Client-Side UID2 Integration with Prebid.js

Configuration: Prebid's UID2 module is configured with your public credentials (subscription ID and server public key)
Token Management: Prebid generates, stores, and automatically refreshes UID2 tokens in the background when expired
Local Storage: Prebid stores tokens in localStorage (__uid2_advertising_token) for persistence
Header Bidding: Prebid shares UID2 tokens with bidders automatically

This example demonstrates how a content publisher can integrate UID2 with Prebid.js for header bidding, using client-side token generation. For documentation, see the UID2 Client-Side Integration Guide for Prebid.js. [Source Code]

UID2 Integration Status

Ready for Targeted Advertising: ? Indicates whether a valid UID2 token is present and can be used for personalized ad targeting.
Advertising Token: ? The encrypted UID2 token that is passed to ad systems without exposing raw user identity.
Is Login Required? ? Indicates whether a new UID2 token needs to be generated. Returns "yes" when no valid identity exists or the current identity has expired.
Has Opted Out? ? Shows whether the user has exercised opt-out, in which case no advertising token may be generated or used.

Prebid.js is configured to handle the entire token lifecycle—generation, storage, and automatic refresh.
