Postman Interface Overview

? Postman Interface Overview

? Quick Overview

Postman is a popular API development and testing tool. Its interface is designed to help developers create, send, organize, and test API requests efficiently using a clean and modular layout.

? Key Concepts

  • Workspace – Central area where API work is organized
  • Sidebar – Navigation panel for collections and history
  • Request Builder – Main area to configure and send requests

? Syntax / Theory

The Postman interface is divided into logical sections to streamline API workflows:

  • Top bar manages workspaces and environments
  • Left sidebar organizes collections and request history
  • Center panel is the request builder

? Code Example(s)

// Example of an HTTP GET request used in Postman
