GSC_Client and oAuth2 access

I am starting work on a PHP script that will run as a cron job and periodically update product lists through the Google Shopping API.

I downloaded the GSC client library for PHP and am trying to work through the Google Shopping API to access the token. However, it seems that somewhere in the docs some kind of step has gone missing regarding how to actually request a token after creating the URL.

Here is my code:

require ("./lib/shoppingclient/GShoppingContent.php");

const G_MERCHANT_ID     = '**********';
const G_CLIENT_ID       = '**********';
const G_CLIENT_SECRET   = '**********';

$obj_client = new GSC_Client (G_MERCHANT_ID);

// Obtain an OAuth2 token to access the API with
$obj_token  = new GSC_OAuth2Token (G_CLIENT_ID, G_CLIENT_SECRET, USER_AGENT);

$str_url    = $obj_token -> generateAuthorizeUrl ('urn:ietf:wg:oauth:2.0:oob');
echo ($str_url . PHP_EOL);

/* @var $obj_response _GSC_Response */
$obj_response = $obj_token -> makeAuthenticatedRequest (curl_init ($str_url));
echo ($obj_response);

When I run the above from the command line, I get:

https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=blah-blah-blah-etc-etc-etc ...
