Thanks for the reply Barry. As we are looking for completely unattended automation, I’m not sure if you are suggesting to monitor realtime chat events. The UserVoice articles you reference seem to be requesting the needed features.
I realize now that the HOSTTARGET I mentioned above is from the set of limited IRC Commands. I think what I was looking for is an endpoint in the list at https://dev.twitch.tv/docs/api/webhooks-reference that would report the AutoHost event. My thought was to then be able to notify followers of the event, perhaps by briefly invoking a stream, with the title of the stream as the message to the followers.
Thanks for any more ideas.
