The unmatched refunds functionality allows you to perform a credit card refund using the eCommerce API for cases where regular or extended refunds cannot be supported. With unmatched refunds, you initiate the credit without reference to a previous transaction.
Only users with Merchant Supervisor role are allowed to perform unlinked refunds.
Whenever the merchant requests to be able to perform unmatched refunds, the "Allow Unmatched Refunds" checkbox from the Payment Provider Contract (PPC) page in Verifone Central has to be ticked. This checkbox will be shown whenever the unmatched refunds are supported by the acquirer.
Note: For a user to be able to perform unlinked refunds, the feature needs be allowed at acquirer level as well.
The PAN, expiration date, transaction amount, merchant reference are the required fields for performing an unmatched refund/transaction.
Unmatched refunds is successfully performed even if the card/token of the cardholder is expired.
