# Unified ID 2.0

## Overview

[Unified ID 2.0](https://unifiedid.com/docs/intro) is an identifier created using user's PII like email. The new Unified ID2.0 will provide advertisers/publishers a new privacy-conscious targeting ID.

This integration allows you to enrich your existing Lytics user profiles and acquire Unified ID 2.0 for users that have an email or hashed email. Use the new imported ID to send it to various ad platforms to target users.

## Enrich Users

Enrich Lytics users to add [Unified ID 2.0](https://unifiedid.com/docs/intro) to their user profile. Use this UID to identify consumers to target with more relevant ad campaigns.

### Integration Details

*   **Implementation Type**: Server-side Integration
*   **Implementation Technique**: REST API Integration, Audience Trigger Integration
*   **Frequency**: Real-time Integration
*   **Resulting data**: User Fields, Raw Event Data

This integration utilizes the [Unified ID 2.0](https://unifiedid.com/docs/endpoints/summary-endpoints) API to obtain and import UID2.0 for Lytics users. Please refer to the documentation on [Unified ID](https://unifiedid.com/docs/intro) to learn more about it.

Each job run will proceed as follows:

1.  Creates a temporary Lytics Audience with users that have email or email hash or phone number or phone number hash configured during job creation.
2.  Sends the email or email hash to the [Unified ID](https://unifiedid.com/docs/endpoints/post-identity-map-v2) endpoint to acquire the user's UID2.0. Users are enriched every minute or when the queue reaches 1000 users.
3.  Sends user's UID2.0 data in stream uid\_enrichment so that it can be mapped as a user profile field.

Once the ID is enriched, it is refreshed every 90 days.

### Fields

The following fields are included in the default mapping of the uid\_enrichment stream:

Source Field

Lytics User Field

Description

Type

email unique id
