Google push notifications - Unauthorized WebHook callback channel

Question

I\'m facing problem with Google push notifications (for drive). I use service account which works perfectly for all other drive operations except drive changes watch.

Answer 1

For me, I wanted the callback webhook URL as https://test-apis.domain.io. So for domain verification, I added test-apis.domain.io and then tried to modify the TXT record but it never was working(validating).

Finally ended up verifying just domain.io with the same method. After this was done I was able to add the domain test-apis.domain.io in the credentials "Domain verification" screen. Hope this helps others as well.
