Is there a quick tool (http client) that I can use to publish different data in URLs for testing purposes. Like publishing a json object, changing the headers (POST, PUT) to test the RESTful web service.
Although I have not used it this way, I am sure that http://www.fiddler2.com/fiddler2/ can do this with you using the Builder query.
There is an extended REST client plugin that you can get for Google Chrome, which I have used successfully. I find this a bit more direct and less confusing than Fiddler2.
Another really popular REST client I've seen a lot of people is Postman .
