Create a Web Service with Complex Object

The Rest API documentation shows how to expose your own services / methods as available methods through the API. It appears that all parameters to my methods are urlencoded correct? Is there a way for me to create a service method that will take an advanced structure as the body argument of the message? For example, if I wanted to create an alternative method that would receive an Entity or other Java structure and would be represented as full serialized JSON in the message body?

Thanks.

I somehow missed the API POST documentation in the Developer’s Manual. I found what I needed.

Thank You.
