Demonstrates how to update a Google Contact. Perl

# 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
