The “thing” retrieval pattern

use GET and not POST

Why not POST?
–Overloaded POST: the not-so-RESTful pattern

–It’s overloaded because a single HTTP method is being used to signify any number of non-HTTP methods.

–By using POST it will happen very easy that we implement an RPC service. In a RPC service we are using post and the Action is one of it’s parameters: ”/orders?action=delete&id=13” That’s not REST!

it's as easy as that
