Error 403 Rest Connector

Hi All,


I am unable to connect to an external services via REST connector with an Authentication Profile configured with an Oauth 2.0 Provider with Client Credentials Grant Type, Basic authentication scheme, configured an access token endpoint URL and send token access in header.

With the above mentioned configuration provided by the API market where the Rest services are exposed. I always get a HTTP Status Response 403 Forbidden.

If i try from postman with the same configuration i can get the access token properly with the same client ID and Credentials and get a proper response from the service.


I wonder whether i am missing some kind of Auth profile, Oauth 2.0 Provider rule or i can use Pega Rest connector to achieve this as it is not implemented to use this type of configuration with Client Credentials obtaining access token through endpoint url.


Please have a look at the attached document with screenshots of exception, log files, tracer some questions and my final conclusion.


Any help on this would be much appreciated. It is urgent for us to connect to this external Rest service.
