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

' Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
' Once connected, the REST object may be re-used for many REST API calls.
' (It's a good idea to put the connection setup code in a separate function/subroutine.)
