When calling the endpoint https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarupdate, I notice that the host (not the registrants, just the host) gets a confirmation email resent to him again every time.
Why is this so? When I edit the webinar in the Zoom web portal, it doesn’t happen.
Hey @nelson,
Can you send me your request body so I can reproduce?
Also what are your webinar registration related settings?
Thanks,
Tommy
Hi - I’m sorry about this one. The problem is at our end. We are doing a user registration of the host at the same time, hence the confirmation is being sent.
No worries! Glad you figured it out!
