# list_contact_folders method ([Office365](#struct-cloudmailoffice365) Struct)

Lists the contact folders found in the parent folder.

## Syntax

*Rust Syntax*

```text
fn list_contact_folders(&self, parent_folder_id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method retrieves and lists the contact folders within the specified parent folder. It clears and then populates the contact_folders collection with the retrieved folders.

To list all contact folders in the root folder, set the *parentFolderId* parameter to an empty string.

**Example (List All Contact Folders in the Root Folder): **

```csharp
office365.ListContactFolders(""); // List root folders.
foreach(OLContactFolder folder in office365.ContactFolders){
  folder.Id;              // Folder id
  folder.Name;            // Folder name
  folder.ParentFolderId;  // Folder parent id
}
```

 **Example (List all Contact Sub Folders in a Folder):**

```csharp
office365.ListContactFolders("");
office365.ListContactFolders(office365.ContactFolders[0].Id); //List the sub folders of the first root folder.
office365.ContactFolders[0]; // The first sub folder of the first root folder.
```

If the number of contact folders exceeds the page size, the [ListContactFoldersMarker](#ListContactFoldersMarker) config value will be populated. You can call **ListContactFolders** again to retrieve the next page of folders. These folders will be added to the end of the contact_folders collection.

**Example (List All Contact Folders Pages in the Root Folder):**

```csharp
do{
  office365.ListContactFolders(""); // List root folders.
} while (!office365.Config("ListContactFoldersMarker").IsEmpty());
```

# list_contacts method ([Office365](#struct-cloudmailoffice365) Struct)

Lists the contacts in a folder.

## Syntax

*Rust Syntax*

```text
fn list_contacts(&self, folder_id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method retrieves and lists the contacts within the specified folder. It clears and then populates the contacts collection with the retrieved contacts. Providing an empty string as *folderId* retrieves the contacts from the default Contacts folder of the signed-in user.

**Example (List All Contacts in a Folder)**

```text
office365.ListContactFolders(""); // List root folders (no need to do this if you already have a Folder Id)
office365.ListContacts(office365.ContactFolders[0].Id); //Lists contacts
```

**Example (List all Contacts in the default Contacts folder):**

```csharp
office365.ListContacts("");
```

If the number of contacts exceeds the page size, the [list_contacts_marker](#list_contacts_marker-property-office365-struct) will be populated. You can call **ListContacts** again to retrieve the next page of contacts. These contacts will be added to the end of the contacts collection.

**Example (List all Contacts Pages in the default Contacts folder):**

```csharp
do{
  office365.ListContacts("");
} while(!office365.ListContactsMarker.isEmpty());
```

# list_folders method ([Office365](#struct-cloudmailoffice365) Struct)

```text
fn list_folders(&self, parent_folder_id : &str) -> Result<(), CloudMailError>
```

## Remarks

This method lists the folders found in the parent folder. This method clears populates the folders properties.

Set *parentFolderId* to be an empty string to list all folders in the root folder.

If the number of folders is greater than the folder page size, [list_folders_marker](#list_folders_marker-property-office365-struct) will be populated and calling list_folders again will list the next page of folders.

**Example (List All Folders in the Root Folder)**

```text
office365.ListFolders("");
```

# list_messages method ([Office365](#struct-cloudmailoffice365) Struct)

Lists the messages in a folder.

## Syntax

*Rust Syntax*

```text
fn list_messages(&self, folder_id : &str, filter : &str) -> Result<(), CloudMailError>
```

## Remarks

This method lists the messages found in the specified folder. This method clears and populates the message_info properties.

If the number of messages is greater than the message page size, [list_messages_marker](#list_messages_marker-property-office365-struct) will be populated and calling list_messages again will list the next page of messages.

*filter* can be used to retrieve a specific subset of messages, or it can be left as an empty string to retrieve all messages in a folder. *filter* follows the OData protocol syntax.

**Example (List All Messages in a Folder)**

```text
office365.ListMessages(folderId, "");
```

**Example (List Unread Messages in a Folder)**

```text
office365.ListMessages(folderId, "isRead eq false");
```

To update a contact, edit the desired contact fields within the contacts collection. Then, call the update_contact method with the index of the contact. Note that changing the JSON data will overwrite the entire contact, ignoring other field edits made before setting the JSON.

