I did decode that earlier message – the admin on our end had set the webinar to close reg after the date had passed. We created a new test webinar, but have run into a new issue.
With an on-demand webinar, that has registration open beyond its close date:
If you register an attendee via API after the close date
Zoom sends you an email that contains a Join Webinar link
Clicking this link takes the user to this screen/error message:
Thank you for reaching out to the Zoom Developer Forum. This does seem to be an issue with how Zoom responds to adding a registrant after the webinar ends.
Please send an email to developersupport@zoom.us with a link to this thread. In that email, please include the webinar ID where you saw this as well as the email address you tested with where you saw that we sent a Webinar Join Email.
I’ll work with our engineering team to see if we can change the email that goes out in this circumstance.
