#  Note: Requires Chilkat v9.5.0.64 or greater.

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

set rest [new_CkRest]

#  Before sending REST API calls, the REST object needs to be
#  initialized for OAuth1.
#  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..
