link the survey of a website opposition project to my directory

Hii,

You need to get the email id or if you’re getting respondents to login you can get that as well. Post you have that you can link to XM Directory. 

Else you can ask email, add authenticator and you should be able to link them.

Hope it helps!

thanks for your answer, i'm making them login and their id is the same as i have in external reference in qualtrics, but still it doesn't get the directory data.

I also put this code on top of the one that generates the intercept

if(typeof QSI === "unlimited") {

     QSI = {};

     QSI.config = {

       externalReference: extRef

     };

 }
