The point is that your RESTful API is not RESTful at all. It's just RPC using JSON. REST is an architectural style that models the interaction around data and hypertext instead of actions.

A good rule of thumb is: if the documentation mentions "methods" as anything other than the uniform ones (if you're using HTTP, that would be GET, POST, etc), then it's RPC, not REST.

Note: I'm not saying your API is bad; RPC is a completely valid model. I'm just saying it's not RESTful.

That's true, we don't use HTTP methods (PUT, GET, POST, DELETE, etc) as part of the API. In fact we treat POST/GET the same for ease of use.

EDIT: to be fair, in the docs we never say it's a RESTFul API, it was MY mistake in my first comment.
