Restores all or part of the funds from a Purchase, Pre-Authorization Completion or Force Post transaction to the cardholder's card. If the transaction is still in an open batch please refer to Purchase Correction. Unlike a Purchase Correction, after a Refund there is a record of both the initial charge and the refund on the cardholder's statement.

Refund mandatory values

Value Type Limits Variable Description
Order ID String 50-character alphanumeric order_id Merchant-defined transaction identifier that must be unique for every Purchase, Pre-Authorization and Independent Refund transaction. No two transactions of these types may have the same order ID.

For Refund, Completion and Purchase Correction transactions, the order ID must be the same as that of the original transaction.

The last 10 characters of the order ID are displayed in the “Invoice Number” field on the Merchant Direct Reports. However only letters, numbers and spaces are sent to Merchant Direct.

A minimum of 3 and a maximum of 10 valid characters are sent to Merchant Direct. Only the last characters beginning after any invalid characters are sent. For example, if the order ID is 1234-567890, only 567890 is sent to Merchant Direct.

If the order ID has fewer than 3 characters, it may display a blank or 0000000000 in the Invoice Number field.
Amount String 10-character decimal amount Transaction amount. Used in a number of transactions. Note that this is different from the amount used in a Completion transaction, which is an alphanumeric value.

This must contain at least 3 digits, two of which are penny values.

The minimum allowable value is $0.01, and the maximum allowable value is 9999999.99. Transaction amounts of $0.00 are not allowed.
Transaction Number String 255-character (variable character) txn_number Used when performing follow-on transactions. (That is, Completion, Purchase Correction or Refund.) This must be the value that was returned as the transaction number in the response of the original transaction.

When performing a Completion, this value must reference the Pre-Authorization. When performing a Refund or a Purchase Correction, this value must reference the Completion or the Purchase.
