Extended identifiers

CloudX now forwards publisher-provided UID 2.0, LiveRamp, and ID5 values on bid requests, so demand partners that use these identifiers can read them. Pass them with the existing setUserKeyValue API; no SDK update is required.

What’s new

  • UID 2.0: Pass the UID2 advertising token under uidapi.com.
  • LiveRamp: Pass the LiveRamp ATS envelope, not a RampID, under liveramp.com.
  • ID5: Pass the ID5 universal UID under id5-sync.com.
  • On the bid request: OpenRTB 2.6 bidders read user.eids, and OpenRTB 2.5 bidders read user.ext.eids.

Getting started

Set each value with setUserKeyValue on Android, iOS, Unity, React Native, or Flutter. CloudX doesn’t generate, decrypt, or replace these values. EUID tokens and Intent IQ IDs now pass through the same way. Read the extended identifier docs for each key.
