Submitting Credit Card Transactions

Submitting Account Verifications

54 31 July 2012 Gateway Developer Guide and Reference

Submitting Account Verifications

Account verification, also known as zero dollar authorization (TRXTYPE=A), verifies credit

card information. While you pass TRXTYPE=A for account verification and normal

authorization, account verification differs from authorization in the following ways:

 Always pass the AMT value 0. If you pass any other amount, the transaction becomes a

normal authorization that places a hold on the cardholder’s open-to-buy limit.

 Although the RESULT value returned is 0 (Approved), the RESPMSG value returned is

Verified rather than Approved.

NOTE: Payflow returns RESULT value 4, Invalid Amount, if the processor does not support

account verifications.

When To Use Account Verifications

Use account verification to validate account numbers and other authentication elements such

as CVV2 and AVS. You can also use an account verification as a reference transaction. See

“Submitting Reference Transactions (Tokenization)” on page 66.
