How would you make a like counter?

The title explains it all, how can I make a like counter for my game? Is it possible? Would I need a API?

Please specify on what your goal is, is this counter some type of HTTP request?

There is something like this already on the devfourm

Please be a little more specific, would you like a button you click and it counts how many times someone has clicked that? Or would you like to display the total amount of likes the game has on Roblox? Or maybe something else, just please specify

Sorry for not being specific, I was talking about a surface GUI displaying the current likes that the game has on the GUI.
