'  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.)
'  --------------------------------------------------------------------------------------------------------

'  This example loads the JSON access token file 
'  saved by this example: Get Google Contacts OAuth2 Access Token
