# 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..

# Build a Google Calendar event:

json.put_EmitCompact(false)
json.UpdateString("kind","calendar#event")
json.UpdateString("summary","Eat Lou Malnati's Pizza")
