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

# This example uses a previously obtained access token having permission for the 
# Google Calendar scope.

# In this example, Get Google Calendar OAuth2 Access Token, the access
# token was saved to a JSON file.  This example fetches the access token from the file..
