REST Connector
The REST component provides a simple, ligthweight and fast way to communicate with RESTful web server.
Remarks
The REST connector implements a highly configurable HTTP client that is capable of sending and receiving data to and from web servers. Support includes issuing simple GET requests as well as defining custom form and file parameters to be POSTed to server. URL defines the location to which the request is made.
The connector supports HTTP 1.0, 1.1, and 2.0 which can be configured in the HTTPVersion property.
The HTTPMethod property defines the HTTP method to use. Possible values are:
- DELETE
- GET (default)
- HEAD
- POST
- PUT
- TRACE
Getting Data From the Server
In the REST Send Connector, if HTTPMethod is set to GET the request is issued to the server specified by URL. Additional custom headers may be specified in the request by setting OtherHeaders.
The response received by the connector will be used as the body of the submitted message. In the case of the Send Connector the response message is only returned when the connector is configured in a solicit response port (recommended). The HTTP headers of the response are available via the TransferredHeaders context property of the message.
Sending Data To the Server
When HTTPMethod is set to POST or PUT data will be sent to the server. The RequestParams property specifies one or more parameters to add to the POST or PUT request. This property is only applicable when the HTTPMethod property is set to POST or PUT.
To specify additional parameters set this property to one or more name value pairs. Set one pair on each line. For instance:
name1=value1
name2=value2
The connector will format a request with parameters slightly differently depending on whether the request is made by the Send or Receive adapter.
Note: To have complete control over the data being sent set PostData instead.
Send Connector
When sending a POST or PUT request the message payload will always be used as the last parameter regardless of the values specified in RequestParams. If no values are set here then a request will be made with only one parameter which is the content of the message. Several examples and additional details follow.
Basic Example:
Setting the RequestParams to a value of:
name1=value1
name2=value2
Will result in a HTTP request like this:
POST / HTTP/1.1
Host: www.nsoftware.com
Accept-Encoding: gzip, deflate
User-Agent: IPWorks HTTP Component - www.nsoftware.com
Connection: close
Content-Type: multipart/form-data; boundary="boundaryV+iTxA=="
Content-Length: 335
--boundaryV+iTxA==
Content-Disposition: form-data; name="name1"
Content-Type: text/plain
value1
--boundaryV+iTxA==
Content-Disposition: form-data; name="name2"
Content-Type: text/plain
value2
--boundaryV+iTxA==
Content-Disposition: form-data
Content-Type: application/octet-stream
message body
--boundaryV+iTxA==--
Notice that the default "Content-Type" for the individual request parameters is "text/plain", and the default "Content-Type" for the message form variable is "application/octet-stream" and has no defined name attribute. See the following examples for further details.
Custom Request Parameter Content-Type Values:
When sending requests the RequestParams may optionally include a custom Content-Type value. The syntax is:
[ContentType]name=value
For instance setting RequestParams to a value of:
[text/html]name1=value1
[my/type]name2=value2
name3=value3
Will result in a HTTP request like:
POST / HTTP/1.1
Host: www.nsoftware.com
Accept-Encoding: gzip, deflate
User-Agent: IPWorks HTTP Component - www.nsoftware.com
Connection: close
Content-Type: multipart/form-data; boundary="boundaryQDNEUw=="
Content-Length: 439
--boundaryQDNEUw==
Content-Disposition: form-data; name="name1"
Content-Type: text/html
value1
--boundaryQDNEUw==
Content-Disposition: form-data; name="name2"
Content-Type: my/type
value2
--boundaryQDNEUw==
Content-Disposition: form-data; name="name3"
Content-Type: text/plain
value3
--boundaryQDNEUw==
Content-Disposition: form-data
Content-Type: application/octet-stream
message body
--boundaryQDNEUw==--
Note the updated Content-Type header values for the "name1" and "name2" parameters.
