Getting multiple webhook events called on app?

[ron.jailall (Ron)]

Description
It doesn’t happen all the time, but for various users of our app, we’re sporadically seeing multiple calls from Zoom to the webhook endpoint indicating that a recording has been completed, for the same recording.
Error
No corresponding error

Which App?
https://marketplace.zoom.us/apps/lg4d4gEQTryxrPRvdAj75g

Additional context
For 1 user the first webhook came in at 21:45 and the second came in at 21:48. They had the exact same webhook URL for recording.completed

For another user it was 2020-08-14 14:36:52.497 and 2020-08-14 14:31:11.213.

Is there any reason this would be the case?

Hey @ron.jailall,

Can you confirm you are sending a 200 OK response back within 3 seconds after you receive the webhook?

If you do not send this response back, Zoom thinks the webhook failed to send, and tries again later.

Thanks,
Tommy
