Re: IWS and input parameters...

There  are articles part 1-3[1] that will help you.  The convention is for 
POST  to create  a resource, POST  to update a resource, GET to retrieve, 
and  DELETE to delete. 

But you can do anything you want. 

If you want to use GET, you  would have   to pass  the data  as query 
string.