Custom Content-Type and Name Values for the Message Payload Variable:
The default Content-Type value for the Message Payload form variable is "application/octet-stream" and no "name" attribute is defined in the Content-Disposition header. These can be explicitly defined in the ContentType and ContentFilename properties. These properties are applicable to the Message Payload form variable even if RequestParams is not set. For instance setting:
- ContentType to "text/html"
- ContentFilename to "myfile.txt"
And leaving RequestParams unspecified (no parameters) will result in a HTTP request like:
POST / HTTP/1.1
Host: www.nsoftware.com
Accept-Encoding: gzip, deflate
User-Agent: IPWorks HTTP Component - www.nsoftware.com
Connection: close
Content-Type: multipart/form-data; boundary="boundaryVAJHkA=="
Content-Length: 142
--boundaryVAJHkA==
Content-Disposition: form-data; name="myfile.txt"
Content-Type: text/html
message body
--boundaryVAJHkA==--
Parsing the Response
The ResponseXPath property may be set to traverse elements within the JSON document. This property implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML document. When this property is set, the connector will parse the response and return the value at the specified location.
For example, let's say the response data from the original request is below.
{
"bag": {
"name": "fanny-pack",
"items": ["camera", "wallet"],
"description": "A hip new design by nsoftware"
}
}
The ResponseXPath property supports both XPath notation and JSONPath notation. For simplicitly, only the XPath notation is shown below. For more information and examples on notation schemes please see "Getting Started with JSON".
If you would like to return the value of element "name" from the operation, then set ResponseXPath to /json/bag/name/. Likewise, if you would like to return the value of the first element of the "items" array, then we can set ResponseXPath to /json/bag/items/[0]/ and the output will be camera.
Additional Settings
In addition to the basic operation as discussed above the connector supports a variety of other settings that control authentication, proxy settings, and other behavior. Some of additional features include:
- Authentication (NTLM, Kerberos, Digest, Basic) via the AuthScheme, User, and Password properties.
- Full Proxy/Firewall support using the HTTPProxy and Firewall properties.
- CustomRequestMethod provides support for custom HTTP methods.
- Specify redirect behavior with FollowRedirects.
- Add cookies to the request via Cookies.
- Configurable UserAgent.
- And many more!

AttachedFile Property (REST Connector)
A file to include in the POST data.
Data Type
String
Default Value
""
Remarks
This property optionally specifies a file that will be sent as request parameter. This is only applicable when HTTPMethod is set to POST or PUT.
When set ContentType may be set to specify the Content-Type header for this parameter.
This property is not available in the Receiver.
Authorization Property (REST Connector)
The Authorization string to be sent to the server.
Data Type
String
Default Value
""
Remarks
If the Authorization property contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.
A common use for this property is to specify OAuth authorization string.
This property is provided so that the HTTP connector can be extended with other security schemes in addition to the authorization schemes already implemented by the connector.
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]".
AuthScheme Property (REST Connector)
The authorization scheme to be used when server authorization is to be performed.
Data Type
Enumeration
Possible Values
Basic (0)
Digest (1)
Proprietary (2)
None (3)
Ntlm (4)
Negotiate (5)
OAuth (6)
Default Value
0
Remarks
This property specifies the type of authentication to perform. Possible values are:
- Basic
- Digest
- Proprietary
- None
- NTLM
- Negotiate
- OAuth
In most cases this setting is only applicable if User and Password is set.
This property is also applicable without setting User and Password if the AuthScheme is set to NTLM or Negotiate. In that case the current user credentials will be used.
AuthScheme should be set to authNone (3) when no authentication is to be performed (or do not set HTTPUser and HTTPPassword).
By default, AuthScheme is authBasic (0), and if the HTTPUser and HTTPPassword properties are set, the connector will attempt basic authentication. If AuthScheme is set to authDigest (1) or authNtlm (4), digest or NTLM authentication will be attempted instead.
If AuthScheme is set to authProprietary (2) then the authorization token must be supplied through the HTTPAuthorization configuration. Note that, if you set the HTTPAuthorization config, the AuthScheme will be set automatically to authProprietary (2) by the control.
If AuthScheme is set to authOAuth (6) then the authorization string must be supplied through Authorization property.
ContentFilename Property (REST Connector)
Defines the filename of the content.
Data Type
String
Default Value
""
Remarks
This property optionally sets the "name" attribute of the "Content-Disposition" header for the form variable corresponding to the message payload. This is used to associate a filename with the data obtained from the message payload.
This is only applicable when HTTPMethod is set to POST or PUT.
This is only applicable to the Send Connector.
This is not applicable if PostData is set.
