Google AdSense API ничего не показывает

Я разрабатываю Google AdSense Management API в php, я новичок в этом.

Я ничего не получаю после входа в систему,

Я пытаюсь бежать пример образец кода.
но я получаю этот экран после входа в мою учетную запись!

мой adsense-sample.php код является:

<?php

require_once 'templates/base.php';
session_start();

Что-то, чего мне не хватает, чтобы добавить в этот код? Пожалуйста помоги.

Кроме того, я не могу точно понять, какой путь я должен указать на

Измените этот путь, чтобы указать на ваш
установка клиентской библиотеки!

в приведенном выше коде. (Это правильно, что я поставил в настоящее время?)
