In today’s digital world, APIs (Application Programming Interfaces) are the backbone of modern web and mobile applications. They enable communication between different software systems which helps in seamless sharing of data . As APIs continue to grow in complexity and importance, so does the need for efficient tools to test, manage, and collaborate on API development. This is where Postman comes into play.
Postman is a collaborative platform that is mainly used for API development. It has simplified building, testing, and managing APIs by providing a user-friendly interface. In the very beginning, it started as a Chrome extension, but later it developed into a fully fledged app used by millions of testers and developers across the globe.It helps in streamlining the API lifecycle from design to deployment.With features like Collections, Environment Variables, Test Scripts, and Mock Servers, Postman helps teams collaborate efficiently and build reliable APIs faster. Whether you’re making simple GET requests or complex POST operations with headers, tokens, and body data, Postman provides an intuitive interface to handle it all.

STEP 5:
Click Next, then provide a meaningful name for your workspace and click on Collections in the left sidebar.Click + New Collection
Give your collection a relevant name
Step 6 :
Now, add the HTTP requests you want to work with.
STEP 7:
Now, to begin testing with a real API, follow these steps:
Go to the following website:
https://jsonplaceholder.typicode.com
From the list of sample endpoints, copy the following example API URL:
https://jsonplaceholder.typicode.com/posts/1
This GET request retrieves a sample blog post in JSON format.
STEP 8:
Add the following JSON to the get request and click on the save option, and click on send
Finally, you are done with your first successful API call.

Whether you’re facing an issue, exploring a new feature, or looking for best practices, the Postman community is always ready to help and inspire.
Statistics on Usage of Postman
Postman has become one of the most powerful and widely used tools in the world of API development, testing, and team collaboration. Its journey began in 2012, when it was created by Abhinav Asthana, along with his co-founders Ankit Sobti and Abhijit Kane. Initially, it started as a simple Chrome browser extension meant to make the process of sending HTTP requests easier for developers. At the time, working with APIs required technical knowledge and command-line tools, which were not always beginner-friendly. Postman changed that by offering a clean, graphical interface that simplified the process of making API calls, viewing responses, and debugging errors—all within a few clicks.
What started as a lightweight utility soon gained massive popularity among developers because of its simplicity and usefulness. Postman allowed developers to test APIs quickly without writing code, saving both time and effort. As demand grew, the team behind Postman began adding more advanced features and support for the full API lifecycle. Over the years, Postman transformed from just a request builder into a comprehensive platform for API design, testing, automation, monitoring, documentation, and team collaboration. This gradual but strategic evolution played a crucial role in attracting a massive user base from all around the world.
As of 2024, Postman has reached a significant milestone—it now serves over 35 million users worldwide. This number includes not just software developers but also testers, QA engineers, DevOps teams, product managers, and even business analysts. Compared to its user base of 25 million just a year ago, this growth of 10 million new users in a short span is a strong sign of the increasing importance of APIs in software projects and the trust users have in Postman as their go-to platform. APIs (Application Programming Interfaces) have become the building blocks of modern applications, helping different software systems communicate with each other. Whether it’s a mobile app connecting to a cloud service or a website pulling data from a database, APIs are at the core of it all. With the rise of microservices architecture, cloud-native development, and third-party integrations, the need for reliable API tools like Postman has never been greater.
