How does a Programmer know what to Post?

No good answer.

The programmer just has to read the text documentation.
This is indeed simpler and faster than WSDL/SOAP for simple services. But it is then just another kind of RPC.
REST does not fit our definition of web service.
There is no machine-readable description including at least the inputs and outputs for the service.
