There are two 3rd-party gems for accessing the API with Ruby:
- https://github.com/CambridgeEducation/qualtrics_api
- https://code.osu.edu/asctech/qualtrics-ruby-api-wrapper
The first has been abandoned by its creators as of 2018 and is in maintenance mode. The second has not seen an update in a year, and has documentation that is 3 years old and is no longer accurate. It may still work fine, but the README only appears to tell you how it used to work.
I only need to GET info, and only from a single survey, so my use case should be fairly simple.
