SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables cross-device tracking for authenticated users and defines user properties to persist across events in GA4, giving a unified view of user journeys.

Core Features & Use Cases

User ID implementation: Set a persistent user_id across devices to stitch sessions.
User Properties: Define and publish user properties to enrich analytics with custom attributes.
Reporting Identity: Configure identity options to balance privacy and completeness (Blended, Observed, Device-based).
Cross-Domain Tracking: Extend user identity across domains for seamless journeys.
Use Case: Track a logged-in user across mobile and desktop to reveal a single journey.

Quick Start

Push the authenticated user_id to the dataLayer on login and map it to GA4 via a User ID parameter in the GA4 configuration. Example: dataLayer.push({ user_id: 'USER_12345' }).
