// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Create the JSON that is to be the body of the HTTP request.
// The JSON created by this code is shown at the bottom of this example.
// 
// The JSON Code Generator at http://tools.chilkat.io/ can be used
// to generate the following code from sample JSON.
