Set up Postman on Ubuntu 20.04 – Linux Hint

Developing an API from scratch can be a long process. The administration could not be less heavy and demanding. It is a comprehensive project that requires strict control and dedication and covers a wide range of life cycle processes. Fortunately, we have a factor that makes us better.

Postman is a tool for creating an Application Programming Interface (API) and automating its testing, publishing and management. From its humble beginnings as a browser extension, it has gradually evolved into one of the preferred platforms for collaborative API development. The postman is compatible with almost all commercial operating systems and with Linux.

This guide shows you how to install Postman on Ubuntu 20.04 and how to work with Postman.

The best thing about snap packages is that they have a low maintenance cost because they are automatically updated and maintained.

The official Snap-in Factor package is available directly from the developers. To request and install the snap package for the postman, start the terminal and enter the command below:

The sudo-snap installation factor

The download and installation are checked against the output data.

You can also use the factor in your web browser as an extension.

At the first start a window appears in which the login details of the user are retrieved. Since you have just installed the application, you can create an account or skip the sign-up process and try it out. However, we recommend that you create an account because you will bypass the synchronization and backup options that require you to log in with your account.

Set the request type to GET and then press the Send button. You must receive a JSON file with user lists.
