                                        client_secret=CLIENT_SECRET)

    # Setup a Redirect URI
    auth_url = authenticator.authorization_url(redirect_uri=REDIRECT_URI)

    # Open the authorization URL and capture the code from the URL
    webbrowser.open(auth_url)
    code = raw_input("Enter the code param from the URL: ")

    # Exchange the code for an access token
