Contrary to Parasoft, neither Swagger nor POSTMAN require us to create a framework in order to retrieve the response from the service. To make sure that the service is up and running along with the build version of an API that is being deployed into the area, developers and automation engineers typically use POSTMAN. Application Programming Interface, or API, is the abbreviation. The methods for scripts or programmes to communicate with an application or service are defined by an API, or application programming interface. They function by transferring data and information between different systems, applications, and gadgets. We mentioned below are the steps to use Postman to Execute APIs.

Steps to use Postman to Execute APIs

Step 1: Launch Postman by clicking on the logo. After it completely loads the main screen follow this steps to create your collection of requests: Step 2: On the “collections” tab click on the “+” button to create a new collection. A new collection will appear and you will be able to edit its name, description, and many other settings. Step 3: Then right click on that new collection and select “add request” to create your first request. Step 4: Select the recently created request and enter the API endpoint where it says ‘Enter request URL’ and select the method (the action type) on the left of that field. The default method is GET but we will use POST in the example below. Step 5: Add authorization tokens/credentials according to the server-side requirements. The different methods/protocols Postman supports are: Step 6: Enter headers in case they are required. Step 7: Enter a POST body in case it is required. Step 8: If you wish to execute this API now, hit the ‘Send’ button, which is located to the right of the API request field. You can also click on the ‘Save’ button beside it to save that API request to your library.

Final Words

We hope you like our article on how to use Postman to Test API. Scalable API testing software like Postman integrates easily into CI/CD pipelines. Abhinav Asthana started it in 2012 as a side project to streamline the testing and development process for APIs. Application Programming Interface, or API, enables interoperability between software programmes by facilitating API calls. In this Postman API testing lesson, we will use the REST API, which is now the most popular API. Representational State Transfer, also known as REST, is another abbreviation.
