Delivery#

Cloud now blocks webhook delivery to endpoints that resolve to private or internal network addresses. Attempts to deliver to such URLs will fail immediately with a network error rather than timing out or returning an HTTP error. This affects any customer whose webhook endpoint URL resolves to a loopback, link-local, or other non-public IP address; those deliveries will be recorded as failed and will be retried according to the normal retry schedule.
