POSTMAN Introduction<\/h2>\n\n\n\n

POSTMAN is an API client used to develop, test, share and document APIs. It is used for backend testing where we enter the end-point URL, it sends the request to the server and receives the response back from the server. The same thing can be accomplished through API Templates like Swagger as well. In both Swagger and POSTMAN, we do not have to build a framework (unlike Parasoft) to fetch the response from the service.<\/p>\n\n\n\n

This is the main reason for which POSTMAN is used frequently by the developers and automation engineers to ensure that the service is up and running along with the build version of an API that is being deployed into the region.<\/p>\n\n\n\n

It essentially helps in hitting API endpoints by quickly creating requests as per the API specification and dissecting the various response parameters like the status code, headers, and the actual response body itself.<\/p>\n\n\n\n
