YouTube Data API returns “Access Not Configured” error, although it is enabled

Question

My internally used web solution to retrieve YouTube video statistics that is based on this example (https://developers.google.com/youtube/v3/quickstart/js) now fails to work. No

Answer 1

What seems to have done it for me after a lot of fiddling was to:

1. Go to the OAuth consent screen of the project.
2. Enter an Application name.
3. Press Save.

Lo and behold, after 5 minutes it started working.
