I just executed a batch job which fetches users’ current display names.
It queries the endpoint at https://api.twitch.tv/helix/users about 50 times with the max of 100 IDs per request.
About 5 minutes later, all of my developer applications disappeared from my developer dashboard (extensions are still there).
Furthermore, I get 401 Unauthorized with every request now.
The refresh token renewal endpoint still works using my client ID/secret, but the returned (new) access token also results in 401s being thrown at me.
Is this a known issue or am I doing something wrong?
And of course, only a short time after me finally deciding to create this post, it does work again.
Hopefully it was just an unexpected downtime.
I just did surprise me that other applications/users were not affected, I tried several.
