The first step is to copy that JSON into a Mendix JSON Structure in Studio Pro.

The next is to create an Import Mapping. As your structure is so simple, using automatic mapping should be the easiest approach.

Now you have the structure, you can use it in a Published REST Service to import data or directly in a microflow using an Import With Mapping action.

I hope this helps. Good luck!
Excellent. Thank you Robert very much!
