There is no “last broadcast” date that I’m aware of. You’ll probably have to resort to checking /channels/:channel/videos to see if they have any VODs.
TY guys, I did consider trying to fetch the stream endpoint.
Problem is that may not be streaming.
With getting previous VOD’s Twitch by default no longer saves VOD’s unless you change settings manually in options.
I will consider the stream response being null or maybe I just really try to persuade the user that unless your a broadcaster this option is pointless and best left alone… Big red message maybe
