Hello everyone,
I am currently facing an issue with my Postman request to a BC250 environment.
Environment Details:
- BC250: On-premises installation
- ClientServicesCredentialType: AccessControlService
- Authentication Setup: OpenID Connect with OAuth, successfully configured
When using Postman with the Authorization Code grant type, I can successfully obtain an access token by logging in with my user credentials.
When attempting to obtain an access token using the Client Credentials grant type, I encounter the following error:
Error: invalid_grant, Description: AADSTS501051: Application '<applicationid>' (<applicationName>) is not assigned to a role for the application '<applicationid>' (<applicationName>)
Steps Taken:- Confirmed that OpenID Connect and OAuth are correctly set up.
- Verified that the Authorization Code grant type works without issues.
Does anyone know how to resolve this issue? Specifically:
- Is there a missing configuration in Azure AD or Business Central that could be causing this?
- Do I need to assign specific roles or permissions to the application for Client Credentials to work?
Any insights or guidance would be greatly appreciated!
Thank you in advance.
