' 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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set jsonToken = Server.CreateObject("Chilkat.JsonObject")
success = jsonToken.LoadFile("qa_data/tokens/googleContacts.json")
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( "Failed to load googleContacts.json") & "</pre>"
    Response.End
End If

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.AuthGoogle")
set gAuth = Server.CreateObject("Chilkat.AuthGoogle")
gAuth.AccessToken = jsonToken.StringOf("access_token")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Rest")
set rest = Server.CreateObject("Chilkat.Rest")

' Connect using TLS.
bAutoReconnect = 1
success = rest.Connect("www.google.com",443,1,bAutoReconnect)

' Provide the authentication credentials (i.e. the access token)
success = 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
