Finally, Proper Google Analytics 4 for OpenCart 4

OpenCart 4 ships without any built-in Google Analytics integration.
No GA4 tracking. No ecommerce events. No revenue attribution.

This extension fixes that — in minutes.


Complete GA4 Ecommerce Tracking for OpenCart 4

Turn your OpenCart store into a fully tracked GA4 ecommerce setup without touching code, editing themes, or fighting with Google Tag Manager.

Simply install the extension, enter your GA4 Measurement ID, and your store starts sending accurate ecommerce data directly to Google Analytics 4.
