First: up-vote @codexer 's answer.

Second, use the following function in his code to decode the base64URL encoded body. Google not only base64 encoded the body, it is also URL encoded :-/

/// 

    /// Turn a URL encoded base64 encoded string into readable UTF-8 string.
    /// 
    /// base64 URL ENCODED string.
    /// UTF-8 formatted string
    private string DecodeURLEncodedBase64EncodedString(string sInput)
    {
        string sBase46codedBody = sInput.Replace("-", "+").Replace("_", "/").Replace("=", String.Empty);  //get rid of URL encoding, and pull any current padding off.
        string sPaddedBase46codedBody = sBase46codedBody.PadRight(sBase46codedBody.Length + (4 - sBase46codedBody.Length % 4) % 4, '=');  //re-pad the string so it is correct length.
        byte[] data = Convert.FromBase64String(sPaddedBase46codedBody);
        return Encoding.UTF8.GetString(data);
    }
