I feel like I am getting closer on this but I need some advice. I have been able to get a SSO token from our server using OAuth 2 (client id, secret, etc). I am using the client information set up for our Epicor SSO client.
My question is now how do I apply that to get the REST API calls to work? I have tried running the call with the bearer token generated but that doesn’t work. I have tried to get a token using GetAccessToken with the generated token and that does not work either. No matter what I try I get the error: IDX10231: Audience validation failed.
I am working on all this is Postman just to figure out the proper sequence of calls.
