Отображать электронные письма — Google Contact API

Я создаю все необходимое, чтобы получить электронную почту для контакта Google. Смотри мое видео http://screencast.com/t/3j3elQtu

Я не могу найти, где я сделал ошибку. Я прошёл авторизацию и получил ответ, но в этом ответе я не могу найти ни одного адреса электронной почты моих контактов

// other settings
$client->setClientId($CLIENT_ID);

}

// create service and get data
$req = new Google_Http_Request('https://www.google.com/m8/feeds/contacts/default/full?v=3.0');

$val = $client->getAuth()->authenticatedRequest($req);

$response = json_encode(simplexml_load_string($val->getResponseBody()));
print "<pre>" . print_r(json_decode($response, true), true) . "</pre>";

echo '--------------------------------------------------------------------';

echo '<pre>';
var_dump($val);
echo '</pre>';

После отправки запроса я получаю следующий ответ:
