Hi,
I have seen some conversations about needing to have multiple unique anonymous links. We would like to track who is responding via social media, email, or 'other'. Please keep in mind that I am not able to upload contacts to use the social media or email features in Qualtrics. When I tried to edit the anonymous URL with '?source=email', it did not work. I put 'source' into the top of my survey flow as an embedded field with no value assigned.
Has anyone had any experience with this?
