I’m not sure if you could elaborate on getting NOTICE’s / Raw from TwitchChat; I’ve searched around and haven’t been able to find anything that seems to shed light on how to do that.
Here’s the full output of my program, with the indented lines being the requests sent to the websocket, and the not indented lines being any and all non-PING responses received from the server. https://hastebin.com/eludagiyet.rb
Although, this might all be a bit moot, because it seems like Twitch has 2 more (?) APIs, and it seems this one is indeed going away by the end of the year (or not?).
