Prebid supports the IAB’s Transparency and Consent Framework (TCF) version 2.x. Prebid provides modules and features as a set of tools that may help publishers achieve compliance with the EU GDPR regulation.
The key changes from TCF 1.1 are:
- More defined ‘purposes’.
- More flexibility for the legal bases used by vendors.
- Different in-page JavaScript API.
TCF 2.2 had no changes that affected Prebid.js.