The OLContact type used in the contacts collection includes the most commonly used fields for contacts. Refer to the OLContact type for a complete list of fields. If you need to add other fields, you can use the [set_contact_field](#set_contact_field-method-office365-struct) method. For a complete list of fields a contact can have please refer to the Microsoft Graph API documentation.

Example:

```csharp
office365.CreateContact("Pavel", "Bansky", "pavelb@contoso.com", "");// Create a contact in the main contacts folder.

// Set a company name
office365.Contacts[0].CompanyName = "Volkswagen";

Fired after the server presents its certificate to the client.

## Syntax

*Rust Syntax*

```text
// Office365SSLServerAuthenticationEventArgs carries the Office365 SSLServerAuthentication event's parameters.
pub struct Office365SSLServerAuthenticationEventArgs {
  fn cert_encoded(&self) -> &[u8]
  fn cert_subject(&self) -> &String
  fn cert_issuer(&self) -> &String
  fn status(&self) -> &String
  fn accept(&self) -> bool
  fn set_accept(&self, value : bool)
}

// Office365SSLServerAuthenticationEvent defines the signature of the Office365 SSLServerAuthentication event's handler function.
pub trait Office365SSLServerAuthenticationEvent {
  fn on_ssl_server_authentication(&self, sender : Office365, e : &mut Office365SSLServerAuthenticationEventArgs);
}

impl <'a> Office365<'a> {
  pub fn on_ssl_server_authentication(&self) -> &'a dyn Office365SSLServerAuthenticationEvent;
  pub fn set_on_ssl_server_authentication(&mut self, value : &'a dyn Office365SSLServerAuthenticationEvent);
  ...
}
```

## 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.

# on_ssl_status event ([Office365](#struct-cloudmailoffice365) Struct)

Fired when secure connection progress messages are available.

## Syntax

*Rust Syntax*

```text
// Office365SSLStatusEventArgs carries the Office365 SSLStatus event's parameters.
pub struct Office365SSLStatusEventArgs {
  fn message(&self) -> &String
}

// Office365SSLStatusEvent defines the signature of the Office365 SSLStatus event's handler function.
pub trait Office365SSLStatusEvent {
  fn on_ssl_status(&self, sender : Office365, e : &mut Office365SSLStatusEventArgs);
}

impl <'a> Office365<'a> {
  pub fn on_ssl_status(&self) -> &'a dyn Office365SSLStatusEvent;
  pub fn set_on_ssl_status(&mut self, value : &'a dyn Office365SSLStatusEvent);
  ...
}
```

## Remarks

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

# on_transfer event ([Office365](#struct-cloudmailoffice365) Struct)

Fired while a document transfers (delivers document).

## Syntax

*Rust Syntax*

```text
// Office365TransferEventArgs carries the Office365 Transfer event's parameters.
pub struct Office365TransferEventArgs {
  fn direction(&self) -> i32
  fn bytes_transferred(&self) -> i64
  fn percent_done(&self) -> i32
  fn text(&self) -> &[u8]
}

// Office365TransferEvent defines the signature of the Office365 Transfer event's handler function.
pub trait Office365TransferEvent {
  fn on_transfer(&self, sender : Office365, e : &mut Office365TransferEventArgs);
}