This property is not available in the Receiver.
ContentType Property (REST Connector)
Defines the Content-Type header in the request.
Data Type
String
Default Value
""
Remarks
This property optionally defines the Content-Type header sent in the request.
This is applicable to both the Send and Receive Connector when PostData is set and defines the Content-Type header (not a form variable level Content-Type).
Cookies Property (REST Connector)
The cookies to be sent in the HTTP request.
Data Type
String
Default Value
""
Remarks
This property specifies the cookies (if any) to be sent in the HTTP request. Specify one name/value pair per line. For instance
setting this property to:
CookieName1=CookieValue1
CookieName2=CookieValue2
Will result in the HTTP header:
Cookie: CookieName1=CookieValue1; CookieName2=CookieValue2
Firewall Property (REST Connector)
A set of properties related to firewall access.
Data Type
FirewallRemarks
This is a Firewall type property which contains fields describing the firewall through which the connector will attempt to connect.
FollowRedirects Property (REST Connector)
Determines what happens when the server issues a redirect.
Data Type
Enumeration
Possible Values
Never (0)
Always (1)
Same Scheme (2)
Default Value
0
Remarks
Normally, the connector returns an error if the server responds with an "Object Moved" message. If FollowRedirects is set to frAlways (1) the new URL for the object is retrieved automatically every time.
If FollowRedirects is set to frSameScheme (2), the new URL is retrieved automatically only if the URL scheme is the same, otherwise the connector generate a runtime error.
Furthermore, if either the new URL server and port are different than the existing one, HTTPUser and HTTPPassword are also reset to empty, unless FollowRedirects is set to frAlways (1), in which case the same credentials are used to connect to the new server.
The default value is frNever (0). In this case, redirects are never followed, and a runtime error is generated instead.
HTTPMethod Property (REST Connector)
The HTTP method used for the request.
Data Type
Enumeration
Possible Values
DELETE (0)
GET (1)
POST (2)
PUT (3)
PATCH (4)
Default Value
1
Remarks
This property specifies the HTTP method to use when making a request to the server. Possible values are:
- DELETE
- GET (default)
- HEAD
- POST
- PUT
- TRACE
When set to POST or PUT see RequestParams and PostData for details about sending data to the server.
To specify a different HTTP method set CustomRequestMethod.
HTTPProxy Property (REST Connector)
A set of properties related to proxy access.
Data Type
ProxyRemarks
This is a Proxy type property which contains fields describing the proxy through which the connector will attempt to connect.
HTTPVersion Property (REST Connector)
The HTTP version to use.
Data Type
String
Default Value
"1.1"
Remarks
This property specifies the HTTP version used by the connector. Possible values are:
- "1.0"
- "1.1" (default)
- "2.0"
HTTP/2 Notes
When using HTTP/2 only secure (TLS/SSL) connections are currently supported. Attempting to use a plaintext URL with HTTP/2 will result in an error.
If the server does not support HTTP/2 the connector will automatically use HTTP/1.1 instead. This is done in order to provide compatibility without the need for any additional settings. 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 prior to 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.
LogFile Property (REST Connector)
The file to write logging information to at runtime.
Data Type
String
Default Value
""
Remarks
To write logging information to a file instead of using the connector's logging API, set this property to a valid file on disk and set the LogType property to "File".

Defines a set of configuration settings to be used by the component.
Data Type
String
Default Value
""
Remarks
The connector accepts one or more 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 connector, access to these internal properties is provided through the Other property.
The Other property may be set to one or more configuration settings (name/value pairs). Set one setting per line.
For example:
configname1=value1
configname2=value2
OtherHeaders Property (REST Connector)

Data Type
String
Default Value
""
Remarks
This property optionally specifies headers to be included in addition to the headers generated by the connector. The headers specified should be valid HTTP headers following the format:
Header: Value
To specify multiple headers enter one header per line. For instance setting:
X-Header1: Value1
X-Header2: Value2
Will result in a request with the following headers:
GET / HTTP/1.1
Host: www.nsoftware.com
Accept-Encoding: gzip, deflate
User-Agent: IPWorks HTTP Component - www.nsoftware.com
Connection: close
X-Header1: Value1
X-Header2: Value2
Password Property (REST Connector)
A password if authentication is to be used.
