@Shyfoox Apologies, I did not realize that ROBLOX does not allow access to API’s from in-game. If you want to use the API from in-game you need to use a proxy server, or set up your own server that handle’s GET requests and returns a response body.
If you are not able to set one up/get access to one take a look at this tutorial. I cannot however guarantee that it still works though.
