Module to track order conversion at on order-confirmation hook

This repository is a needed part for getting the Google Tag Manager tracking conversions correctly in PrestaShop.

add page view transaction tracking to your shop

Adding page view tracking is super simple. Adding conversion tracking requires a data layer, which I added with this module.

IMPORTANT: For this code to fire, your payment method modules need to be calling PrestaShop after payment. E.g. here are the changes I needed to make to get this to happen with PayPal. As far as I can tell, this "problem" exists for both my module, and for the PrestaShop Google Analytics module.

Install the PrestaShop module "Data Layer Module" (instructions for installing a PrestaShop module can be found in the PrestaShop Documentation). It's a VERY basic module that any PHP coder can understand and expand on.
