A webhook (also called a web callback or HTTP push API) is a way for updatedge to provide other applications with real-time information. A webhook delivers data to other applications as it happens, meaning you get data immediately.
The platform uses webhooks to provide you with alerts to events that you might want to react to. In order to do this you need to provide the base url of the publicly exposed endpoint you want updatedge to call and implement the endpoint according to the supplied specification.
You must implement both service availability webhooks before you implement any others to ensure that updatedge knows your webhooks are functionality properly and are available.
