Most of the resources are the same as in v3 with a few exceptions. The major difference is that the endpoint URLs will use an ID instead of a username. E.g. https://api.twitch.tv/kraken/users/dallas will now be https://api.twitch.tv/kraken/users/44322889 instead. As mentioned in the post, we’re looking to provide reference docs for the affected endpoints in mid-December. We’ll provide those at https://dev.twitch.tv/docs. Hope that helps!
