Submitting Credit Card Transactions

Submitting Void Transactions

72 31 July 2012 Gateway Developer Guide and Reference

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 referral transactions generate RESULT value 13.

In these situations, you contact the customer service department of your merchant bank and

provide the payment information as requested. If the bank approves the transaction, the bank

provides you with a voice authorization code (AUTHCODE) for the transaction..

On approval, a voice authorization transaction is treated like a sale transaction and is settled

with no further action on your part.

Like sale transactions, you can void approved voice authorizations before settlement occurs.

Required Voice Authorization Transaction Parameters

To perform a voice authorization transaction, pass the AUTHCODE provided by your merchant

bank.

The following is an example Voice Authorization request parameter string:4

TRXTYPE=F&TENDER=C&PARTNER=PayPal&VENDOR=SuperMerchant&USER=SuperMerchant&P

WD=x1y2z3&AUTHCODE=AB3456&ACCT=5555555555554444&EXPDATE=1215&AMT=123.00&VER

BOSITY=HIGH

Submitting Void Transactions

The void transaction (TRXTYPE=V) prevents authorizations from being captured, and delayed

captures, sales and voice authorizations from being settled.

You cannot void another void transaction or any inquiry type transactions. The void

transaction and the original transaction will not appear on the customer’s statement.

PayPal will issue an authorization reversal as part of the void transaction for debit and credit

cards if the processor supports it. Because the bank or issuer ultimately decides whether to

honor authorization reversals, there is no accurate way to determine if an authorization

reversal was completed and the hold on funds has been removed.

Parameter Description

AUTHCODE (Required for voice authorizations) Returned only for approved voice

authorization transactions. AUTHCODE is the approval code received over the

phone from the processing network.

Limitations: 6 alphanumeric characters
