Graph API unauthorized_client: The client does not exist or is not enabled for consumers.

Question

I registered an app with organization (non-personal). When trying to get authorization, I got "unauthorized_client" error. I did setup localhost as redirect URI and here are the API permission

Do I need to Expose the API and authorize the client?

Answer 1

Just to be sure, have you replaced 'consumers' text by your tenant id in the request URL?

Hello,

Could you show us the app registration configuration? Authentication and API permissions panels to begin.

And the request url you use as well, I wonder which OAuth flow you specify.
