I would like to seek help with the REST API authentication via custom SAML authentication service.
Currently, I have successfully managed to perform a SAML login to PEGA dashboard by using IDP's access token. However, when i turn on the SAML authentication for REST API and i tried to invoke any OOTB API (i.e. GET assignments), I will be shown with the following error.
"Rest service [api][v1][assignments] failed:Requestor authentication failed due to missing credentials"
Am i missing anything here since the same access token can be used to perform login but not web service?
