The New Twitch API needs serious attention. I worked considerable with the V3 API and that was rock solid. I'm having a difficult time with the new API. It has a lot of quirks.

My biggest issue now is that certain calls return an empty response with certain parameters.

For example, if I try to filter streams with a gameid and language this will return a result with 0 items sometimes while other times it will return the correct results. The behavior is very inconsistent.
https://api.twitch.tv/helix/streams?gameid=33214&language=en

It works 100% of the time without the language parameter.
https://api.twitch.tv/helix/streams?game_id=33214

It will also filter incorrectly if the parameters are not entered in alphabetical order which is not documented.

Allow game developers to rename a game without going through customer support agents.

Right now I am trying to go through the process of updating the game name, and it has been a **** for 6 months already. Took a month go get the update happen on GiantBomb, waited few months for Twitch to synchronize, which didn't happen, then started writing to support agents.

First reply to my ticket was 2 months after I opened it. Support replied with a canned response about renaming a user...

After reopening the ticket, several weeks later I get the ticket closed again, with another canned response, this time about adding a new game.

Reopened the ticket a third time, still waiting for next response for weeks, feeling hopeless.

Renaming a game seems a simple operation, it could be performed through the creator dashboard after you claim the game, just like you'd change the box art.

Such a feature would save me a ton of grey cells. Right now I'm not sure if the game will ever be streamed properly, if it won't get renamed before launch...

There are two scenarios when using this API which return a 500 from the server, but which should return either a 401 or 400 and a meaningful error code to help point out the issue:

1. If you have set your productSKU's to 'live', but you're testing in 'Hosted testing', you receive this error. A response telling you that you cannot test SKUs in live mode when in hosted testing would be great.




2. If your extension is live and you are trying to use bits on a channel which doesnt support it, you will receive a 500 from the server. I understand that this 'isnt supposed to happen' since you shouldnt be allowing any bits transactions on a channel which isnt bits authorized, but still a more helpful message can be returned as this mistake can happen and doesnt help the dev understand clearly whats wrong.

It is quite hard to find clips using hard https://www.twitch.tv/manager/clips page to find clips and API does not offer nice solutions to make a 3rd party application to replace it.
Here are some examples of API request parameters and some of their possible uses.

curator_id:
- clip creator can find all their own clips
- broadcaster can find and delete all the clips from problematic viewer

vod_id:
- find clip compilation material for the stream

created_at:
- find clip compilation material for the date(and range)
- find throwback clips - "last year this time we did this"

broadcaster_id:
- in combination with others would make the API request more useful
