Webhooks – Frequently Asked Questions
This section answers common questions about Webhooks.
What webhook events are available? Please refer to COS webhooks
Why is my webhook status Suspended? Suspended status means that we could not successfully deliver an event to one of your registrations.
What is the retention period of webhooks? Currently there is no limitation to the retention period. However, webhooks expire after 7 days and cannot be redelivered.
What is the maximum number of resources included in a single webhook event? 50k for events received in basic format 1k for events in extended format.
How are webhook failures handled? After a delivery failure, COS will retry 3 additional times after approximately 30 - 60 seconds before your registration updates to a Suspended status. If we still can't deliver the event after several retries, its registration status changes to Suspended and we start to queue all your events for your registration. No further attempts are made to deliver previous or future events until your registration returns to an Active status.
