Using the Merchant-Initiated Reversals Feature

  1. Include the
    (MTI) field in your original request for a PIN debit purchase . The value of the merchant transaction ID must be unique for 60 days.
  2. When you do not receive a response message for your original transaction request, reverse the original transaction:
    1. Request the PIN debit reversal services as described in Reversing a Payment or Credit.
    2. Instead of including the request ID in your request message, include the
      field. The MTI field links your reversal request to your original request.
