I saw your facebook post, assuming you're still looking for answers here. I doubt you'll find anyone that has experience with qualtrics, it's a relatively unknown platform.
HOWEVER, you can find resources on reading REST API data into filemaker:
This module gets google calendar data via REST
Basic of using Insert From URL script in filemaker to insert data from a remote source.
The BaseElements plugin that can be used to execute REST commands and retrieve a result.
If you want to hire a consultant that's familiar with those technologies, that would most likely be easier to find than someone that has specific experience with qualtrics.
