VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' It is assumed we previously obtained an OAuth2 access token.
' This example loads the JSON access token file 
' originally obtained by this example: Get Google People API OAuth2 Access Token
' or refreshed by this example: Refresh Google People API OAuth2 Access Token

Dim jsonToken As New Chilkat.JsonObject
success = jsonToken.LoadFile("qa_data/tokens/googlePeople.json")
If (success <> True) Then
    Debug.WriteLine("Failed to load googleContacts.json")
    Exit Sub
End If


Dim http As New Chilkat.Http

' -------------------------------------------------------------------------------------
' Make sure the access token was obtained with "profile" included in the list of scopes.
