Zoom API and OAuth

Hello guys,

I’m trying to get a phone call summary from Zoom
(Zoom Phone API)

I already set up a webhook getting the event, but I struggle with OAuth of Zoom. OAuth is set up, but I cannot get a token to make a GET request to the API.

I always get a 403 error, altought the scopes are set correct in the OAuth. Seems as I don’t understand something. Maybe someone figured it out?