Data Type
Password
Default Value
""
Remarks
If HTTP Basic Authentication is used to authenticate the user, User and Password are Base64-encoded.
If HTTP Digest Authentication is used to, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.
PostData Property (REST Connector)
The data to be posted to the server.
Data Type
String
Default Value
""
Remarks
This property optionally specifies the raw data to be posted to the server.
If set, this property defines the entire HTTP body to be sent to the server. This is only applicable when the HTTPMethod is set to POST or PUT.
In the HTTP Sender, the %MessageBody% macro can be used to include the contents of the incoming BizTalk message in the PostData property. The connector replaces this macro with the full BizTalk message body at runtime.
ContentType may be set to define a Content-Type header. No Content-Type header is set by default when PostData is set.
If specified both RequestParams and ContentFilename properties are ignored.
RequestParams Property (REST Connector)
Parameters to add to the POST or PUT request.
Data Type
String
Default Value
""
Remarks
The RequestParams property specifies one or more parameters to add to the POST or PUT request. This property is only applicable when the HTTPMethod property is set to POST or PUT.
To specify additional parameters set this property to one or more name value pairs. Set one pair on each line. For instance:
name1=value1
name2=value2
The connector will format a request with parameters slightly differently depending on whether the request is made by the Send or Receive adapter.
Note: To have complete control over the data being sent set PostData instead.
ResponseXPath Property (REST Connector)
This property may be set to traverse elements within the JSON document.
Data Type
String
Default Value
""
Remarks
Parsing the Response
The ResponseXPath property may be set to traverse elements within the JSON document. This property implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML document. When this property is set, the connector will parse the response and return the value at the specified location.
For example, let's say the response data from the original request is below.
{
"bag": {
"name": "fanny-pack",
"items": ["camera", "wallet"],
"description": "A hip new design by nsoftware"
}
}
The ResponseXPath property supports both XPath notation and JSONPath notation. For simplicitly, only the XPath notation is shown below. For more information and examples on notation schemes please see "Getting Started with JSON".
If you would like to return the value of element "name" from the operation, then set ResponseXPath to /json/bag/name/. Likewise, if you would like to return the value of the first element of the "items" array, then we can set ResponseXPath to /json/bag/items/[0]/ and the output will be camera.
RuntimeLicense Property (REST Connector)
Specifies the component runtime license key.
Data Type
String
Default Value
""
Remarks
You can use the RuntimeLicense property to set the runtime key for the connector license.
SSLAcceptServerCert Property (REST Connector)
Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.
Data Type
CertificateRemarks
If it finds any issues with the certificate presented by the server, the connector will normally terminate the connection with an error. You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.
This property is used to set a Public Key Certificate.
Ordinarily, the system will attempt to locate the public key in trusted certificate stores in the system registry. If a match is found, the certificate is trusted, and the process proceeds without error. If the certificate is not trusted, the connector will report an error.
You may explicitly set a public key, either to accept a key that is not installed on the system, or to ensure that a specific key is presented. Public key certificates may be loaded from the machine registry or from file.
Note: You may also set the Accept Any field to Yes without opening the certificate selection dialog to force the connector to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes. Set the LogMode to Info to cause the connector to report the server's credentials to Location.
SSLCert Property (REST Connector)
The certificate to use for client authentication during the SSL handshake.
Data Type
CertificateRemarks
This property is used to assign a specific certificate for SSL client authentication.
This field is used to set a Private Key Certificate.
Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format.
StatusCode Property (REST Connector)
The response status code of the last server response.
Data Type
String
Default Value
""
Remarks
This property holds the status code of the server response, such as 200. This indicates the status of the request. This is set as an attribute on the outgoing message.
This property is read-only.
StatusLine Property (REST Connector)
The first line of the last server response.
Data Type
String
Default Value
""
Remarks
This property holds the first line of the server response. This indicates the status of the request. This is set as
an attribute on the outgoing message.
For instance:
HTTP/1.1 200 OK
.
This property is read-only.
TempPath Property (REST Connector)
A temporary local directory where data can be stored before the component processes it.
