CloudMailer Component
Properties Methods Events Config Settings Errors
The CloudMailer component is used to send HTML emails with a variety of mail service providers.
Syntax
nsoftware.CloudMail.Cloudmailer
Remarks
The CloudMailer component provides the ability to send simple emails with Amazon's Simple Email Service (SES), Google's Gmail, and Microsoft's Office 365 all from a single place. To use the component, first choose the correct service provider with the ServiceProvider property, set the Account property to valid credentials, and then specify message details with properties such as MessageHTML, Subject, SendTo, and more before sending with the Send method.
Below is a brief description of how to authenticate with each service provider and send a simple message.
Authentication
All included service providers require some manner of authentication to be completed and set in the Account property before they can be used to send messages.
Amazon SES
Authentication with Amazon SES requires setting the AmazonAccessKey and AmazonSecretKey fields to valid Amazon Web Services credentials.
Gmail
Authentication with Gmail requires setting the Authorization field to a valid OAuth token. To perform OAuth authentication, use the OAuth property to set the appropriate fields for the chosen ClientProfile and GrantType.
When Gmail is the active ServiceProvider, the following OAuth values are default:
Authorization Server URL | "https://accounts.google.com/o/oauth2/auth" |
Token Server URL | "https://accounts.google.com/o/oauth2/token" |
Scopes | "https://www.googleapis.com/auth/gmail.readonly https://www.googleapis.com/auth/gmail.modify https://www.googleapis.com/auth/gmail.compose https://mail.google.com/" |
Office 365
Authentication with Office 365 requires setting the Authorization field to a valid OAuth token. To perform OAuth authentication, use the OAuth property to set the appropriate fields for the chosen ClientProfile and GrantType.
When Office365 is the active ServiceProvider, the following OAuth values are default:
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 user.read" |
Additionally, depending on how the application is registered (ex. multi-tenant) and what GrantType is selected (ex. client credentials and password), it may be required to use the tenant ID rather than "common" in the ServerAuthURL and ServerTokenURL fields. In the case of the client credentials and password grant types, it is also required to use the "default" scopes of the app registration. See below for examples of the modified URLs and scopes:
Authorization Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/authorize" |
Token Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/token" |
Scopes | "https://graph.microsoft.com/.default" |
Below is a brief description of the different ClientProfile and GrantType values that are supported by this component. For a more in-depth description of what needs to be set, refer to the service documentation.
Application Profile
This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the component. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.
To start the authentication and authorization process, the Authorize method should be called. If the authorization and authentication was successful, then the AccessToken field will be populated. Additionally, if a refresh token was provided the RefreshToken field will be populated as well. These values of the fields are for informational purposes. The component will also cache these tokens along with when the AccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the component will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new AccessToken. If the Authorize method was not used and user interaction would be required, the component will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the GrantType field. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.
A brief description of the supported values for the GrantType field are below. For more information, see the service documentation.
Authorization Code
When using the Authorization Code grant type, the component will use an authorization code to get an access token. For this GrantType the component expects a ClientId, ClientSecret, ServerAuthURL, and ServerTokenURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the component will parse the authorization code, setting the AuthorizationCode field, from the redirect. Immediately, the component will make a request to the token server to exchange the authorization code for an access token. The token server will return an access token and possibly a refresh token. If the RefreshToken field is set, or a refresh token is cached, then the component will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.
Example:
Cloudmailer cloudmailer = new Cloudmailer();
cloudmailer.OAuth.ClientProfile = OAuthClientProfiles.cocpApplication;
cloudmailer.OAuth.GrantType = OAuthGrantTypes.cogtAuthorizationCode;
cloudmailer.OAuth.ClientId = CLIENT_ID;
cloudmailer.OAuth.ClientSecret = CLIENT_SECRET;
cloudmailer.Authorize();
Client Credentials
