Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIs—faster

API testing is a type of software testing that analyzes an application program interface (API) to verify it fulfills its expected functionality, security, performance and reliability. The tests are performed either directly on the API or as part of integration testing

API Testing has gained popularity these days because of evolution of Micro Services. Each components are made as web service and to test these web services we can make use of Postman to test RESTful APIs manually.
