So just looking at the method would not sufficient to tell whether the operation is idempotent or not. Looking at the method will *always* be enough to know whether it's idempotent or not. POST is not idempotent, by definition. PUT is idempotent, as is GET and DELETE, also by definition. They have their own standalone meanings, and nothing in the body of the message can change that.
