Hi, I have an app where user can select an amount within range 20$ - 2500$ and purchase tokens worth that amount, so if he pays 520$ he gets 520 tokens. They can then use these tokens to unlock content within the app. As far as I've seen, in-app purchase doesn't allow custom price set by user. So does this mean we can use third-party payment services? If no, how can we achieve this using in-app purchase. Thank you.
