I have links to the same survey customized by customer service rep. This allows me to see which rep is being rated. After the survey link insert a "?", then the variable name, then "=", then the specific variable. For example SV_1234AbcnxJ5T?Name=Alan&City=Dallas&Street=1st. You do have to include Name, City, and Street as embedded data, but all the data comes from the link, not your contact list.
We were able to fix this issue, so for future reference if anyone else runs into an issue similar to this, here's the solution. The task object did not have permission to access Qualtrics. Starting from the account gave us the permission we needed, but starting from the task did not.
