![]() ![]() Using the tool simplifies API workflows in testing and. It helps developers design, build, test and improve their APIs with more iterations. Postman is a GUI-based API testing platform with more than 20 million users around the world. Then, I get the response data in easy-to-read JSON with a status code of 200, confirming the GET request was successful. Most network engineers have heard about cURL and Postman in various networking and developer communities. All I have to do is plug the route into the address bar, select the GET response method on the dropdown box to its left, punch in my API key in the “ Headers” section, specify that I want the response in “ pretty” JSON format, and hit send. With Postman, such a test is much more streamlined. Granted, I would probably need to write all this out any way to make a functioning app using this API, but doing all this to simply test an API's functionality is unnecessarily tedious and time-consuming when something like Postman exists. If I wanted to test a GET request against this route without using Postman-instead actually writing out code in something like Flask-I would have to write out a whole new route and function to perform the request, then I would have to specify with more code what I want the response to look like, and finally, I would have to print out the response to the console or provide some other way of actually viewing the response. Let’s say I wanted to make a GET request against a fan-made API for the video game Hearthstone to search for cards with “ Archer” in their name. Update the access key as indicated by the TODO comment. Add the following code to the end of the pre-request script. It offers a sleek user interface with which to make HTML requests, without the hassle of writing a bunch of code just to test an API's functionality. Here's how to configure Postman for testing the REST API, generating the authentication headers automatically: Add the signRequest function from the JavaScript authentication sample to the pre-request script for the request. Postman is a great tool when trying to dissect RESTful APIs made by others or test ones you have made yourself. ![]()
