Install Postman

The snappy packaging technique is the simplest way to install Postman on Ubuntu 20.04. Snaps are self-contained software packages that include the binary as well as all of the application's dependencies. Snap packages can be installed using the Ubuntu Software program or the command line.

The developers of Postman distribute and maintain the Postman snap package.

Open your terminal (Ctrl+Alt+T) and enter the following command as a user with sudo rights to install the Postman snap:

sudo snap install postman

Depending on the speed of your internet connection, the download may take some time. If the operation is successful, the following output is displayed:

Upgrades are simple and secure with Snap packaging. The Postman package will be automatically updated in the background whenever a new version is released.

Alternatively, you can use the Ubuntu Software Center to install Postman. Simply type in Postman and hit the install button.

Using Postman

To launch the program, put "Postman" into the Activities search box and click the icon.

When you first launch Postman, a box similar to this will display, prompting you to log in or create a new account:

You may organize your work in Workspaces, generate backups, and sync your data across various devices after creating an account. Click "Skip signing in and direct me straight to the app" if you don't want to log in.

We'll perform a simple Get call to an online REST API and get a JSON response with a list of users to demonstrate how Postman works.

Open a new tab, type https://jsonplaceholder.typicode.com/users into the address bar, select GET as the request type, and hit the SEND button. If the request is successful, a JSON object containing an array of users will be returned.
