setupFutureUsage property
Indicates that you intend to make future payments with this PaymentIntent's payment method.
If present, the payment method used with this PaymentIntent can be attached to a Customer, even after the transaction completes.
Use on_session if you intend to only reuse the payment method when your customer is present in your checkout flow. Use off_session if your customer may or may not be in your checkout flow. See saving card details during payment to learn more.
Stripe uses setup_future_usage to dynamically optimize your payment flow and comply with regional legislation and network rules. For example, if your customer is impacted by SCA, using off_session will ensure that they are authenticated while processing this PaymentIntent. You will then be able to collect off-session payments for this customer.
