The Postman tool allows you to organize your API requests into collections and folders that share common values across requests with environment variables, script tests with the built-in node.js based runtime, and automate them with Newman. But deep down, Postman is built on an extensive set of powerful tools that are very easy to use. At first glance, it looks like an interface for sending HTTP requests and viewing responses. The Postman tool does more than just testing APIs. That's why following some API design guidance since the beginning of your API's development is key to minimize problems.

As the prime motive of creating an API is to enable other applications to use the services, every stage of the API development process requires testing for functionality, exception handling, and security. The REST framework sets a set of guidelines that should be followed while creating an API. So, stay tuned.Īlthough there are a number of ways in which an API can be created, a Web API is usually created by using the REST (Representational State Transfer) framework. The Postman tool has taken the API world by storm since its inception and is used by over 7 million developers over the world every month! We will be talking more about the Postman tool, testing APIs with Postman, testing automation, and more in this article. And that’s when the Postman tool was introduced. We are surrounded by APIs and it is only creating a better world.Īlthough APIs are making our lives easier, developers have their share of hurdles in terms of testing them before using it on real-time data. From being able to log in to your Google or social media accounts from any website to being able to choose your favorite payment service in your eCommerce store. Right from booking a flight ticket to checking the weather report. As an end user, we use APIs everyday without even realizing it. Today, APIs (Application Programming Interfaces) are all over the internet and it plays a significant role in our economy.
