We expect your webhook endpoint to respond to webhook requests with a 2XX status code within three seconds. Non-2XX responses, or responses that take more than three seconds, will be considered failures.

If your server fails to reply with the a 2XX status code, we will retry the webhook request up to four times – first after 10 seconds, then a further 30 seconds, a further 120 seconds, and finally a further 300 seconds. If after four retries (five attempts total) we still don't receive the 2XX response we will make no further attempts to send this webhook request.
