Inconsistent Webhook Delivery

We have webinar webhooks enabled for all webhook created/updated/deleted events, as well as all registration events. However, when we update the webhook via the Zoom platform or Zoom API, or register/cancel a registrant using the Zoom platform or Zoom API, we’re not receiving the webhooks in a consistent manner. Is there a usage quota or any throttling that occurs with webhooks?

Which App Type (OAuth / Chatbot / JWT / Webhook)?

How To Reproduce (If applicable)

  1. Register for a Webinar (webhook maybe delivered)
  2. Cancel webinar registration (webhook maybe delivered)
  3. Update webinar via the API (webhook maybe delivered)

Hi @sdenardi

Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!
Could you please share a webinar ID example where you were able to identify this issue?


Yes! 87204392805 is a recent one.

Thank you for providing that Webinar ID, can you confirm if the reported behavior persists? If so, can you open a ticket directly with our developers by emailing Happy to take a closer to see what may be happening.
