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

# Before sending REST API calls, the REST object needs to be

# See Xero 2-Legged OAuth1 Setup for sample code.

# Assuming the REST object's OAuth1 authenticator is setup, and the initial
# connection was made, we may now send REST HTTP requests..
