      Set up Publisher restrictions in the Didomi Console

      đź“• IAB TCF version 2 allows publishers to set restrictions on the purposes and legal basis IAB vendors use.

      This is useful for restricting the purposes declared by an IAB vendor and/or modifying the legal basis on which it is based.

      You will need to specify the purpose(s) to which you wish to apply a restriction and the vendor(s) to which the restriction should apply.

      Didomi currently supports four types of restrictions:

      • Allow purpose - allow vendors to process data for the specified purpose.
      • Disallow purpose - do not allow vendors to process data for the specified purpose.
      • Require consent - only allow a purpose to be processed with consent as a legal basis.
      • Require legitimate interest - only allow a purpose to be processed with legitimate interest as a legal basis.

      These restrictions can be managed in the Didomi console directly and are possible for web notices only.

      Mobile Applications

      If you wish to use publisher restrictions on a Mobile application, please update your SDK to at least: 

      • 1.25.0 (Android)
      • 1.37.0 (iOS)

      ✍️ Please note that, due to TCF V2 technical specifications, publisher restrictions are heavy and will increase the size of your euconsent-v2 cookie. In some cases, the cookie will be too large for a browser, which generally has a 4096 byte limit.

      As a result, the browser will be unable to store the cookie and TCF V2 will not work properly (this explains why you could encounter errors related to publisher restrictions in your browser console).

      đź“° Please also bear in mind that Special Features ("Use precise geolocation data" and "Actively scan device characteristics for identification") do not work based on legitimate interest. For this reason, neither "Require consent" nor "Require legitimate interest"  should be applied to these features.
