Hi, i just posted my first api listing and everything works fine. but now i really want to make a script, so i dont have to copy paste them all over again. can someone help me or give me a sample where i just have to fill it with my key and secret? is there also a way to post multiple listings in one script? i would even pay u guys some cash, if u help me 
there is no possible way to make a key script for gameflip, you would have to make your own, and the only way to post multiple at once is buy keeping all your placements in the draft.
