Let's say I want to create a mobile app where people will participate in winning one of N limited edition gin bottles / shoes / jewelry / any physical goods based on some chance. And let's say I don't want to develop / host my own backend for this. Are there some kind of lottery / lootbox management platforms where I would e.g. just create some kind of instance of N unique IDs / goods, set up some drop chance and this instance would be exposed as an API to my mobile app to call? And when somebody wins, there would need to demonstrate the campaign host some kind of non-forgeable voucher / QR code they're given upon winning? Free or payed both fine.
