#  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.)
#  --------------------------------------------------------------------------------------------------------

#  It is assumed we previously obtained an OAuth2 access token.
#  This example loads the JSON access token file
#  saved by this example: Get Google Contacts OAuth2 Access Token
