Webhook event "webinar.registration_created" not fired

Description
webinar.registration_created event not triggered for a specific Zoom account (the event works well for other accounts).

Registrants added to webinar via create webinar registrant endpoint or manually via webinar registration URL do appear in Zoom, but no event.

Would appreciate any help investigating this issue.

Error
webinar.registration_created event not sent

Which App Type (OAuth / Chatbot / JWT / Webhook)?
OAuth, Account-level app: https://marketplace.zoom.us/develop/apps/rN8lu2ruTQ69vgYVHXZipw

How To Reproduce (If applicable)
A. Create registrant via API call https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantcreate - registrant added, event not fired
B. Register for a webinar via registration URL - registrant added, event not fired

Additional context
Connected Zoom Account ID: B-W39opuRjy880DOK3Su-A
Webinar ID: 418933970 - registration required, auto-approval, 7 registrants so far but no events :frowning:

There are quite a lot of Zoom accounts using our app and webhook events are fired just fine.

The app is subscribed to webinar.ended event as well. I don’t see it in our logs. Actually, I see no events at all (starting from 2020/01/01). Is there any way webhook events might be disabled for an account? Maybe some settings? The permissions should not be an issue since the token was granted by the Owner of Zoom account.

Hey @afrider, thanks for posting and using Zoom!

This sounds like your app was uninstalled by that account/user so you would not be receiving the respective webhooks.

Let me know if you think this issue is different and I will take a look at our logs.

Thanks,

Hey @tommy!

The app is installed - I see successful webinar registrations via API and other Zoom API calls in our logs.

Thanks for looking into this!

Hey @afrider,

What is the App Name? I can’t access the url you shared. Also can you private message me the access_token you have for that user so I can look into if their settings changed?

Thanks,
Tommy

Hey @tommy,

The app is “Zoom for HubSpot” - please try this url: https://marketplace.zoom.us/apps/o8JuTnfNQ3mS5URt2qjp1Q

Hi @tommy!

I’ve got an update here.

We’ve asked the customer to re-install the app and now all the webhook events are fired as expected. I’d suggest that the re-install reset some settings which were blocking events?

I think the priority of the issue is now lower since there is a way to solve it, but knowing the reason and maybe fixing it (if that’s a bug) would still be very welcome.

Thanks,
Alex

Hey @afrider,

Happy to hear reinstalling the app fixed the issue. :slight_smile:

I will still update you on the reason why they stopped in the first place once we find out.

Thanks,
Tommy
