Postman

Postman is an all-in-one platform for working with APIs throughout their entire lifecycle. It provides tools to send API requests, view responses, write tests, create documentation, and monitor performance. Unlike basic HTTP clients, Postman offers a complete environment where teams can organize their work into collections, share them with teammates, and automate testing.

The platform includes an easy-to-use interface where you can build requests without writing code, though it also supports advanced scripting when needed. Postman works as a desktop app, web app, or through command-line tools for automation. It integrates with popular development tools and supports team collaboration through workspaces, making it ideal for both individual developers and large organizations building complex API systems.

Getting started with Postman is straightforward. Here are the key steps:

• Download the desktop app or use the web version, then create a free account to access all basic features.

• Create your first request by entering an API URL, selecting the HTTP method like GET or POST, and adding any needed headers or body data.

• Organize related requests into collections to keep your work tidy and reusable across projects.

• Use environments to store variables like API keys or base URLs, making it easy to switch between development and production settings.

• Write tests using JavaScript to automatically verify API responses and catch issues early in development.

• Share collections with your team through workspaces, allowing everyone to collaborate and stay updated on API changes.

• Use the built-in documentation feature to automatically generate clear guides for your APIs that update as you make changes.
