Can anyone advise on how to get channel is hosted notifications? The common responses seem to be to use this 3rd party API - https://tmi.twitch.tv/hosts?include_logins=1&target=501071947 - unsure if I’ve formatted my query incorrectly, but all I’m getting is a 404 response even when the streamer (ID 50107947) is online and I know at least on channel is actively hosting!
Currently there is no good way to get “inbound” Hosts.
What you linked to was removed and was a undocumented endpoint not intended for third parties to use
