PrestaShop

• To integrate CartStack on your PrestaShop site, you will need to update your header.tpl file. This file is located in your PrestaShop themes folder ie.  /themes/your-theme-name/header.tpl
• Place the CartStack code snippet (from the code page of your CartStack account) right above the </head> tag.
•  You will need to wrap the tracking code in opening and closing {literal} tags for PrestaShop to process it correctly.

Example:

{literal} 
  <script data-siteid="XXXXXX" src="https://api.cartstack.com/js/customer-tracking/www.website.com_XXXXXX.js" type="text/javascript"></script> 
{/literal}
