Privacy-Related Guides: TCF v2.3 Compliance for Publishers

AB Europe released Transparency & Consent Framework (TCF) v2.3 on June 19, 2025. This version introduces a new requirement that directly affects how Commerce Grid processes bid requests: vendors must now be disclosed in your Consent Management Platform (CMP) — not only consented to.

In line with the IAB TechLab policy effective February 28, 2026, Commerce Grid applies the following policy for all traffic where GDPR applies:

• The TCF consent string must be TCF v2.3-compliant, meaning the DisclosedVendors segment must be present and non-empty.

• The DisclosedVendors segment must include Criteo (GVL ID: 91).

If either condition is not met, Commerce Grid will drop the bid request and cannot fire user syncs for that traffic. This guide explains what you need to do to remain eligible for Commerce Grid demand.