impl <'a> Office365<'a> {
  pub fn on_transfer(&self) -> &'a dyn Office365TransferEvent;
  pub fn set_on_transfer(&mut self, value : &'a dyn Office365TransferEvent);
  ...
}
```

## 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 *bytes_transferred* 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.

# Config Settings ([Office365](#struct-cloudmailoffice365) Struct)

 The struct 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 struct, access to these *internal properties* is provided through the [config](#config-method-office365-struct) method.

### Office365 Config Settings

**AttachmentFragmentSize**: Size of fragments when uploading large attachments.This setting specifies the size, in bytes, of the fragments that are uploaded during an advanced upload session when using the [add_attachment](#add_attachment-method-office365-struct) method.

The default value is *2097152* (2MiBs).

**AttachmentJSON[i]**: The raw JSON for the selected attachment.This method returns the raw JSON for the selected attachment. The attachment index correlates to the attachments properties.

**AttachmentSimpleUploadLimit**: The threshold to use simple uploads.This setting specifies the limit before the component will switch from simple uploads to upload sessions when using the [add_attachment](#add_attachment-method-office365-struct) method.

The default value is *2097152* (2MiBs).

**ContactFoldersPageSize**: Page size for fetching contact folders.This setting specifies the contact folders page size, or the maximum number of contact folders that will be fetched from the server in one get call.

The default value is *100*.

**ContactsPageSize**: Page size for fetching contacts.This setting specifies the contacts page size, or the maximum number of contacts that will be fetched from the server in one get call.

The default value is *100*.

**FolderPageSize**: Page size for fetching folders.This setting specifies the folder page size, or the maximum number of folders that will be fetched from the server in one get call.

The default value is *100*.

**IncludeNestedItemAttachments**: Whether nested attachments present on item attachment are included in the request.This setting specifies whether item attachments retain their own attachments. If set to *True*, additional requests will be made to ensure that nested attachments present in the item attachment remain. If set to *False* (default), this will not occur, reducing the size of the request.

At this time, Microsoft does not support nested attachments in item attachments. Once support is added, this may be set to *True* to include these attachments with the [add_item_attachment](#add_item_attachment-method-office365-struct) request.

**ItemAttachmentCC[i]**: The CC field of item attachment messages.This method returns the *CC* field for item attachments that are messages. The attachment index correlates to the attachments properties. If the indexed attachment is not a message item attachment, the component will throw an exception.

**ItemAttachmentFrom[i]**: The from field of item attachment messages.This method returns the *From* field for item attachments that are messages. The attachment index correlates to the attachments properties. If the indexed attachment is not a message item attachment, the component will throw an exception.

**ItemAttachmentSentDate[i]**: The SentDate field of item attachment messages.This method returns the *SentDate* field for item attachments that are messages. The attachment index correlates to the attachments properties. If the indexed attachment is not a message item attachment, the component will throw an exception.

**ItemAttachmentSubject[i]**: The Subject field of item attachment messages.This method returns the *Subject* field for item attachments that are messages. The attachment index correlates to the attachments properties. If the indexed attachment is not a message item attachment, the component will throw an exception.

**ItemAttachmentTo[i]**: The CC field of item attachment messages.This method returns the *To* field for item attachments that are messages. The attachment index correlates to the attachments properties. If the indexed attachment is not a message item attachment, the component will throw an exception.

**ListContactFoldersMarker**: The page marker for listing contact folders.This property is populated if there are still unlisted changes after [list_contact_folders](#list_contact_folders-method-office365-struct) is called. It contains the nextLink that will be included as an OData parameter if [list_contact_folders](#list_contact_folders-method-office365-struct) is called again on the same parent folder. This will cause the next page of contact folders to be listed.

**Example (List All Contact Folders in the Root Directory)**

```text
do
{
  office365.ListContactFolders("");
} while (office365.Config("ListContactFoldersMarker").Length > 0);
```

**MessagePageSize**: Page size for fetching messages.This setting specifies the message page size, or the maximum number of messages that will be fetched from the server in one get call.

The default value is *100*.

**MIMEMessage**: MIME encoded message to send.When set with a MIME message, the [send_mail](#send_mail-method-office365-struct) method will use the MIME message rather than the Message* properties.

```text
component.Config("MIMEMessage" + MIME_MESSAGE);
component.SendMail();
```

**Prefer**: Specifies a preferred content header type.This setting can be used to specify a preferred content header type to be used when retrieving messages.

**QueryParamCount**: The number of custom OData Query Parameters.This setting specifies the number of custom OData Query parameters that will be added to a request when fetching data.

The default value is *0*.

**Example:**

