Postman, a free Chrome browser app plugin is a great tool for working with REST web services APIs. We are often creating REST APIs for clients, or integrating a 3rd party REST APIs into clients’ web applications or mobile apps and often need to troubleshoot our code or demonstrate an API that we’ve built to a client. The Postman REST client is a tool that enables users to post and get data as well as perform a wealth of other HTTP commands from your Chrome borwser. It will enable you to test your APIs by posting in paramters and getting results back in JSON or XML format.
We highly recommend giving this free tool a try as it can save you time and frustration while developing and working with REST APIs.
