;  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