When using the Client Credentials grant type, the component will act as a service instead of authorizing and authenticating as a user. This allows for the component to avoid user interaction. This is typically used when running in an application that can not have user access. This grant type requires additional set up to be done in the service providers portal before it can be used. For this GrantType the component expects a ClientId, ClientSecret, and ServerTokenURL to be set. When the Authorize method is called, the component will make a request to the token server for an access token. The token server will return an access token if the application has the authorization to do so. When this access token is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.
Implicit
Note: This grant type is considered insecure and should only be used when necessary.
When using the Implicit grant type, the component will request the authorization server to get an access token. For this GrantType the component expects a ClientId, ClientSecret, and ServerAuthURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the component will parse the access token from the redirect.
A disadvantage of the grant type is that can not use a refresh token to silently get a new access token. Most service providers offer a way to silently get a new access token. See the service documentation for specifics. This means the component will not be able to automatically get a fresh token once it expires.
Password
Note: This grant type is considered insecure and should only be used when necessary.
When using the Resource Owner Password Credentials grant type, the component will authenticate as the resource owner. This allows for the component to avoid user interaction. This grant type often has specific limitations put on it by the service provider. See the service documentation for more details.
For this GrantType the component requires OAuthPasswordGrantUsername, ClientSecret, and ServerTokenURL to be set. The ClientSecret should be set to the password of the account instead of a typical secret. In some cases, the ClientId also needs to be set. When the Authorize method is called, the component will make a request to the token server for an access token using the username and password. The token server will return an access token if the authentication was successful. When this access token is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.
Web Profile
This profile is similar to setting the component to the Application profile and Authorization Code grant type except the component will not launch the browser. It is typically used in situations where there is a back-end that is supporting some front end. This profile expects that ClientId, ClientSecret, ServerAuthURL, ServerTokenURL, and the ReturnURL fields to be set. Before calling the Authorize method, the WebAuthURL field should be queried to get a URL. This URL should be used to redirect the user to the authorization page for the service provider. The redirect_uri parameter of this URL is mapped to the ReturnURL field. The ReturnURL field should be set to some web server that will parse the authorization code out of the query parameter from the redirect. Once the authorization code is parsed, it should be passed back to the server where it is then set to the AuthorizationCode field. Once that is set, the Authorize method can be called to exchange the authorization code for an access token and refresh token if provided. The component will then cache these values like normal and use them to make requests. If the RefreshToken field is set, or a refresh token is cached, then the Authorize 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 the OAuth component or a separate process. Once complete you should have an authorization string which looks like:Bearer ACCESS_TOKEN_VALUE
Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the component to ignore the values set in the OAuth property.
Example:
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 = "user.read mail.readwrite mail.send mailboxsettings.readwrite";
oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode;
cloudmailer.Account.Authorization = oauth.GetAuthorization();
Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.
Sending Messages
The component sends a message that is provided in the MessageHTML and MessageText properties. The MessageHTML property contains the HTML version of the message, while the corresponding plaintext version is provided in the MessageText property.
When MessageHTML is set, the component automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.
The recipients are specified by the SendTo, Cc, and BCc properties, and the message subject by the Subject property.
Once all the appropriate properties have been set, call the Send method and the message will be sent to its intended recipient(s).
Example:
cloudmailer.From = "me@gmail.com";
cloudmailer.SendTo = "recipient@server.com";
cloudmailer.Subject = "My Subject";
cloudmailer.MessageHTML = "This is the message body.";
cloudmailer.Send();

