Earlier quoted context omitted.
We used Postman but it got forbidden in our org for that reason, so no more. Can't say I really miss it. I personally prefer just using a jupyter notebook for these kinds of tasks. With a custom tool like this it becomes a dead end with the data. Maybe you want to decode it if it is on a binary format. Or you want to plot some basic stats?
This has always been my approach really. Use curl for basic stuff, use a full featured repl for deeper exploration. I use Ruby but same idea. I never quite saw enough value in tools like postman. Usually either what you are doing is trivial enough for vanilla curl or complex enough to warrant reaching for a general purpose programming language.
Instead, I just hacked together a small Python library, called all the APIs from there, and pushed to Git. Everyone on my team understands it, I have 100% control, and no cloud needed.
