Как получить весь профиль пользователя (linkedin api)

Вот мой текущий запрос API:

https://api.linkedin.com/v1/people/~:(firstName,lastName)

Однако это возвращает только имя и фамилию.

Мой объем:

r_fullprofile r_contactinfo r_emailaddress

Как получить весь профиль пользователя?

Вот мой текущий код:

        <?php
        // Change these
        define('API_KEY',      'xxx'                                          );
        define('API_SECRET',   'xxx'                                       );
        define('REDIRECT_URI', 'xxx');
        define('SCOPE',        'r_fullprofile r_contactinfo r_emailaddress');

        // You'll probably use a database
        session_name('linkedin');
        session_start();

        // OAuth 2 Control Flow
        if (isset($_GET['error'])) {
            // LinkedIn returned an error
            print $_GET['error'] . ': ' . $_GET['error_description'];
            exit;
        } elseif (isset($_GET['code'])) {
            // User authorized your application
            if ($_SESSION['state'] == $_GET['state']) {
                // Get token so you can make API calls
                getAccessToken();
            } else {
                // CSRF attack? Or did you mix up your states?
                exit;
            }
        } else {
