Submit a full or partial refund for an order that has been captured.

A successful synchronous response to this request does not mean the refund has been successfully executed, but rather that the refund has been added to the system and will be attempted. If the refund cannot be added to the system an error will be synchronously returned in the response to this message. Once the refund has been attempted, a notification will be sent indicating success or failure of the refund attempt.
