I have a survey that respondents take every few months. I'd like to use the Qualtrics REST API to run a GET request to retrieve the response for a specific user (identified by a unique identifier that exists in my system and in the survey embedded data)for that user, the response for a specific question over a given time frameIs this feasible with the latest Qualtrics API? Any recommended guides / support article I missed? Thanks!

Yes, you need to program the API on your end which gets the unique identifier and checks the time frame, and return the response for the question.
