Installing postman

There are two ways you can go about installing postman:

Using Snap
Downloading the Postman Desktop app

1. Using Snap

Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel.

Snaps are cross-distribution, dependency-free, and easy to install applications packaged with all their dependencies to run on all major Linux distributions. From a single build, a snap (application) will run on all supported Linux distributions on desktop, in the cloud, and IoT. Supported distributions include Ubuntu, Debian, Fedora, Arch Linux, Manjaro, and CentOS/RHEL.

Check mode about the snaps in their site here.

First ensure snapd (package providing support for snap) is installed:

sudo dnf install snapd

Then create a symbolic link to /var/lib/snapd/snap for /snap:

sudo ln -s /var/lib/snapd/snap /snap

Then install Postman:

sudo snap install postman

2. Downloading the Postman Desktop app

Head over to the Downloads page here and click on the Download the App button:

Once downloaded, open your terminal and move to the downloads directory:

$ cd ~/Downloads/

Check that the Postman file is downloaded:

$ ls
Postman-linux-x86_64-8.11.1.tar.gz

Now extract the file:

$ tar -xzvf Postman-linux-x86_64-8.11.1.tar.gz

Now move the extracted directory to the /opt directory:

$ sudo mv Postman /opt

Create a symlink for the executable /opt/Postman/Postman called /usr/local/bin/postman to access the Postman command:

$ sudo ln -s /opt/Postman/Postman /usr/local/bin/postman

To test that its working as expected, type postman in terminal:

$ postman

If all goes well, you should see Postman launch, the first page is the login page, skip that and you will see this:

Adding a Postman Launcher

A more convenient way to launch Postman is to use the launcher.

To start the app from a launcher icon, you need to create a .desktop file in the system launcher location in this path /usr/share/applications/. The .desktop is
a shortcut that is used to launch an application in Linux. f

For Postman desktop app lets create the file with this command:

sudo vim /usr/share/applications/postman.desktop

Then let’s add the following content pointing to our Postman binary:

[Desktop Entry]
Type=Application
Name=Postman REST Client
Icon=/opt/Postman/app/resources/app/assets/icon.png
Exec="/opt/Postman/Postman"
Comment=Postman REST Client Desktop App
Categories=Development;Code;Testing;

Save the file and close it.

You should now be able to access Postman by searching in the application launcher.

Removing/Uninstalling Postman Rest Client

If for some reason you no longer want Postman in your machine, you can remove it.

If it was installed using snap, use this command to. uninstall:

sudo snap remove postman

If you installed it using the manual method, you can remove it by running the following commands:

Remove the Postman Installation in /opt/Postman and the symbolic link:

sudo rm -rf /opt/Postman && rm /usr/local/bin/postman

Remove the Launcher:

sudo rm /usr/share/applications/postman.desktop

That is all. You are now able to install Postman in your system and uninstall it if need be.
