# 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

# Connect using TLS.
$bAutoReconnect = $true

# Provide the authentication credentials (i.e. the access token)
$rest.SetAuthGoogle($gAuth)

# ----------------------------------------------
# OK, the REST connection setup is completed..
# ----------------------------------------------

# To retrieve the contact, send the following:

# 	GET /m8/feeds/contacts/default/full/{contactId}
# 	GData-Version: 3.0

$rest.AddHeader("GData-Version","3.0")
