Hello,

I have a question on the new online management API for D365 admin portal. Can we use the Admin API's with Client Credentials grant flow? The steps mentioned in the Developer Guide(https://docs.microsoft.com/en-us/dynamics365/customer-engagement/developer/online-management-api/authentication) uses the Authorization Code flow, prompting the user to validate with his credentials.

I have my client Id and secret from the app registered and trying to call https://admin.services.crm.dynamics.com/api/v1/Instances API

I am able to get the token, but getting an Authorization error when making the call to the API.

Does it only support Authorization Code grant flow?

RE: Support for Client Credentials grant flow for Online Management API for Dynamics 365

I ran into similar situation today.

I guess the problem is the Authority (https://login.windows.net/common/oauth2/authorize/) is trying to look for an App in dynamics.com tenant but the app is registered in our O365 tenant. I am getting this error during the token generation.

* AADSTS70001: Application with identifier '<ApplicationID>' was not found in the directory dynamics.com

If I change the Authority to use my O365 tenant ID instead of 'common', a token is successfully generated, however, it throws an Authorization error.
