I am using this code of consolibyte to getting sku of QuickBooks online products but there is no response?
<?php
require_once dirname(__FILE__) . '/config.php';
require_once dirname(__FILE__) . '/views/header.tpl.php';
$ItemService = new QuickBooks_IPP_Service_Term();
$items = $ItemService->query($Context, $realm, "SELECT * FROM Item WHERE id = '4' ");
foreach ($items as $item)
{
print_r($item->getSku());
}
