Webhook
A webhook is an HTTP request a platform sends to your system the moment something happens, so you learn about it immediately instead of asking repeatedly.
Also calledcallback URL
In messaging it is how inbound messages, delivery statuses, and template approvals arrive. Because a webhook endpoint is publicly reachable, the request has to be signature-verified so nobody can forge one. A platform that does not verify signatures on inbound webhooks has an open door, whatever else it does well.
