GPP consent string received but downstream requesting EU TCF macro

[garylonghalds]

In EU, we are facing cases where we either receive either GPP or EU TCF string (and some rare occasions both) from upstream. Our downstream partners raise request via macros for either GPP or EU TCF string.

1. Is there any guidance on what to do for cases when we have received only a GPP string from a publisher/CMP but the downstream partners are using a EU TCF Macro
2. The vice versa usecase where we receive only a EU TCF string but received request for consent strings via a GPP Macro?

in theorie you can convert them 1:1 but at least from TCF policy it states that only a CMP should create tc strings. hence the only way out here would be to always receive/send both
