I am able to procure the auth token with Client_ID and Client_Secret with Granttype= Authorization Code (UserId and Password) When I configured Postman to Procure the Token with just Client_ID and Client_Secret with Granttype=Client Credentials, I am able to get the token, but When I use the Token I cannot access the API. Getting a "diagnostics": " Authentication failed. " error.

FHIR API Access - Cannot access api when the token is procured - with Granttype=Client Credentials (No userID/Password)

Hello @Satish Cheepurpalli - Are you still hitting this issue? Could you verify if the same Azure AD endpoints are being used per this section when attempting to use the token against the resource API? Also, have you tried validating the token identity provider as well as the claims as per this doc for troubleshooting?
