Duplicate Zoom Phone Webhook Events
We’re currently receiving duplicate webhook events for the following webhooks:
- phone.callee_ringing
- phone.callee_answered
- phone.recording_completed
- phone.recording_transcript_completed
By far the worst culprit is the transcript endpoint. Since a platform release to Zoom on 19th, we’re now seeing 40 to 50 duplicate event messages per call. All raw event messages are identical apart from the “event_ts” value. These are all extremely close together, often just milliseconds apart.
We’re doing our best to block duplicates but this isn’t always possible.
Zoom Support are refusing to help here even though I see it as a platform issue and not a developer issue. Our logs clearly show a huge increase in events since 19th May.
Has anyone else experienced this issue? We’re seeing identical behaviour in multiple Zoom accounts.
How To Reproduce
Steps to reproduce the behavior:
*1. Create a server to server OAuth app
*2. Subscribe to Zoom Phone webhooks as listed above
*3. Add an endpoint to consume the webhooks
*4. Validate the webhooks
*5. Make Zoom phone calls
*6 Duplicate webhook events are received
Has anyone else seen this, and does anyone know how we can get Zoom Support to take this issue seriously, please?
Thanks for your help,
Ben
