Submitting Credit Card Transactions
Submitting Inquiry Transactions

Fields Copied From the Original Transaction Into the Credit Transaction
The following fields are copied from the original transaction into the credit transaction (if they
exist in the original transaction). If you provide a new value for any of these parameters when
submitting the credit transaction, the new value is used. (Exceptions are ACCT, EXPDATE, and
SWIPE. These parameters retain their original values.)
NOTE: These fields are not copied for referenced credits: TAXAMT, TAXEXEMPT, DUTYAMT,
FREIGHTAMT, and (for American Express only) DESC4.
NOTE: For processors that use the RECURRING parameter: If you set the RECURRING
parameter to Y in the original transaction, this setting is ignored when forming the
credit transaction.