```text
component.Config("QueryParamCount=1");
component.Config("QueryParamName[0]=Select");
component.Config("QueryParamValue[0]=name");
```

**QueryParamName[i]**: The name of a custom OData Query Parameter.This setting specifies the name of the custom OData Query parameter at index *i*.

**QueryParamValue[i]**: The value of a custom OData Query Parameter.This setting specifies the value of the custom OData Query parameter at index *i*.

**RequestNestedItemAttachments**: Whether nested attachments present on item attachments are included when listing attachments.When set to true, the [list_attachments](#list_attachments-method-office365-struct) and [retrieve_attachment](#retrieve_attachment-method-office365-struct) methods will recursively iterate through each item attachment in the attachments properties. See [attachment_parent_index](#attachment_parent_index-property-office365-struct) for more information on identifying the parent of each nested attachment. This setting is disabled by default.

**UserId**: Sets the Id of a shared mailbox to connect to.Specifies the Id to use when connecting to the server. When the "mail.read.shared" scope is also added, this allows reading from shared mailboxes. 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-office365-struct) 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-office365-struct) property is not set, the struct 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 [o_auth_refresh_token](#o_auth_refresh_token-property-office365-struct) property should be set to a valid refresh token. When using the Client Credential grant type however, the struct 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 struct will wait for a response from the browser when requesting user authentication. The default value is *0*, meaning that the struct 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-office365-struct) 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 struct 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 [o_auth_client_profile](#o_auth_client_profile-property-office365-struct) 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 property when the [o_auth_grant_type](#o_auth_grant_type-property-office365-struct) is set to the password grant type and [authorize](#authorize-method-office365-struct) 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-office365-struct) method and the [o_auth_web_auth_url](#o_auth_web_auth_url-property-office365-struct) field when [OAuthUsePKCE](#OAuthUsePKCE) is set to true. When using the cocpWeb [o_auth_client_profile](#o_auth_client_profile-property-office365-struct), 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-office365-struct) method will reset the OAuth settings including any authorization fields like [o_auth_access_token](#o_auth_access_token-property-office365-struct) and [o_auth_refresh_token](#o_auth_refresh_token-property-office365-struct). This means the [authorize](#authorize-method-office365-struct) method must be called again to get new authorization information. When set to *false*, the [reset](#reset-method-office365-struct) method will **not** reset the o_auth property and the OAuth* configuration settings. This allows for the struct 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-office365-struct)

**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 [o_auth_grant_type](#o_auth_grant_type-property-office365-struct). 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 struct will automatically start and stop the web server when [authorize](#authorize-method-office365-struct) is called. In certain cases, it is required to start the webserver before calling [authorize](#authorize-method-office365-struct). For example, if the [o_auth_return_url](#o_auth_return_url-property-office365-struct) 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) property 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) property 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-office365-struct) 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 [o_auth_client_profile](#o_auth_client_profile-property-office365-struct) is set to cocpApplication. This specifies the interface on which the embedded web server listens, and also the value displayed in the [o_auth_return_url](#o_auth_return_url-property-office365-struct). 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-office365-struct) 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 struct 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 struct 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 struct will accept compressed data. It then will uncompress the data it has received. The struct will handle data compressed by both gzip and deflate compression algorithms.

When True, the struct 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 http_version is set to "2.0".

If set to True (default), the struct will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the struct fails with an error if the server does not support HTTP/2.

The default value is True.

**Append**: Whether to append data to LocalFile.This configuration setting determines whether data will be appended when writing to local_file. When set to True, downloaded data will be appended to local_file. This may be used in conjunction with range to resume a failed download. This is applicable only when local_file 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 struct can be extended with other security schemes in addition to the authorization schemes already implemented by the struct.

The auth_scheme 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-office365-struct) 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 [on_transfer](#on_transfer-event-office365-struct) 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 struct.If set to True, the URL passed to the struct 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 struct 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 struct fails with an error.

**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 on_redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the on_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 struct fails with an error instead.

Following are the valid options:

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

**GetOn302Redirect**: If set to True the struct will perform a GET on the new location.The default value is False. If set to True, the struct 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 struct.This property specifies the HTTP version used by the struct. 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 struct 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/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 [on_log](#on_log-event-office365-struct) 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).

**MaxRedirectAttempts**: Limits the number of redirects that are followed in a request.When follow_redirects is set to any value other than frNever, the struct 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 http_version is set to "2.0" (if the server does not support "2.0"), then the struct 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 struct 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 [proxy_user](#proxy_user-property-office365-struct) and [proxy_password](#proxy_password-property-office365-struct) are specified, this value is calculated using the algorithm specified by [proxy_auth_scheme](#proxy_auth_scheme-property-office365-struct).

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

**ProxyPort**: Port for the proxy server (default 80).This configuration setting is provided for use by structs 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 structs 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 structs 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 struct.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 struct.

**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 struct 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 struct 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. NOTE: The [CodePage](#CodePage) setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set [CodePage](#CodePage) to *65001*. In the C++ Edition for Windows, the *W version of the class must be used. For instance, *DNSW* or *HTTPW*.

**UseProxyAutoConfigURL**: Whether to use a Proxy auto-config file when attempting a connection.This configuration specifies whether the struct will attempt to use the Proxy auto-config URL when establishing a connection and [proxy_auto_detect](#proxy_auto_detect-property-office365-struct) is set to *True*.

When *True* (default), the struct 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

**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 struct will use [timeout](#timeout-property-office365-struct) for establishing a connection and transmitting/receiving data.

**FirewallAutoDetect**: Tells the struct whether or not to automatically detect and use firewall system settings, if available.This configuration setting is provided for use by structs 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 structs 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.

**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 struct fails with an error.

NOTE: This setting is provided for use by structs 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 structs 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 structs 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 struct fails with an error.

NOTE: This setting is provided for use by structs 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 struct 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 local_host 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 struct initiate connections (or accept in the case of server structs) only through that interface.

If the struct is connected, the local_host 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 struct binds. This configuration setting must be set before a connection is attempted. It instructs the struct 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 local_port after the connection is established.

local_port 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 on_data_in 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 on_data_in 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 struct will use IPv4 exclusively. When set to *1*, the struct will use IPv6 exclusively. To instruct the struct 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

**LogSSLPackets**: Controls whether SSL packets are logged when using the internal security API.When [ssl_provider](#ssl_provider-property-office365-struct) 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 [on_ssl_status](#on_ssl_status-event-office365-struct) event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if [ssl_provider](#ssl_provider-property-office365-struct) is set to *Platform*.

**OpenSSLCADir**: The path to a directory containing CA certificates.This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

**OpenSSLCAFile**: Name of the file containing the list of CA's trusted by your application.This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:

 -----BEGIN CERTIFICATE-----

 ... (CA certificate in base64 encoding) ...

 -----END CERTIFICATE-----

 Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

**OpenSSLCipherList**: A string that controls the ciphers to be used by SSL.This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

**OpenSSLPrngSeedData**: The data to seed the pseudo random number generator (PRNG).This functionality is available only when the provider is OpenSSL.

By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

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

If set to True, the struct 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 struct is the same.

**SSLCACerts**: A newline separated list of CA certificates to be included when performing an SSL handshake.When [ssl_provider](#ssl_provider-property-office365-struct) is set to *Internal*, this configuration setting specifies one or more CA certificates to be included with the ssl_cert 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
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----
```

