Refund object to refund customers. For compliance reasons, Subscribe allows refunds for no more than the amount of the original transaction, but supports both full and partial refunds of the original charge.
Subscribe automatically creates transactions for recurring billing from AutoBill objects. Fetch these transactions from Subscribe by calling Transaction->fetchDeltaSince(), or search for them on the Subscribe Portal. Use transaction data as a basis for your customer refund. Search by merchantTransactionId for an AutoBill-related transaction and for the refund amount.
