Cloud Recording Webhook Events Not Being Delivered Despite Successful Endpoint Validation

API and Webhooks
1

Hi Team,

We are facing an issue with Zoom webhook event delivery for cloud recordings.

Issue Description

Meeting recordings are being successfully generated and stored in Zoom Cloud. However, our application is not receiving the corresponding webhook events (specifically the Cloud Recording Completed event).

As a result, our system is unable to process recordings after the meeting ends.

Current Behavior

  • Cloud recordings are successfully available in Zoom Cloud.
  • Webhook URL validation requests are successfully received and validated by our API.
  • Other endpoint connectivity checks appear to be working.
  • Only the actual webhook event notifications are not being delivered.

Background

We encountered a similar issue previously. At that time, we created a new Zoom App and reconfigured all webhook subscriptions. After migrating to the new app, webhook events started working correctly again.

However, the same issue has now reoccurred, and webhook events have stopped arriving even though recordings continue to be generated successfully.

What We Have Verified

  1. Cloud Recording feature is enabled.
  2. Recordings are successfully generated and stored in Zoom Cloud.
  3. Webhook event subscription for recording completion is enabled.
  4. Webhook endpoint is reachable from Zoom.
  5. Endpoint URL validation requests are received successfully.
  6. No changes have been made recently to the webhook endpoint implementation.

Questions

  1. Is there any known issue that could cause Cloud Recording webhook events to stop being delivered while endpoint validation continues to work?
  2. Has anyone experienced a similar issue where recreating the Zoom App temporarily resolved the problem?

Any guidance would be greatly appreciated.

Thank you.

@argusclass01 did you change the webhook endpoint URL on your production tab? If you did, you will to resubmit the application for verification.

No, I did not change the webhook endpoint URL in the Production tab. However, to rule out any verification-related issues, I re-verified the endpoint URL and completed the verification process again.

@argusclass01 I’ll PM you on this as I need to share some PII information.
