Batch and List Refund Operations

Batch: You can submit a transaction initiated via a batch payment order, along with its MerchantUniqueCode, to the Paywall APIs to process refunds for all transactions under that batch payment.

List: You can send payments identified by your MerchantUniqueCode values (which may be from batch or single transactions) as a single list to Paywall’s batch refund service. This allows you to complete refunds for all transactions with a single API call and receive a single callback notification from Paywall in response.
