Ich bekomme immer die Fehlermeldung 403 Forbidden - perhaps check your credentials?
403 - “{\“message\”:\”\“,\“status\”:403}”
Ich habe die Credentials schon neu verbunden/erstellt. Leide keine Abhilfe. Hat jemand Erfahrung damit? Vielen Dank im Voraus und viele Grüße Tobias
Oi @tobiasknebel , Welcome to the n8n community 
I can see that your post is related to a question. The “Feature Requests” category is intended for cases where we want to suggest and vote on improvements to be implemented. Since the community is international, we kindly ask that posts be written in English (there are some announcements about translation that are worth checking out).
That said, your case looks more like the authentication itself succeeded, but the account/app does not have permission to perform the requested operation. To investigate this properly, I would recommend following the guidance and reposting it under the “Questions” category.
If you still need help afterward, feel free to tag me in your reply and I’ll take another look.
