What is it?

Webhooks are a mechanism to listen and react to events using an HTTP callback: an HTTP POST that occurs when an event occurs.It is an alternative to HTTP polling.

Webhooks are a mean to extend the functionality of a service and a way to receive valuable information in near real-time, rather than continually polling a service for that data and receiving nothing valuable most of the time.

How does it work?

A web application implementing WebHooks will POST a message to a user-specified URL when certain events occur. For example, GitHub implements post-receive webhooks that allow users to integrate with a wide variety of services such as Twitter, Basecamp, or a custom script created by the user.
