Overriding Product Data

In order to modify the product data that is sent to Nosto, you need to create your own mini-module. Please read the basics how to extend or override data in Nosto extension

For modifying Nosto's product data you must register hook actionNostoProductLoadAfter and implement corresponding action method hookActionNostoProductLoadAfter(). Below is an example how your MyNosto class could look like.

File modules/mynosto/mynosto.php

<?php

if (!defined('_PS_VERSION_')) exit;

 * Depends on the "Personalization for PrestaShop" module by Nosto.
