Would love to hear the explanation for that. When people use postman I'm wondering, why not use curl itself? Never looked into postman and know well enough even in C, a simple GET (or POST!) request is a few lines of code.
For one off requests, yeah there’s no point to something like that.
I see stuff like curl as a more advanced tool for people who already know what they are doing. In fact Postman even offers a curl "export" option that lets you see how to do whatever you have done in Postman, using curl instead. So arguably, it's also a good introduction to curl as well.
A set of curl scripts or a .http file (httpie) held in your project's git repository is IMO preferable, most editors allow you to run these directly from the editor.
