How can you make in app purchase on Apple TV ?
On what device do you intend to make these purchases? Did you refer to the Apple TV box? If so, which model?

If an app on an Apple device says “buy this item for x amount of money”, or “subscribe to this service for y amount of money”, and you confirm that purchase, then often the corresponding amount will be billed to the pre-approved payment method that is linked to your Apple Account.
If an app chooses not to use the Apple payment processing, then it may be different, and it should be explained in the app how they intend for you to proceed.
