Client is not authorized to access You need to create a "client-grant" associated to this API

I do not believe w are using this functionality so why would we be getting the error message. We are only authenticating users no M2M

Hey @jon10 welcome to the community!

Sorry for the delayed response, but wanted to check in on this one - Were you ever able to get this sorted?

This error definitely leads me to believe there’s an attempted client credentials exchange going on somewhere. Are you using the Management API at all?

I do not believe we are using the Management API at all. This is a Wordpress Plugin setup. It is very frequent (as in one per minute but slightly irregular). Client is not authorized to access … You need to create a “client-grant” associated to this API.

Could this be an intrusion attempt or something to do with Wordpress?

Hmm, that’s odd - Can you DM me the tenant in question? I’d like to take a look at the logs if possible.
