This is a little fast project i made for my gf because she drinks monster and wanted free codes lmao.
Below are the instructions.
To get started you need an account on the monster website. Use My Referal Code For 2 Free Codes. Code > GPMZKRKWTHGF https://musicapp.monsterenergyloyalty.com
register for an account there, Once on your redeem page open devloper console and go to the network tab.
try to redeem a code (10 charicters uppercase). you will see a request called claim. Open the request and the tokens are in the request headders. Just copy and paste its that simple.
This method does work i got a few codes so far but its SLOW so if you want to fork or make your own version using this code dont be a skid. dont sell this.