Enum CloudmailerSSLProviders sslpAutomatic sslpPlatform sslpInternal End Enum
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the component will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The component will select a provider depending on the current platform.
When Automatic is selected, on Windows the component will use the platform implementation. On Linux/macOS the component will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.
The .NET Standard library will always use the internal implementation on all platforms.
SSLServerCert Property (CloudMailer Component)

Authorize Method (CloudMailer Component)
Get the authorization string required to access the protected resource.
Syntax
public void Authorize(); Async Version public async Task Authorize(); public async Task Authorize(CancellationToken cancellationToken);
Public Sub Authorize() Async Version Public Sub Authorize() As Task Public Sub Authorize(cancellationToken As CancellationToken) As Task
Remarks
This method is used to get an access token that is required to access the protected resource when the ServiceProvider is set to spGMail or spOffice365. The method will act differently based on what is set in the ClientProfile and GrantType fields. This method is not to be used in conjunction with the Authorization field. It should instead be used when setting the OAuth property.
For more information, see the introduction section.
Config Method (CloudMailer Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
ProcessQueue Method (CloudMailer Component)
Sends the messages which have previously been queued into QueueDir .
Syntax
public void ProcessQueue(string queueDir); Async Version public async Task ProcessQueue(string queueDir); public async Task ProcessQueue(string queueDir, CancellationToken cancellationToken);
Public Sub ProcessQueue(ByVal QueueDir As String) Async Version Public Sub ProcessQueue(ByVal QueueDir As String) As Task Public Sub ProcessQueue(ByVal QueueDir As String, cancellationToken As CancellationToken) As Task
Remarks
This method sends the messages which have previously been queued into QueueDir. The PITrail event shows the interaction with the server as messages as are processed.
This method looks in the directory for files with extension ".queued" and starts processing them.
When processing starts, the file extension is changed to ".sending". If an error happens at this stage, the sending process is aborted, and the file extension is changed to ".failed".
If the file is successfully sent, the file is normally deleted, unless the KeepQueue configuration setting is set to True, in which case the file extension is instead changed to ".sent" and the queue file is not deleted.
Queue Method (CloudMailer Component)
Queues the message into QueueDir .
Syntax
Remarks
This method queues the message into QueueDir. The message is queued into a unique file into the directory QueueDir for future processing.
QueueDir must already exist, or an error will be generated. Alternatively, QueueDir may be set to "*" to return the result as a string instead of writing it to a file.
The method returns the name of the unique queue file created in QueueDir. The file extension is ".queued".
Please refer to the ProcessQueue method for more information on email queue processing.
Reset Method (CloudMailer Component)
Reset the component.
Syntax
public void Reset(); Async Version public async Task Reset(); public async Task Reset(CancellationToken cancellationToken);

component.SendTo = "recipient@server.com"
component.Subject = "My Subject"
component.MessageText = "This is the message body"
component.Send()
SetAttachmentInStream Method (CloudMailer Component)
Sets an attachment using a stream.
Syntax
public void SetAttachmentInStream(int index, System.IO.Stream inputStream); Async Version public async Task SetAttachmentInStream(int index, System.IO.Stream inputStream); public async Task SetAttachmentInStream(int index, System.IO.Stream inputStream, CancellationToken cancellationToken);
Public Sub SetAttachmentInStream(ByVal Index As Integer, ByVal InputStream As System.IO.Stream) Async Version Public Sub SetAttachmentInStream(ByVal Index As Integer, ByVal InputStream As System.IO.Stream) As Task Public Sub SetAttachmentInStream(ByVal Index As Integer, ByVal InputStream As System.IO.Stream, cancellationToken As CancellationToken) As Task
Remarks
This method allows for setting an attachment in the Attachments collection through a stream using the InputStream parameter. The Index parameter specifies which attachment in the Attachments collection the stream will affect.
Note: When multiple attachment sources are provided, the component prioritizes the input stream first, followed by the file path and finally the raw data.
Example
component.Attachments.Add(new FileAttachment("attachment1.txt"));
component.SetAttachmentInStream(0, new FileStream("C:\attachment1.txt", FileMode.Open));
Error Event (CloudMailer Component)

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
Log Event (CloudMailer Component)
This event fires once for each log message.
Syntax
public event OnLogHandler OnLog; public delegate void OnLogHandler(object sender, CloudmailerLogEventArgs e); public class CloudmailerLogEventArgs : EventArgs { public int LogLevel { get; } public string Message { get; } public string LogType { get; } }
Public Event OnLog As OnLogHandler Public Delegate Sub OnLogHandler(sender As Object, e As CloudmailerLogEventArgs) Public Class CloudmailerLogEventArgs Inherits EventArgs Public ReadOnly Property LogLevel As Integer Public ReadOnly Property Message As String Public ReadOnly Property LogType As String End Class
Remarks
This event fires once for each log message generated by the component. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of message. Possible values are as follows:
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are logged. |
The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.
The value 2 (Verbose) logs additional information about the request and response.
The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).
Message is the log entry.

Fired after the server presents its certificate to the client.
Syntax
public event OnSSLServerAuthenticationHandler OnSSLServerAuthentication; public delegate void OnSSLServerAuthenticationHandler(object sender, CloudmailerSSLServerAuthenticationEventArgs e); public class CloudmailerSSLServerAuthenticationEventArgs : EventArgs { public string CertEncoded { get; }
public byte[] CertEncodedB { get; } public string CertSubject { get; } public string CertIssuer { get; } public string Status { get; } public bool Accept { get; set; } }
Public Event OnSSLServerAuthentication As OnSSLServerAuthenticationHandler Public Delegate Sub OnSSLServerAuthenticationHandler(sender As Object, e As CloudmailerSSLServerAuthenticationEventArgs) Public Class CloudmailerSSLServerAuthenticationEventArgs Inherits EventArgs Public ReadOnly Property CertEncoded As String
Public ReadOnly Property CertEncodedB As Byte() Public ReadOnly Property CertSubject As String Public ReadOnly Property CertIssuer As String Public ReadOnly Property Status As String Public Property Accept As Boolean End Class
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (CloudMailer Component)
Shows the progress of the secure connection.
Syntax
public event OnSSLStatusHandler OnSSLStatus; public delegate void OnSSLStatusHandler(object sender, CloudmailerSSLStatusEventArgs e); public class CloudmailerSSLStatusEventArgs : EventArgs { public string Message { get; } }

