Failed Webhooks Support Failure Notification Emails
When the webhook cannot be delivered to the target URL, an email will be sent to the provided email(s) describing the reason for the delivery failure. This typically only happens when the target URL times out or returns a HTTP response with a status code greater than HTTP 200.
In the past, webhook delivery failures were silent. So you had to rely on your own monitoring and error reporting to notice the issue. This new feature makes it much easier to detect and react to webhook delivery errors.
