Ui tab

title	Basic

The Basic tab contains settings related to the location and authentication of the remote server.

REST Client agent configuration - Basic tab

Setting	Description
Base URL	This is the target URL for requests from the REST Client agent. Enter the URL in the following format: `<protocol>://hostname:<optional-port>/<optional-path>` The supported protocols are HTTP and HTTPS. If no port is specified, the agent will default to 80 for HTTP and 443 for HTTPS. Keystore When the protocol in the base URL is set to https, the option to Use TLS will be enabled.
Use TLS	Enable Transport Layer Security for the REST Client agent. This option is configurable when https is set as the protocol in the base URL.
Security Profile	securityprofilesettingtrue

Note!

When the Base URL has the protocol set to https, Use TLS is disabled, and Security Profile is left empty, the REST Client agent will trust all certificates.

Ui tab

title	Advanced

The Advanced tab contains settings related to the HTTP/HTTPS connection and handling of incoming requests.

REST Client agent configuration - Advanced tab

Setting Description

Timeout (ms)

Enter the maximum response time from the remote server in milliseconds.

If the response time from the server exceeds this value, the REST Client agent updates the Error field of the outgoing RESTCycleUDR.

For further information about UDR types, see .

The default value is 5000 ms.

Max Outstanding Requests

Enter the maximum number of outstanding requests that the agent can handle simultaneously. A request that is received by the agent is considered outstanding until a corresponding response is received from the remote server.

If the number of requests exceeds this value, the REST Client agent updates the Error field of the outgoing RESTCycleUDR. New requests are not sent by the agent until the number of outstanding requests decreases.

For further information about UDR types, see .

The default value is 100 requests.

You will also be able to define the max-chunk-size and max-content-length of the requests received by the agent. You can set the properties on the EC running the REST Client agent or on a container that are running the EC's with the REST Client agents. For details on the properties, you can refer to or .

Ui tab

title	Authentication

The Authentication tab contains settings related to the supported authentication types that can be used by the REST Client agent. Different settings are available for the various authentication types. These include:

None - No authentication (default value)
Basic - Authentication according to the 'Basic' HTTP Authentication Scheme (RFC 7617)
OAuth 2.0 - Authentication according to the OAuth 2.0 Authorization Framework (RFC 6749)

None

When you select None in Authentication Type, there are no additional settings.

Basic

Basic authentication requires a username and a password, which are base64 encoded and sent in the header of the request.

When you select Basic in Authentication Type, the following settings are available:

REST Client agent configuration - Authentication tab (basic)

Setting	Description
Username	Enter a username for an account on the remote server. The username must not include colon (:) characters.
Password	Enter the password associated with the username.

OAuth 2.0

RFC 6749 specifies four grant types for authentication. At the time of writing, the only available grant types are "Client Credentials" and "Resource Owner Password Credentials". These types require additional parameters that are sent to an authorization server.

Token Expiry

A request that is using invalid token, e g due to expiry, will fail and an error code will be set in the corresponding RESTCycleUDR that the agent routes back to the workflow. For an expired token, server will send error response that contains header WWW-Authenticate=Bearer,error=invalid_token. The agent will automatically attempt to obtain a new token, but you must configure your APL to resend the failed request.

Settings

REST Client agent configuration - Authentication tab (OAuth 2.0)

When you select OAuth 2.0 in Authentication Type, the following settings are available:

Setting	Description
Grant Type	Select the grant type: Client Credentials The agent fetches the access token from the Access Token URI during initialization, using client id and client secret for basic authentication. The credentials are base64 encoded and sent in the header of the request. The response contains an access token, which is then used in subsequent requests. Resource Owner Password Credentials The agent fetches the access token from the Access Token URI during initialization, using the following credentials for authentication: Client ID Client Secret Username Password The credentials are sent in the body of the request. The response contains an access token, which is then used in subsequent requests.
Client Auth Type	Select the client authentication method: client_secret_basic - The credentials are base64 encoded and sent in the header of the request. client_secret_post - The credentials are sent in the body of the request.
Client ID	Enter the unique client identifier issued by the authorization server.
Client Secret	Enter the client secret.
Username	Enter the resource owner username, i e end-user granting access to a protected resource. This field is required when you have selected Resource Owner Password Credentials from the drop-down list Grant Type.
Password	Enter the password associated with the username. This field is required when you have selected Resource Owner Password Credentials from the drop-down list Grant Type.
Access Token URI	Enter the URI where the access token can be obtained.
Base URL Field	Some authentication servers may provide a base URL in the response body that the REST client agent must use in subsequent requests. When this is applicable, enter the name of the key in the JSON formatted string that holds the base URL. The value extracted from the response overrides, the Base URL, that you have configured in the Basic tab. In the following example, the base URL is available in `instance_url`. Example - Base URL in response from authentication server
Additional Parameters	Some authentication servers may require additional parameters in the body of the token requests. To add a parameter, click the Add button and then enter the name of the parameter in the Key field and the value of the parameter in the Value field. Do not use escape characters in the value field, these will be added automatically by the REST Client agent. For instance, "https://example.com/" will be sent as "https%3A%2F%2example.com%2F".

If you need to have dynamically configurable client credentials for OAuth 2.0, you may also use the OAuth2UDR for this, see for further information.
