What is Postman?

Postman is a powerful API development and testing tool for developers and testers. It allows you to make HTTP requests, test API endpoints, and manage API collections and environments. With Postman, you can easily create, save, and share API requests, and view response data in a variety of formats, including JSON, XML, and HTML.

It also provides features such as request history, environment variables, data persistence, and collaboration tools. Postman is available as a native app for Mac, Windows, and Linux, and as a browser extension for Chrome.
