Gameflip - Using Api key

Hello Flippers! I’ve been using Gameflip’s API key to post Rocket League listings for a few months and I’ve been wondering if I can use Gameflip’s API key to post TF2 items? If I can, can you please give me a link where I can get the proper .js file?

Here you can find available API’s

Yeah, that’s fine. I think I saw someone who did it.

Can you link me his profile? I want to ask him how to do it
