# Activity 24: POSTMAN

## FIRST WHAT IS POSTAMAN?

Postman is an [API platform](https://www.postman.com/api-platform/) for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIs—faster. Easily store, catalog, and collaborate around all your API artifacts on one central platform. The Postman platform includes a comprehensive set of tools that help accelerate the API lifecycle—from design, testing, documentation, and mocking to the sharing and discoverability of your APIs.
