Performing Credit Card Transactions

Recharging to the Same Credit Card (Reference Transactions)

34 Payflow Pro Developer’s Guide

If you attempt to perform a reference transaction in an account for which

reference transactions are disallowed, result code 117 is returned. See PayPal

Manager online help for instructions on setting reference transactions and

other security features.

Sale and Authorisation transactions can make use of a reference transaction as a source of

transaction data. PayPal looks up the reference transaction and copies its transaction data into

the new Sale or Authorisation transaction. With the exception of dollar amount data, which

triggers a filter if out of range, reference transactions are not screened by Fraud Protection

Services filters.

IMPORTANT: When PayPal looks up the reference transaction, neither the transaction

being referenced nor any other transaction in the database is changed in any

way. That is, a reference transaction is a read-only operation—only the new

transaction is populated with data and acted upon. No linkage is maintained

between the reference transaction and the new transaction.

You can also initiate reference transactions from PayPal Manager. See PayPal Manager online

help for details.

Transaction Types that Can Be Used as the Original Transaction

You can reference the following transaction types to supply data for a new Sale or

Authorisation transaction:

z Authorisation (To capture the funds for an approved Authorisation transaction, be sure to

perform a Delayed Capture transaction—

not a Reference transaction.)

z Credit

z Delayed Capture

z Sale

z Voice Authorisation (The Voice Authorisation code is not copied to the new transaction)

z Vo i d

Fields Copied From Reference Transactions

The following fields are copied from the reference transaction into the new Sale or

Authorisation transaction (if they exist in the original transaction). If you provide a value for

any of these parameters when submitting the new transaction, then the new value is used.