Data Type
String
Default Value
""
Remarks
This property indicates a temporary directory where the connector can store any data before the connector processes it. If TempPath is empty, the connector will receive all data to memory. If set, the connector will generate and write all inbound data to a temporary file in the specified directory.
Once the file is submitted, the connector will handle closing the file stream and deleting the temporary file. However, if the connector is shut down during a transfer some temporary files may be left in the directory. To ensure optimal performance, server administrators should check the directory regularly and remove old or extraneous files. Note: by default, this property is empty and the connector will use memory streams to store all inbound data before submitting it. It is recommended that you use a temporary directory when downloading large batches or batches containing large files to alleviate potential increased memory requirements.
This property is not available in the Sender.
Timeout Property (REST Connector)
A timeout for the component.
Data Type
Integer
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 connector will wait for the operation to complete before returning control.
If Timeout expires, and the operation is not yet complete, the connector fails with an error.
Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when data is successfully sent or received.
Optionally, the behavior of the connector may be changed to absolute timeouts, i.e. the connector will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.
This behavior is controlled by the AbsoluteTimeout configuration setting.
The default value for the Timeout property is 60 (seconds).
TransferredHeaders Property (REST Connector)
The full set of headers as received from the server.
Data Type
String
Default Value
""
Remarks
This property holds the HTTP headers as received from the server. This may be queried after an operation completes to inspect the response headers.
This property is read-only.
URL Property (REST Connector)
The URL to which the request is made.
Data Type
String
Default Value
""
Remarks
This property specifies the URL to which the request is made. TLS/SSL will be used if and only if the URL scheme is "https".
User Property (REST Connector)
A user name if authentication is to be used.
Data Type
String
Default Value
""
Remarks
If HTTP Basic Authentication is used to authenticate the user, User and Password are Base64-encoded.
If HTTP Digest Authentication is used to, the User and HTTPPassword properties are used to respond to the HTTP Digest Authentication challenge from the server.
Certificate Type
The digital certificate being used.
Remarks
This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.
Fields
Store
String
Default Value: "MY"
The name of the certificate store for the client certificate.
The StoreType field specifies the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.
Store is used in conjunction with the Subject field in order to specify client certificates. If Store has a value, and Subject is set, a search for a certificate is initiated. Please refer to the Subject field for details.
Designations of certificate stores are platform-dependent.
The following are designations of 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. |
SPC | Software publisher certificates. |
In Java, the certificate store normally is a file containing certificates and optional private keys.
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. PKCS12 certificate store).
If the provider is OpenSSL, the certificate store is a file containing a certificate and a private key. This property must be set to the name of the file.
StorePassword
String
Default Value: ""
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.
StoreType
CertStoreTypes
Default Value: 0
The type of certificate store for this certificate.
The connector supports both public and private keys in a variety of formats. When the cstAuto value is used, the connector will automatically determine the type. This field can take one of the following values:
0 (cstUser - 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 (cstMachine) | For Windows, this specifies that the certificate store is a machine store.
Note: This store type is not available in Java. |

Subject
String
Default Value: ""
The subject of the certificate used for client authentication.
When this property is set, a search is performed in the current certificate store certificate with matching subject.
If an exact match is not found, the store is searched for subjects containing the value of the property.
When setting the property to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US
Example (Searching with partial subject)
Control.CertSubject = "Test"

The special value "*" picks a random certificate in the certificate store.
If a matching certificate is found, Subject is set to the full subject of the matching certificate.
Thumbprint
String (read-only)
Default Value: ""
The thumbprint of the certificate.
This field is used to specify the thumbprint of the certificate. When there are multiple certificates in the store that have the same subject, the thumbprint will be used to distinguish between them.
Firewall Type
The firewall the component will connect through.
Remarks
When connecting through a firewall, this type is used to specify different properties of the firewall such as the firewall Host and the FirewallType.
Fields
AutoDetect
Boolean
Default Value: False
Tells the connector whether or not to automatically detect and use firewall system settings, if available.
FirewallType
FirewallTypes
Default Value: 0
Determines the type of firewall to connect through. The applicable values are the following:
Host
String
Default Value: ""
Name or IP address of firewall (optional). If a Host is given, requested connections will be authenticated through the specified firewall when connecting.
If the Host field is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the Host field is set to the corresponding address. If the search is not successful, an error is returned.
