Item # 7: "Hint: The relevant documentation about this API call is here: https://dev.twitch.tv/docs/v5/reference/streams/#get-stream-by-user."
I’m going through the process right now and the v5 API is deprecated. From their documentation: “V5 is deprecated as of 8/31/17 and will be removed entirely on 12/31/18 (in favor of the new Twitch API, mentioned above).”
I know Dec 2018 is quite a ways still, but we are past Aug 2017 and they do recommend to start using their new API which is provided.
Also, you do now have to register an app in order to get a client ID, that may already be something people have figured out. I’m just getting started, so forgive me if I’m telling you things you already know. I thought you might want to know about the new API. There is no longer access to an ID through the “connections” tab in the normal user settings - you have to go ahead and sign up for a dev profile, but it’s easy and your regular user login gives you access.
