Introduction to Webhooks
Webhooks are a incredibly useful and a resource-light way to implement event reactions.
In essence, Webhooks provide a communication mechanism where a server-side application can notify a third-party server-side application when a new event that the consumer application might be interested in, has occurred on the system.
Webhooks operate on the concept of "event reaction" (don't call me, I'll call you if I have something new), and thus avoids the need for constant polling of the server-side application. Thus, rather than doing your consumer application constantly polling the server-side application to check for new events, the server-side application calls your application by invoking a client provided webhook URL via HTTP protocol anytime the server-side has something new to report.
