:confirmation_number :: :string

An optional 10 to 11 digit numeric-only string determining the confirmation code at applicable convenience stores.

:expires_after_days :: :integer

The number of calendar days (between 1 and 60) after which Konbini payment instructions will expire. For example, if a PaymentIntent is confirmed with Konbini and expires_after_days set to 2 on Monday JST, the instructions will expire on Wednesday 23:59:59 JST.

:expires_at :: :integer

The timestamp at which the Konbini payment instructions will expire. Only one of expires_after_days or expires_at may be set.

:product_description :: :string

A product descriptor of up to 22 characters, which will appear to customers at the convenience store.

:setup_future_usage :: :string

Indicates that you intend to make future payments with this PaymentIntent's payment method.

Providing this parameter will attach the payment method to the PaymentIntent's Customer, if present, after the PaymentIntent is confirmed and any required actions from the user are complete. If no Customer was provided, the payment method can still be attached to a Customer after the transaction completes.

When processing card payments, Stripe also uses setup_future_usage to dynamically optimize your payment flow and comply with regional legislation and network rules, such as SCA.
