So the API you are connecting to is properly written then (and does all the database handling), you are basically just calling it from your scripts? That’s totally fine then, but those scripts are the easiest part. Usually done in something like a Python tool, but Powershell works too I guess (just more limited in what it can do).
I’m curious though how you managed to get ChatGPT to do this kind of work, did you throw the full API definition into it, then ask it to create a Powershell application to do x, y and z with helper functions?
My viewpoint is from the side of a backend developer (like the API you are using), I wouldn’t trust ChatGPT to get anything right there (especially with cross system communication, between Microservices and to the databases). We spend probably a third to half of the time on security, reliability and performance, just getting the code to do what you want is the easiest part of the job.