**SSLCheckCRL**: Whether to check the Certificate Revocation List for the server certificate.This configuration setting specifies whether the struct will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the struct will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The struct 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 struct fails with an error.

When set to 0 (default), the CRL check will not be performed by the struct. 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 struct will use OCSP to check the validity of the server certificate. If set to 1 or 2, the struct will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The struct 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 struct fails with an error.

When set to 0 (default), the struct 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 [on_ssl_status](#on_ssl_status-event-office365-struct) 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 ssl_authenticate_clients 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 struct 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 [ssl_provider](#ssl_provider-property-office365-struct) is set to *Platform* include the following:

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

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 struct will first try to use the platform TLS 1.3 implementation when the [ssl_provider](#ssl_provider-property-office365-struct) 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, [ssl_provider](#ssl_provider-property-office365-struct) 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 struct when the [ssl_provider](#ssl_provider-property-office365-struct) is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and [ssl_provider](#ssl_provider-property-office365-struct) 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 [ssl_provider](#ssl_provider-property-office365-struct) 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 [on_ssl_server_authentication](#on_ssl_server_authentication-event-office365-struct) 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 [on_ssl_server_authentication](#on_ssl_server_authentication-event-office365-struct) event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-office365-struct) event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

**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 struct 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 struct will only append, it will not overwrite previous values.

NOTE: This configuration setting is applicable only when [ssl_provider](#ssl_provider-property-office365-struct) 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 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

... 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 [ssl_provider](#ssl_provider-property-office365-struct) is set to *Internal* and [SSLEnabledProtocols](#SSLEnabledProtocols) is set to allow TLS 1.2.

When specified the struct 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 struct fails with an error.

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 [ssl_provider](#ssl_provider-property-office365-struct) 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)

- "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-office365-struct) 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 struct 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 struct 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.

**CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

The following is a list of valid code page identifiers:

**LicenseInfo**: Information about the current license.When queried, this setting will return a string containing information about the license this instance of a struct 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*.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the struct will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to *true* tells the struct 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.

 To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section.
