If you haven’t been using an app or user token, you should expect a 30 request per minute rate limit.
If it was at 800 before, it was a problem on Twitch side.
The documentation gives you all the details: https://dev.twitch.tv/docs/api/guide#rate-limits
Solutions:
- use an app token
- optimize your API calls (800 a minute is A LOT, you can probably reduce it)
