What are Webhooks?

A webhook is a way for a web application to send a message to another application when an event occurs. For example, when a user creates a new account on a website, the web application can send a webhook to another application to notify it of the new user.

How do Webhooks Work?

Webhooks work by setting up a URL endpoint on the receiving application. This endpoint is an API endpoint that is designed to receive the message sent by the sending application.

When an event occurs on the sending application, it sends an HTTP POST request to the URL endpoint of the receiving application. The message contains all the relevant data about the event.

The receiving application then processes the message and performs any necessary actions based on the data provided in the message.

For example, if the sending application sends a webhook to notify the receiving application that a new user has created an account, the receiving application can create a new user record in its database.

Benefits of Webhooks

Webhooks have several benefits:

  • Real-time communication: Webhooks enable real-time communication between web applications. This means that when an event occurs, the receiving application is notified immediately, rather than having to wait for a scheduled sync or batch process.
  • Reduced load on servers: Webhooks reduce the load on servers by eliminating the need for polling or scheduled syncs. With webhooks, the sending application only sends a message when an event occurs, rather than constantly polling the receiving application.
  • Customizable integration: Webhooks allow for customizable integration between web applications. The sending application can choose which events to send webhooks for and the receiving application can choose how to handle those events.

Webhooks are a powerful way for web applications to communicate with each other in real-time. By setting up a URL endpoint on the receiving application, webhooks enable real-time communication, reduce the load on servers, and allow for customizable integration between web applications.
