Installing Postman

When exploring and testing a web API, it is invaluable to have an interactive environment that allows you to fine-tune requests. For example, you may need to configure the HTTP method, headers, or body of the request – all of which the browser does not allow you to do. Instead of testing in a browser, we can use tools made specifically for interacting with APIs. One of the most popular API tools in the industry is Postman. Postman is a cross-platform tool that puts you in full control of configuring and executing API requests.

Installing Postman is easy thanks to its cross-platform nature. You can download the installer on their downloads page .

  1. After installation, you can open the app. Postman will first prompt you to make an account, but if you are uncomfortable doing so, at the bottom of the screen is the option to sign up for an account later.

The main view of Postman is the launchpad view.
