PHP: Call to undefined method in Google Play Developer API - php

Question

I'm going to get list of my in-app products from using google API, by its PHP client from a remote server.
Here is my code:
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("https://www.googleapis.com/auth/androidpublisher");
$service = new Google_Service_AndroidPublisher($client);
$optParams = array('token' => 'my token....');
$results = $service->inappproducts->list ('my.package.name', $optParams);
When I run this code I get the following error:
Fatal error: Call to undefined method Google_Service_AndroidPublisher_Inappproducts_Resource::list()
I implemented my code based on some samples and details listed in api reference. I just brought var_dump of $service->inappproducts for your reference:

I'm shooting from the hip here, but try this:
$results = $service->inappproducts->listInappproducts('my.package.name', $optParams);
Instead of:
$results = $service->inappproducts->list ('my.package.name', $optParams);
And as I commented, you should change your client secret, since it looks like you posted in your var_dump there.
