Each transaction type has additional parameter requirements, as listed in the following

sections. Transaction responses are described in Chapter 4, “Responses to Credit Card

Transaction Requests.”

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.

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, then credit card

association rules recommend that you use an Authorisation and a Delayed Capture transaction.

For details, see “Submitting Authorisation/Delayed Capture Transactions” on page 25. If you

need to recharge a credit card and you are not storing the credit card information in your local

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

see “Submitting Authorisation/Delayed Capture Transactions” on page 25.

Additional Parameters for Sale Transactions

To perform a Sale transaction, you are required to pass the following parameters:

ACCT

AMT

EXPDATE

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

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

for the ACCT and AMT parameters.
