Identity Syncs

The Identity Sync pages are under construction.

What Are Identity Syncs?

Identity Syncs are part of the MetaRouter integration ecosystem, designed to unify user identities across different parts of your website or app, ensuring that each event is accurately associated with the same individual. Rather than relying solely on basic cookies or fragmented IDs, Identity Syncs apply specialized logic to maintain a consistent user identity across pages and sessions. This approach is critical for accurate analytics, personalized experiences, and more effective marketing.

Sync Injector

Identity Syncs utilize the Sync Injector, a MetaRouter component that dynamically injects user identifiers—such as hashed email addresses, custom user IDs, or vendor-specific tokens—directly into the event stream. By automatically capturing and associating these identifiers, the Sync Injector eliminates the need for multiple tracking scripts or manual ID mapping. This ensures that each event is correctly attributed to the appropriate user, reducing operational overhead and enabling more efficient data analysis.

For more details on the Sync Injector, refer to this documentation.

Integration Ecosystem

Identity Syncs can function in different ways, depending on the use case:

• With a Starter Kit – Combines identity resolution with data routing and event transformation.
• As a Standalone Solution – Unifies user IDs without additional data transformation. These IDs can work alongside other MetaRouter components to manage both event transformation and identity enrichment.

This flexibility allows Identity Syncs to support various data strategies while ensuring accurate and consistent user identification.
