Submitting Credit Card Transactions

Submitting Sale Transactions

zero dollar authorization (TRXTYPE=A). For details, see “Submitting Account

Verifications” on page 64.

Submitting Sale Transactions

The sale transaction (TRXTYPE=S) charges the specified amount against the account, and

marks the transaction for immediate fund transfer during the next settlement period. PayPal

submits each merchant's transactions for settlement on a daily basis.

NOTE: PayPal Payments Advanced and Payflow Link users cannot submit sale transactions

unless they obtain the Payflow SDK.

When To Use a Sale Transaction

A sale transaction is best suited to businesses that provide immediate fulfillment for their

products or services. If your business does not provide immediate fulfillment, credit card

association rules recommend that you use an authorization and a delayed capture transaction.

For details, see “Submitting Authorization/Delayed Capture Transactions” on page 65. To

recharge a credit card when you are not storing the credit card information in your local

database, you can perform a new reference transaction based on a Sale transaction.

NOTE: PayPal Payments Advanced and PayPal Payments Pro merchants using Fraud

Protection Service (FPS) should process their transactions as Authorizations with

Delayed Capture instead of a Sale. FPS transactions are treated as authorizations and

if the transaction is submitted as a Sale, Payflow auto-captures such transactions

approximately every two hours, which may result in a 2-hour or more delay in settling

the transaction.

Additional Parameters For Sale Transactions

To perform a sale transaction, pass the following parameters:

 ACCT

 AMT

 EXPDATE

NOTE: The pinless debit tender type requires essentially the same parameters as a credit card

transaction. In addition to the values required by all transactions, pass values for the

ACCT and AMT parameters. The First Data Merchant Services (FDMS) South

processing platform supports sale and credit transactions only.

Typical Sale Transaction Parameter String

The following is a typical NVP string passed in a sale transaction.
