# This example will send an HTTP POST with the body of the HTTP request containing JSON.

# Create the following JSON: { "name": "Harry", "state": "FL" }

# Send the POST
# You can send the POST to the URL below.  
# The response will contain the raw body of the request that was sent.
# (i.e. everything except the HTTP request header).
