HTTP client to help test web services easily and efficiently

While i was dealing with Apps which is connect to serve the main issue i faced was checking the response. What i used at staring was debugging the app each time. In the case of json parsing I waste a lot of time only for checking the responses.
Then i got a solution Postman - REST Client.

It is very simple. You can POST or GET data to the server using postman.
