Communication is a vital concept that breeds understanding between any two entities, whether humans, machines, or applications. There needs to be a standard way that allows for information sharing between the two parties.

That's probably why language was developed in human society to meet the need for giving and receiving information.

Besides humans, there is also the need for applications to share vital data with each other. That's why different protocols (language used for communicating over computer networks) were developed.

One such mode of sharing data is called Webhook and we will be profiling it in this guide. As usual, we will be kicking off with an overview of webhook for those who are new to the concept.

This tutorial is a simplified answer to a member's question on "What a webhook is and how to set it up" under the training titled "Guide to Promoting Your ClickBank Products Using ClickFunnels".

About Webhooks

Webhooks enable the seamless transfer of real-time data from one web application to the other. Like API (application programming interface), webhooks are one of the ways apps communicate with each other. However, both API and webhooks differ in the way they share information as you will find out later on.

Interests in webhooks have been on the steady increase within the past few years as shown by Google Trends. Communications via webhook are always triggered by the occurrence of clearly-defined events.

For instance, your company has an e-learning platform that offers online courses to marketers. And you want to offer personalized messages each time a student logs into your school.

The use of webhooks will enable you to receive data about each student from an app that has the data. The event in this case is a student logging into the online learning platform. A webhook will not do anything by itself until a particular event occurs before it is triggered.
