Does Lytics surface a canonical - or at least unique - user ID within the platform or its integrations?

Lytics offers a field called "Lytics ID" stored on the profile as "_id." The Lytics ID plays a crucial role as an attribute, acting as a unique identifier for each profile within the Lytics platform.

It's important to note that the Lytics ID is derived by anonymizing the profile's primary key/value string. This ensures that the Lytics ID remains consistent and unique, with the primary key representing the highest-ranked identifier present on the profile.

When it comes to merging profiles, Lytics employs a specific mechanism to determine the Lytics ID for the merged profile. In such cases, the highest-ranking profile ID is selected as the primary identifier once the merge operator delineates how the fields should be mapped and consolidated.

The Lytics ID can be utilized for downstream operations and exported for various purposes. It is a reliable means to identify and distinguish individual users within the Lytics ecosystem and its integrations.
