* `expand` - Specifies which fields in the response should be expanded.
* `metadata` - Set of [key-value pairs](https://docs.stripe.com/api/metadata) that you can attach to an object.

All keys can be unset by posting an empty value to `metadata`.
* `payment_intent` - ID of the PaymentIntent to refund. Max length: 5000.
* `refund_application_fee` - Boolean indicating whether the application fee should be refunded when refunding this charge. If a full charge refund is given, the full application fee will be refunded.

* `refund_payment_config` - Configuration overrides for this refund, such as customer cancellation settings.
