The REST API interface is pretty straightforward, so you can recreate this with UrlFetch if you like. However this packages all the things you can do from the client in a simple library, and is has same call formats as the JavaScript version.

Where to get it

You can include the library in your project – the key is 


or get a copy here from Github



Most of the demos and libraries mentioned in these pages are available in their own GitHub repo, but for convenience, there is a consolidated repo where I’ll push all the associated code. If you’d like to contribute, please make a PR there.


Before starting

You’ll need to get a boss key. If you want to play with the tests below (or on github). You can get a boss key by visiting the API home, registering, and creating one in the Console. I also recommend you take a look at the tutorial there to get a feel for some of the concepts.


This is a series of tests that exercise the common functions available in the library.  Check the log file for which Urls the requests are turned into.
