Как использовать API VK в Yii2?

public $enableCsrfValidation = false;

	public function actions()
	{
		return [
			'social' => [
				'class' => 'yii\authclient\AuthAction',
				'successCallback' => [$this, 'successCallback'],
			],
		];
	}

/**
	 * @param $client
	 */
	public function successCallback($client)
	{
        $day = 86400;
		$client_id = Yii::$app->request->get('authclient');
		$attributes = $client->getUserAttributes();

        // VK
		if($client instanceof VKontakte)
		{
			$auth_params = $client->getAccessToken()->getParams();
			$email = ArrayHelper::getValue($auth_params,'email','');
            // Аватарка из VK да ПОБОЛЬШЕ!!!
            $vk_data_response = $client->api('users.get','POST',['uids'=>  $attributes['id'] , 'fields'=> 'photo_max_orig']);
            if($vk_data_response = ArrayHelper::getValue($vk_data_response,'response',false))
            {
                $vk_data = array_shift($vk_data_response);
                Yii::$app->session->setFlash('social_avatar', $vk_data['photo_max_orig']);
            }
		}

//...
