Webhook Delays can be cause by Zoom not receiving a 200 OK response from your Event Notification Endpoint URL after you receive a Webhook.
After receiving a Webhook, your Event Notification Endpoint URL should respond with either a 200 or a 204 HTTP status code within three seconds for Zoom to consider that the notification was successfully delivered.
In the case where a 200 OK response is not received, Zoom assumes the Webhook request failed, and will send it 3 more times. The first retry will be sent 5 minutes after the initial notification delivery attempt, second retry will be sent 20 minutes after the first retry attempt and third retry will be sent 60 minutes after the second retry attempt for an event. If a 2XX response is received after one of these attempted retries, the event notification will continue to be sent as usual. However, if Zoom doesn’t receive a 2XX response even after executing all three retries, no further notifications related to that event will be sent to your app’s Event Notification Endpoint URL.
To reset the retry count, please submit a ticket.
In the even of a Zoom Webhook service disruption, please stay updated on status.zoom.us.