Password
String
Default Value: ""
A password if authentication is to be used when connecting through the firewall. If Host is specified, the User and Password fields are used to connect and authenticate to the given firewall. If the authentication fails, a trappable error is fired.
Port
Integer
Default Value: 0
The TCP port for the firewall Host. See the description of the Host field for details.
Note that the Port is set automatically when FirewallType is set to a valid value. See the description of the FirewallType field for details.
User
String
Default Value: ""
A user name if authentication is to be used connecting through a firewall. If the Host is specified, the User and Password fields are used to connect and authenticate to the given Firewall. If the authentication fails, a trappable error is fired.
OAuthAuthorizationParam Type
This type holds details of the OAuth authorization.
Remarks
This type holds details of the OAuth authorization.
Fields
AuthorizationScopes
String
Default Value: ""
A space separated list of scopes as defined by the authorization server.
AuthorizationString
String
Default Value: ""
The OAuth Authorization string. This field holds the current OAuth authorization string. This is retrieved during the OAuth authorization process and is used to authenticate the request. This is a string like:
Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ
CacheLocation
String
Default Value: ""
The location on disk of the OAuth Cache File.
This field specifies the location on disk of the OAuth cache file. This file holds OAuth credentials that may be automatically used during runtime and by other ports using the same provider. The connector uses the data within the cache file to automatically refresh expired tokens at runtime. Do not alter the contents of the file directly.
One file for each provider is used by default. For instance for Box the value is:
%APPDATA%\nsoftware\CloudStorage BizTalk Adapter\BoxOAuthCache.txt
This value may be specified manually as well.
CallbackURL
String
Default Value: ""
The Callback URL used during OAuth authorization.
This field specifies the local URL to which the browser is redirected when initially performing authorization. When initially establishing Authorization set this value to the redirect URI that is registered for your application with the service provider. For instance "http://localhost:7777".
The connector will parse this URL and start a small embedded web server on the specified port to receive the OAuth response from the provider during OAuth authorization.
This value is required to perform OAuth authorization.
ClientId
String
Default Value: ""
The id of the client assigned when registering the application.
This field holds the id of the client that was assigned when initially registering the application.
This value is required to perform OAuth authorization.
ClientSecret
String
Default Value: ""
The secret of the client assigned when registering the application.
This field holds the secret of the client that was assigned when initially registering the application.
This value is required to perform OAuth authorization.
ExpiresIn
Integer
Default Value: 0
The expiration time of the current OAuth authorization string.
This value is populated after OAuth authorization and holds the expiration time of the OAuth access token as reported by the service provider. This is used at runtime to calculate whether the token should be refreshed before attempting an operation. If the token is expired the connector will automatically refresh the token. If the token is not expired the connector will use the current token.
This value should not be set manually.
Note: Not all providers provide this value. For instance Dropbox access tokens never expire.
RefreshToken
String
Default Value: ""
The refresh token received from or sent to the authorization server.
This field holds the refresh token received during the initial OAuth authorization. It is used by the connector to automatically request a new AuthorizationString when the current value expires.
ServerAuthURL
String
Default Value: ""
The URL of the authorization server.
ServerTokenURL
String
Default Value: ""
The URL of the token server.
ServiceProvider
String
Default Value: ""
The service provider to authenticate with.
This field defines the service provider. This is used when performing OAuth authorization. OAuth authorization is only applicable to some providers. If the provider does not support OAuth a warning will be displayed. Possible values when using the Email connector are:
- Gmail
- Other
TimeStamp
String
Default Value: "0"
The timestamp of the OAuth authorization string.
This field holds the timestamp of when the AuthorizationString was retrieved. This is used in conjunction with ExpiresIn to calculate if refreshing the token is required. For more details see ExpiresIn.
This value should not be set manually.
Proxy Type
The proxy the component will connect to.
Remarks
When connecting through a proxy, this type is used to specify different properties of the proxy such as the Server and the AuthScheme.
Fields
AuthScheme
ProxyAuthSchemes
Default Value: 0
Use the AuthScheme field to tell the connector which type of authorization to perform when connecting to the proxy. This is only used when the User and Password fields are set.
AuthScheme should be set to authNone (3) when no authentication is expected.