This field tells the component whether or not to automatically detect and use proxy system settings, if available. The default value is false.
Password
string
Default Value: ""
This field contains a password if authentication is to be used for the proxy.
If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].
If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.
If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.
Constructors
Config Settings (CloudMailer Component)
The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.CloudMailer Config Settings
Bearer (default) | When the access token returned by the server is a Bearer type, the authorization string returned by Authorize will be in the format "Bearer access_token". This can be supplied as the value of the HTTP Authorization header. |
For example, when using the Authorization Code grant type, the RefreshToken field should be set to a valid refresh token. When using the Client Credential grant type however, the component does not need any additional properties set as it can already get a new access token without user interaction.
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.
To parse the payload for specific claims, see OAuthJWTXPath.
The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

XPath Syntax
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. |
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 JWTXText.
The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.
The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.
component.Config("OAuthParamCount=2");
component.Config("OAuthParamName[0]=myvar");
component.Config("OAuthParamValue[0]=myvalue");
component.Config("OAuthParamName[1]=testname");
component.Config("OAuthParamValue[1]=testvalue");
Addtionally, this will also be updated to hold the parameters returned in the response.
for (int i = 0; i < int.Parse(component.Config("OAuthParamCount")); i++)
{
string name = component.Config("OAuthParamName["+i+"]");
string value = component.Config("OAuthParamValue[" + i + "]");
}
- 1 (Plain)
- 2 (S256/SHA256 - default)
This setting can also be set to activate or deactivate the web server. Under normal circumstances, this would not be required as the component will automatically start and stop the web server when Authorize is called. In certain cases, it is required to start the webserver before calling Authorize. For example, if the ReturnURL needs to be set to a relay server, then you will need to start the web server manually. Another example would be when the OAuthReUseWebServer 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.
The OAuthWebServerCertStoreType field specifies the type of the certificate store specified by OAuthWebServerCertStore. If the store is password protected, specify the password in OAuthWebServerCertStorePassword.
OAuthWebServerCertStore is used in conjunction with the OAuthWebServerCertSubject field in order to specify the certificate to be used during SSL.
Designations of certificate stores are platform dependent.
The following designations are the most common User and Machine certificate stores in Windows:
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root certificates. |
When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, 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 is set to true.
Note: This is only applicable when OAuthWebServerSSLEnabled is set to true.
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. |
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=support@nsoftware.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 is set to true.
The default value is localhost.
Regions:
Value | Region |
us-east-1 (Default) | US East (N. Virginia) |
us-east-2 | US East (Ohio) |
us-west-1 | US West (N. California) |
us-west-2 | US West (Oregon) |
ap-east-1 | Asia Pacific (Hong Kong) |
ap-northeast-1 | Asia Pacific (Tokyo) |
ap-northeast-2 | Asia Pacific (Seoul) |
ap-northeast-3 | Asia Pacific (Osaka-Local) |
ap-south-1 | Asia Pacific (Mumbai) |
ap-southeast-1 | Asia Pacific (Singapore) |
ap-southeast-2 | Asia Pacific (Sydney) |
ca-central-1 | Canada (Central) |
cn-north-1 | China (Beijing) |
cn-northwest-1 | China (Ningxia) |
eu-central-1 | Europe (Frankfurt) |
eu-north-1 | Europe (Stockholm) |
eu-south-1 | Europe (Milan) |
eu-west-1 | Europe (Ireland) |
eu-west-2 | Europe (London) |
eu-west-3 | Europe (Paris) |
me-south-1 | Middle East (Bahrain) |
sa-east-1 | South America (Sao Paulo) |
The component will always convert this property's value to lowercase. If this property is cleared, the component will reset it to the default value.
XPath Syntax
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 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. |
XPath Examples
Assuming the following XML response:
<firstlevel> <one>value</one> <two> <item>first</item> <item>second</item> </two> <three>value three</three> </firstlevel>
Or, alternatively, the following JSON response:
{ "firstlevel": { "one": "value", "two": ["first", "second"], "three": "value three" } }
Here are some examples of valid XPaths:
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 is not an exhaustive list by any means, but should provide a general idea of the possibilities.
The current element is specified in the XPath configuration setting. This configuration setting is read-only.
HTTP Config Settings
When True, the component adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".
The default value is True.
If set to True (default), the component will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the component throws an exception if the server does not support HTTP/2.
The default value is True.
This property is provided so that the HTTP component can be extended with other security schemes in addition to the authorization schemes already implemented by the component.
The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".
The default value is False.
If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the component throws an exception.
Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.
A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).
The default value is 0 (Never). In this case, redirects are never followed, and the component throws an exception instead.
Following are the valid options:
- 0 - Never
- 1 - Always
- 2 - Same Scheme
- "1.0"
- "1.1" (default)
- "2.0"
- "3.0"
When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.
HTTP/2 Notes
When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.
If the server does not support HTTP/2, the component will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.
HTTP/2 is supported on all versions of Windows. If the Windows version is an earlier version than Windows 8.1/Windows Server 2012 R2, the internal security implementation will be used. If the Windows version is Window 8.1/Windows Server 2012 R2 or later, the system security libraries will be used by default.
HTTP/3 Notes
HTTP/3 is supported only in .NET and Java.
When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.
The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example:
Sat, 29 Oct 2017 19:43:31 GMT.
The default value for KeepAlive is false.
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).
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .
Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.
This configuration setting is useful for extending the functionality of the component beyond what is provided.
.NET
Http http = new Http();
http.Config("TransferredRequest=on");
http.PostData = "body";
http.Post("http://someserver.com");
Console.WriteLine(http.Config("TransferredRequest"));
C++
HTTP http;
http.Config("TransferredRequest=on");
http.SetPostData("body", 5);
http.Post("http://someserver.com");
printf("%s\r\n", http.Config("TransferredRequest"));
Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.
The default value is False and the hostname will always be used exactly as specified.
When True (default), the component will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.
Override the default with the name and version of your software.
TCPClient Config Settings
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by components that do not directly expose Firewall properties.
If this entry is set, the component acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.
RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.
The connection to the firewall is made by calling the Connect method.
Note: This setting is provided for use by components that do not directly expose Firewall properties.
Note: This configuration setting is provided for use by components that do not directly expose Firewall properties.
0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect through a SOCKS4A Proxy. FirewallPort is set to 1080. |
Note: This setting is provided for use by components that do not directly expose Firewall properties.
Note: This setting is provided for use by components that do not directly expose Firewall properties.
Note: This value is not applicable in macOS.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if 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 is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the component returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.
If the component is connected, the LocalHost 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 multi-homed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

