Postman is a popular API testing tool that is used to simplify the process of developing and testing APIs (Application Programming Interface). API acts as a bridge between two software applications which enables them to communicate and share data. In this article, you will learn how to generate API documentation using Postman.

Prerequisites

  • Understanding of APIs and HTTP Requests.
  • Installation of Postman.
  • Knowledge of API Development.

Steps to Generate API Documentation

Step 1: Download and Open the Postman

Step 2: Create a Collection

Click on the collection tab and then click on the plus sign or create collection button. Then give it a name in this case we are naming it GeeksforGeeks.
