When it comes to axing dead endpoints, I see two ways to handle this based on the way webhooks are configured. * If webhooks are configured by UI, then you have to contact the user and tell them their webhook is gone, e.g. via email. * If webhooks are configured programmatically, then the endpoints ought to be able to be swept up silently, and the receiver should know to periodically refresh the configuration for as long as it cares about it. Ideally all webhook implementations would work the second way, but unfortunately it is not standard practice.
