Retrieving recent requests…

A webhook (also called a web callback or HTTP push API) is a mechanism that enables an app to provide other applications with real-time information. When you configure a webhook with webHookType set to HTTP, the system sends event notifications as HTTP POST requests to the specified webhook URL. If you configure webHookType as QUEUE_INT, events are published to an internal queue and are not delivered to external endpoints via HTTP callbacks.
