I have pre-registered all attendees for my virtual conference for all live GoToWebinar sessions using Zapier. When it is time for the session, I send them to https://global.gotowebinar.com/join/######### (<- insert 9 digit webinar ID here). They add their email address and are immediately admitted to the webinar. It works like a charm.
Now I have taken recordings and uploaded them as separate On-Demand webinars. I can still preregister people like before, but the only webinar ID I can find is now 18 digits. The URL above does not accept the 18 digit ID. Is there a 9 digit ID for recorded webinars? If so, where do I find it?
