Submitting Purchasing Card Level 2 and Level 3 Transactions

About American Express Purchasing Card Transactions

144 31 July 2012 Gateway Developer Guide and Reference

Level 2 and Level 3 data is generally considered non-financial data. Lack of adequate data

may cause a transaction to be downgraded.

PayPal generally requires up to Level 2 information in an authorization transaction followed

by additional Level 3 data in the associated delayed capture transaction. A sale transaction

should include all Level 3 data since it is authorized and later settled.

Accepted BIN Ranges

Visa, MasterCard, and American Express publish specific Bank Identification Number (BIN)

ranges for purchasing cards. Sometimes the processor determines whether a card is a

purchasing card, for example, TSYS Acquiring Solutions. In other cases, the Gateway makes

the determination based on the BIN range (for example, FDMS South and American Express).

About American Express Purchasing Card Transactions

The information in this section applies to transactions processed by American Express not

necessarily to all American Express cards. Level 2 and Level 3 purchasing card rules may

differ for American Express card transactions processed by other processors such as

Paymentech or First Data Nashville.

Supported Transaction Types

You can submit Level 3 parameters with delayed capture, sale, credit, or force transactions.

Level 3 data in authorization transactions is ignored. The Gateway decides whether a

transaction meets Level 3 requirements during authorization.

Level 3 data is passed to the American Express processor only during settlement.

Level Description

Level 1 Function as normal credit cards and are authorized and associated with normal

transaction data in authorization and settlement. Any merchant who accepts credit

cards supports this level..

Level 2 Additional data regarding sales tax, customer code, purchase order number, invoice

number are captured at the point of sale. In most cases, this information is combined

with the merchant’s tax ID number, state, and postal code data and is then passed

through during settlement. For some processors and banks, however, a Level 2

authorization may include some of this data.

Level 3 Significant additional information such as line items, product codes, item

descriptions, unit price, unit quantities, and ship-to postal data are added to the Level

2 data to provide optimal reporting to buyers and sellers. Settlement transactions

typically carry Level 3 data.
