Need help with Gameflip API

So, I was hoping to use Gameflip API to list TF2 items with the purpose of sending items through bot transfer. I have looked at the articles regarding Gameflip API from github and the API document but it doesn’t quite explain where to put the code in. I downloaded GIt, node js, and python but I don’t know where to type the code the articles are asking me to do. If anyone can explain to me what to do, I would greatly appreciate it. Thanks.

If no one here can help me, does anyone from Gameflip who knows about how this works can help me out? I will greatly appreciate it. I tried to follow the directions on but it doesn’t really make sense to me. I keep getting error messages.

create notepad name it like tfcap.js wrote ur code in

The problem is, I don’t know where the code goes into. I don’t even think I even downloaded the sample code using git clone correctly either.
