A blog for Day 3 (Part 3): Making API Requests with Postman
As a software tester, it's important to have a good understanding of the tools available for testing APIs. In addition to REST Assured, another popular tool for making API requests is Postman. In this blog, we'll cover how to use Postman for making API requests, including GET, POST, PUT, and DELETE requests.
Installing Postman: To get started with Postman, simply go to the Postman website and download the appropriate version for your operating system. Once you have installed Postman, you can start making API requests right away.
Making a GET Request: The GET request is the most basic type of API request and it is used to retrieve data from a server. To make a GET request in Postman, follow these steps:
Open Postman
Click the "New" button in the top left corner to create a new request
Select "GET" from the dropdown menu
Enter the URL for the API you want to call in the "Address" field
Click the "Send" button to make the request
- Making a POST Request: The POST request is used to send data to a server for processing. To make a POST request in Postman, follow these steps:
