WEBHOOKS

Webhooks are ways for a web application and external service to send real-time notification to one or more applications. They are automated HTTP requests, triggered when specific events such as comments being posted to a blog, occurs in a source system and sent to a destination system, sometimes with a payload of data.

The concept of webhooks consists of two parties:

The sender:- The application that is notifying another system about an event. It gathers important data about the event and packages it in a payload, then initiates an HTTP POST request containing the payload data to the webhook URL or endpoint already provided by the receiver.
The receiver:- The application that receives and processes the webhook data. It receives the HTTP request and extracts and processes the payload data.

THINGS TO NOTE ABOUT WEBHOOKS
