Credit Card Transactions
Submitting Voice Authorization Transactions
z The TRANSSTATE is set to 0 to prevent these types of transactions from being credited,
voided, or captured.
See “VERBOSITY: Viewing Processor-Specific Transaction Results” on page 139 for
details on TRANSSTATE.
NOTE: RESULT value 4, Invalid Amount, is returned if the processor does not support
Account Verifications.
When To Use Account Verification
Use an 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 “Recharging to the Same Credit Card (Reference Transactions)” on page 40.
Example Account Verification
This is an example of account verification:
TRXTYPE=A&TENDER=C&USER=SuperUser&PWD=SuperUserPassword&VENDOR=Super
User&PARTNER=PayPal&ACCT=4111111111111111&EXPDATE=0712&CVV2=123&AMT=
0.00&CURRENCY=USD&STREET=123 Main St.&ZIP=11232&VERBOSITY=MEDIUM
This is the response:
RESULT=0&PNREF=V79E1E4610CE&RESPMSG=Verified&AUTHCODE=010101&AVSADDR
=Y&AVSZIP=Y&CVV2MATCH=Y&HOSTCODE=00&PROCAVS=Y&PROCCVV2=M&IAVS=N
Submitting Voice Authorization Transactions
A Voice Authorization (TRXTYPE=F) transaction is a transaction that is authorized over the
telephone from the processing network.
NOTE: The PayPal processor does not support Voice Authorization transactions.
When to Use a Voice Authorization Transaction
Some transactions cannot be authorized over the internet (for example, high dollar amounts)
and require manual authorization. These transactions generate RESULT value 13 and are called
Referral transactions.
In these situations, you contact the customer service department of your merchant bank and
provide the payment information as requested. If the transaction is approved, the bank
provides you with a voice Authorization code (AUTHCODE) for the transaction..
Once a Voice Authorization transaction has been approved, it is treated like a Sale transaction
and is settled with no further action on your part.
