BALAMT Response Parameter and Stored Value Cards
BALAMT is a parameter that may be returned by transactions meeting Card Acceptance
Processing Network (CAPN) requirements when that transaction involves a stored value card.
Stored value cards typically are offered as “gift” cards, allowing the user to spend any amount
up to the balance remaining on the card. BALAMT returns the balance on the card provided
that the card is active and is not compromised. If the card is used to purchase merchandise
exceeding the card balance, American Express declines the transaction and returns the card
balance in BALAMT.
For details on American Express CAPN request transaction parameters, see Appendix A,
“Processors Requiring Additional Transaction Parameters.”
American Express CAPN Stored Value Card Example
The Authorization request is for a purchase of 123.00.
TRXTYPE=A&TENDER=C&PWD=x1y2z3&PARTNER=PayPal&VENDOR=SuperMerchant&USER=Supe
rMerchant&ACCT=5555555555554444&EXPDATE=0308&AMT=123.00&STREET=5199
MAPLE&ZIP=94588
Because the response returns a BALAMT of 99.00, the Authorization is declined.
