NEW!   We now have our Interactive tool for this section.

Restores all or part of the funds from a Purchase, Pre-Authorization Completion or Force Post transaction to the cardholder's card. 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 transaction object definition

Refund refund = new Refund();

HttpsPostRequest object for Refund transaction

HttpsPostRequest mpgReq = new HttpsPostRequest();


Refund transaction object mandatory values

Value Type Limits Set method Description
Order ID String 50-character alphanumeric refund.setOrderId(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 refund.setAmount(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 varchar refund.setTxnNumber(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.
E-Commerce indicator String 1-character alphanumeric refund.setCryptType(crypt);

Describes the category of e-commerce transaction being processed. Allowable values are:

  • 1 - Mail Order / Telephone Order—Single
  • 2 - Mail Order / Telephone Order—Recurring
  • 3 - Mail Order / Telephone Order—Instalment
  • 4 - Mail Order / Telephone Order—Unknown classification
  • 5 - Authenticated e-commerce transaction (VBV)
  • 6 - Non-authenticated e-commerce transaction (VBV)
  • 7 - SSL-enabled merchant

In Credential on File transactions where the request field e-commerce indicator is also being sent: the allowable values for e-commerce indicator are dependent on the value sent for payment indicator, as follows:

if payment indicator = R, then allowable values for e-commerce indicator: 2, 5 or 6
if payment indicator = C, then allowable values for e-commerce indicator: 1, 5, 6 or 7
if payment indicator = U, then allowable values for e-commerce indicator: 1 or 7
if payment indicator = Z, then allowable values for e-commerce indicator: 1, 5, 6 or 7

Refund transaction object optional values

Value Type Limits Set method Description
Customer ID String 50-character alphanumeric refund.setCustId(custid); This can be used for policy number, membership number, student ID, invoice number and so on.

This field is searchable from the Moneris Merchant Resource Centre.
Status Check Boolean true/false mpgReq.setStatusCheck(status_check); Status Check is a connection object value that allows merchants to verify whether a previously sent transaction was processed successfully.
Dynamic Descriptor String true/false refund.setDynamicDescriptor(dynamic_descriptor); Merchant-defined description sent on a per-transaction basis that will appear on the credit card statement appended to the merchant’s business name.
