# 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.
