Topic Title / Summary
Server-to-Server OAuth app (“Webinar Manager”) stopped triggering and delivering webhook events to validated URL
API Endpoint(s) and/or Zoom API Event(s)
-
webinar.created -
webinar.updated -
(Other previously active webhook events)
Description
We have a live, account-level Server-to-Server OAuth app named Webinar Manager. This integration was working perfectly in the past, but it has suddenly stopped delivering webhook events.
The webhook URL successfully passes validation, but we are receiving absolutely zero inbound HTTP requests on our server logs when an event occurs. We have checked the Zoom Web Portal under Advanced > App Marketplace > Manage > Apps on account > Webinar Manager > Call logs, and there are no call logs or event triggers appearing there on our end.
We have already attempted the following troubleshooting steps with no success:
-
Verified the app is fully Activated/Live and running on the correct testing account.
-
Toggled event subscriptions off and on, added new test events (
webinar.created,webinar.updated), and re-saved the configuration. -
Deactivated and reactivated the app entirely.
Error?
There are no explicit error messages. The webhooks are completely silent—they are not generating dashboard logs and are not attempting delivery to our server.
How To Reproduce
-
Action/Trigger: Create or update a webinar within the Zoom account where the “Webinar Manager” app is authorized.
-
Authentication Method / App Type: Server-to-Server OAuth (Account-level).
-
Observed Behavior: * Navigate to the Zoom Web Portal → Advanced > App Marketplace > Manage > Apps on account > Webinar Manager > Call logs. Notice that no logs are generated for the event.
- Check destination server logs. Notice that no inbound HTTP POST requests from Zoom are received.
