Hope everything is well! If you haven’t already looked at it, I would recommend looking at the operations listed in the documentation attached below. I believe this should help you to retrieve the qs file.
In regard to your other question, I do not believe it is possible to generate it simply by zipping up the contents. The only way is through an API call. Let me know if this helps or if there is any confusion following the steps!
This should give you a download link for the respective qs file. Feel free to check the link in my last post if you’d like to know more capabilities and other specifics regarding the API. Hope this helps!
