Webhooks Reference

How they work

Webhook URLs will receive a POST request with JSON data related to the event that triggered the webhook.

See Events below for supported events and the associated JSON payloads.

Error handling

There are things that can go wrong even before a request reaches its destination (e.g. DNS resolution error, sudden network failure, etc.) and even if it does, the target system may not always be able to correctly process the request. This is why the notification delivery system is built to handle these failures.

Our webhook delivery system uses response status to determine whether a request has been successful or not.

• 2XX response codes: The request is considered successful and the notification is considered as delivered, no retry needed.

• Any other response status or error (such as connection error, timeout, etc.) is handled as an unsuccessful delivery attempt and the task is rescheduled for later.

Retries

If a webhook delivery fails, it gets retried. We use an exponential backoff strategy to determine how long to wait before attempting the delivery again.

We'll retry a webhook delivery up to 14 times (~24 hours of retrying), after which the delivery will be marked as retries exhausted and retries will stop.
