# Resolving webhook delays

<!-- WARNING: THIS FILE WAS AUTOGENERATED! DO NOT EDIT! -->

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**.

In the even of a Zoom Webhook service disruption, please stay updated on
