This is a quick tutorial to make you install and run Postman.
Postman was popular with its extension for Google Chrome. So the first thing you probably did is navigating to Google Chrome Webstore and downloading Postman extension.
Then to access the Postman extension, type on the following URL on Google Chrome:
You should see an icon for Postman now:
A window loads for seconds then displays the following message:
This Chrome App is being deprecated.
You can ignore the message and continue to the next menus. The Postman dashboard will load nomally. But I recommend to use the Postman native App instead because it will be the future of Postman development, which takes us to the next paragraph.
If you installed both Chrome Postman extension and Postman native app, then they will both appear on your computer. Click on this icon:
Postman native app
Go to Postman webpage and download the version that fits yout computer OS. Run the normal installation steps. It takes a little time if your computer is as slow as mine :). Click on “skip signing in and take me to the app”.
The first thing you encounter in the Postman menu is the Launch window. There you find frequent tasks.
The most important blocks are Environments, Requests and Collections.
Here you define the environment variables. Just like a programming languange, you set a variable Host1 for example as “220.127.116.11”. So instead of typing each time the IP address you type only Host1.
A single unit of Postman instruction is called Request. Consider a Request in Postman almost like a function in Python or C, but without a return value.
You can group your Postman Requests in a Collection.
