Last time, in Understand How and Why REST APIs Work — Demonstrated with the VersionOne Data API, you looked at the VersionOne REST API in action, using only your browser’s address bar.
Now you’ll write code. At last.
In this article, you will
- Get familiar with the JSFiddle online editor
- Use jQuery.ajax to issue a GET HTTP request to the VersionOne Data API
The first version of the protocol had only one method, namely GET, which would request a page from a server. The response from the server was always an HTML page. — HTTP article on Wikipedia
What you’ll need

Accept: "halsjon" request header. XML is the default data format the VersionOne Data API supports.
That was easy enough. Now, let’s see how to change the data in How To Update a User Story with the VersionOne REST Data API in JSFiddle with jQuery, JSON, HTTP POST, and 20 Lines of Code.
