I\'m trying to use the Power BI REST API, using an access token acquired with the \"client credentials\" method, but I keep getting 403 Forbidden on my requests
This is not an answer but one step forward in the debug process. I think the resource for which the token is requested should be "https://analysis.windows.net/powerbi/api". I've seen these in multiple references; one of them is linked below. Even after changing this, I still get a 403. As the OP mentioned if we use the accessToken from the powerBI portal, everything works.
