I have a Minecraft server and was wondering if there's a way to create an automated store with digital 'VIP packs', that once bought will then send the customer a code (generated automatically and randomly) that ten the customer can put into the game to activate their VIP account or another way I thought of was: the customer puts their account's nickname and then the account with that nickname automatically gets updated into the VIP account (allowing the player to get digital money on the server, some perks like flying and so on). What do you think? Is there a way to do it? How to do it? Will it cost me to pay monthly for any app?
