Explanation

A webhook is an HTTP-based callback mechanism that allows one application to send real-time, event-driven notifications to another application or endpoint. When a specific event occurs in the SD-WAN system (e.g., a link failure or policy change), the SD-WAN controller sends an HTTP POST request to a pre-configured URL on the third-party application. This is different from polling (where the third party would repeatedly query the SD-WAN for updates). Loopbacks are local network interfaces, callbacks are a general programming concept, and APIs require the third party to initiate the request.
