Google Tag Manager with GA4

This module integrates Google Tag Manager (GTM) and Google Analytics 4 (GA4) into a PrestaShop store through a single, unified setup. Rather than loading separate tracking scripts, it configures GA4 automatically inside the GTM dataLayer, so both tools work together without conflicts or redundant page-load overhead. No coding is required — the entire setup is handled through the module's admin configuration panel.

• Dual GTM + GA4 integration: When both a GTM Container ID and a GA4 Measurement ID are provided, GA4 is automatically pre-configured within the GTM container, enabling advanced analytics alongside full tag management flexibility.
• Zero-code setup: Enter your GTM and GA4 IDs in the back office and save — the module handles script injection in both the page header and the body noscript fallback following Google's recommended implementation pattern.
• Enhanced measurement features: With GA4 enabled, the module activates tracking for page views, scroll depth, outbound link clicks, file downloads, internal site search, and video engagement events.
• GTM-only mode: If only a GTM Container ID is provided, the module loads the GTM container normally without GA4, leaving tag configuration to be done manually within GTM.

This module is suited for store owners and marketers who want a clean, performance-conscious analytics implementation without writing custom code. It is equally useful for developers who want a correctly structured GTM dataLayer as a foundation for additional custom tags.
