Hey folks, I’m the PM on Schedule at Twitch who has been working with the Helix team for some of these.
The iCal endpoint is something we specifically had in mind for streamers who aren’t building their own API integrations to easily be able to connect their Twitch stream schedule into calendar applications to make it easy to see when they planned to stream relative to the rest of their other life events.
We’ll be exposing it in the dashboard in a way that makes it easy for them to connect soon. We just have a bit more testing and iteration to do on it.
