Logging Transaction Information
A record is maintained of all transactions executed on your account. Use PayPal Manager to
view the record and use the information to help reconcile your accounting records.
NOTE: This record is not the official bank statement. The activity on your account is the
official record.
In addition, it is strongly recommended that you log all transaction results (except for check
information) on your own system. At a minimum, log the following data:
PNREF (called the Transaction ID in PayPal Manager reports)
Transaction Date
Transaction Amount
If you have any questions regarding a transaction, use the PNREF to identify the transaction.
Audit Trail and Transaction Logging
The Buyer Authentication server logs Verify-Enrollment transactions, PAREQ values, and
PARES values.
Verify Enrollment Transactions
Verify Enrollment transactions are logged when all of the following items occur:
The merchant passes data needed to perform buyer authentications.
The server connects to Visa or MasterCard and gets a meaningful response (card
enrollment AUTHENTICATION_STATUS=E, U, or X). If status is Y, then the PAREQ
value is logged along with the Verify Enrollment transaction data.
Otherwise, the transaction is not logged.
Validate Authentication Transactions
The Buyer Authentication server will log the PARES value only when all of the following
items occur:
There is a matching PAREQ (by Message ID, not by content) in the database.
There is no other PARES with the same Message ID in the database. This means that if a
duplicate PARES is submitted, it is logged only once.