By default, AuthScheme is authBasic (0), and if the User and Password fields are set, the component will attempt basic authentication. If AuthScheme is set to authDigest (1), digest authentication will be attempted instead.
If AuthScheme is set to authProprietary (2), then the authorization token will not be generated by the connector. Look at the configuration file for the connector being used to find more information about manually setting this token.
If AuthScheme is set to authNtlm (4), NTLM authentication will be used. This option is only available in the SSL package.
For security reasons, setting this property will clear the values of User and Password.
AutoDetect
Boolean
Default Value: False
Tells the connector whether or not to automatically detect and use proxy system settings, if available.
Password
String
Default Value: ""
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.
Port
Integer
Default Value: 80
The TCP port for the proxy Server (default 80). See the description of the Server field for details.
Server
String
Default Value: ""
If a proxy Server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.
If the Server field is set to a Domain Name, a DNS request is initiated and upon successful termination of the request, the Server field is set to the corresponding address. If the search is not successful, an error is returned.
SSL
ProxySSLTypes
Default Value: 0
Determines when to use SSL for the connection to the proxy. The applicable values are the following:
psAutomatic (0) | Default setting. The connection to the Server is SSL-enabled for 'https' URL-s, and non SSL-enabled for other URL-s. |
psAlways (1) | The connection is always SSL-enabled. |
psNever (2) | The connection is not SSL-enabled. |
psTunnel (3) | The connection is through a tunneling (HTTP) proxy. |
User
String
Default Value: ""
A user name, 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.
Config Settings (REST Connector)
The connector 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 connector, access to these internal properties is provided through the Other property.REST Config Settings
The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.
When true, the connector adds an "Accept-Encoding" header to the outgoing request. The value for this header can be controlled by the AcceptEncoding config. The default value for this header is "gzip, deflate".
If set to True (default) the connector will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False the connector fails with an error if the server does not support HTTP/2.
The default value is True.
The format of the date value for IfModifiedSince is detailed in the HTTP specs. An example is:
Sat, 29 Oct 2017 19:43:31 GMT.
The format of this setting consists of a range of bytes specified by two numbers separated by '-' (e.g. "0-499")
For example:
First 500 bytes | 0-499 |
Second 500 bytes | 500-999 |
Final 500 bytes | -500 |
The default value is ture.
The default value is true.
Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.
Override the default with the name and version of your software.
SSL Config Settings
If set to true, the connector 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 connector is the same.
Please note that this setting contains the minimum cipher strength requested from the security library.
Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the connector 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.
Example values when UseInternalSecurityAPI is False (default):
// The "Other" property could contain ONE of the following lines:
SSLEnabledCipherSuites=*
SSLEnabledCipherSuites=CALG_AES_256

If SSLEnabledProtocols is configured to use TLS 1.3 the following values are supported:
- TLS_AES_128_GCM_SHA256
- TLS_AES_256_GCM_SHA384
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) (Experimental) |
TLS1.2 | 3072 (Hex C00) (Default) |
TLS1.1 | 768 (Hex 300) (Default) |
TLS1 | 192 (Hex C0) (Default) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.
Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.
If set to True all certificates returned by the server will be present in the transport log. This includes the leaf certificate, any intermediate certificate, and the root certificate.
Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.
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 not-matching server name). |
When specified the connector 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 connector will fail with an error.
The format of this value is a comma separated list of hash-signature combinations. For instance:
// The "Other" could contain ALL of these lines:
UseInternalSecurityAPI=true
SSLEnabledProtocols=3072
TLS12SignatureAlgorithms=sha1-rsa,sha1-dsa,sha256-rsa,sha256-dsa
The default value for this setting is "sha1-rsa,sha1-dsa,sha224-rsa,sha224-dsa,sha256-rsa,sha256-dsa,sha384-rsa,sha384-dsa,sha512-rsa,sha512-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 UseInternalSecurityAPI is set to True, 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:
- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1"

General Config Settings
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the connector initiate connections (or accept in the case of server connectors) only through that interface.
If the connector is connected, the LocalHost configuration 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).
By default, this config is set to false.
Setting this configuration setting to True tells the connector to use the internal implementation instead of using the system security libraries.
This setting is set to False by default on all platforms.