Note: This value is not applicable in Java.
By default, this config is set to false.
0 | IPv4 Only |
1 | IPv6 Only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
The value is formatted as a list of paths separated by semicolons. The component will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.
The default value is:
/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this setting has no effect if SSLProvider is set to Platform.
If set to true, the component will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the component is the same.

When set to 0 (default) the CRL check will not be performed by the component. When set to 1, it will attempt to perform the CRL check, but 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 only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
When set to 0 (default) the component will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but 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 only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this 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 is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default) |
TLS1.1 | 768 (Hex 300) (Default) |
TLS1 | 192 (Hex C0) (Default) |
SSL3 | 48 (Hex 30) [Platform Only] |
SSL2 | 12 (Hex 0C) [Platform Only] |
SSLEnabledProtocols - TLS 1.3 Notes
By default when TLS 1.3 is enabled the component will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions which are designed to run on Windows SSLProvider 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 only supported 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 only available on Windows 11 / Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the component when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This setting is only applicable when SSLProvider is set to Internal.
If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
Note: When SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.
When set, the component will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the component will only append, it will not overwrite previous values.
Note: This setting is only applicable when SSLProvider is set to Internal.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");

This functionality is currently not available in Java or when the provider is OpenSSL.
The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the component will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the component throws an exception.
The format of this value is a comma separated list of hash-signature combinations. For instance:
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 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.
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider 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)
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 setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified 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:

Socket Config Settings
Note: This option is not valid for UDP ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
