Payer Authentication Examples

These examples list the API fields that are required or optional for the Setup, Check Enrollment, and Validate Authentication services. An example of a request payload and a successful response that occur with each service are provided. There are three types of examples when working with payer authentication:
  • Primary Account Number (PAN): Illustrates how the payer authentication services work with customer PANs during transactions.
  • Tokens: Illustrates how the payer authentication services work when using different types of tokens.
  • 3RI: Illustrates how the payer authentication services work with merchant initiated transactions.
In certain circumstances, some payment card companies and some countries require that additional information than the normal information be collected when authenticating the customer. These circumstances, and the API fields to use in those circumstances, are noted for each use case.

Payer Authentication Examples

Non-Payment Authentication

Non-Payment Authentication (NPA) requests enable a merchant to authenticate a customer without a transaction. A non-payment use case can be used for such tasks as adding a card to a merchant website, updating cardholder information on file, or to verify a cardholder's identity when creating a token for future use. The same authentication used during the checking enrollment process is used for NPA. Non-payment use cases are enabled using a combination of the
payerAuthEnrollService_messageCategory
 and
payerAuthEnrollService_authenticationIndicator
 values. For example to add a card to a loyalty program, set the Message Category value to
02
 and the Authentication Indicator value to
04
. For other possible NPA use cases, refer to the other possible values for
payerAuthEnrollService_messageCategory
 value must be set to
02
 (non-payment authentication) to specify that the authentication is not for a transaction.

Merchant-Initiated Transactions

A 3RI transaction is an EMV 3-D Secure transaction that is initiated by the merchant instead of the cardholder. The merchant keeps the payment data from the initial payment so that the cardholder does not have to be present for subsequent 3RI transactions. Having the payment details from a previous transaction enables the merchant to obtain a new Cardholder Authentication Verification Value (CAVV) to authenticate when authorizing future payments.
The authorization request contains the
payerAuthEnrollService_deviceChannel
 field. This process can be applied to these types of transactions:
  • Recurring payments: payments occur at regular intervals for an indefinite interval like subscription services.
  • Installment payments: payments occur at regular intervals for a fixed interval.
  • Refunded purchases: the cost of an item is refunded before the item is received. Any charges for damage or missing items can be charged back to the customer using a 3RI transaction.
  • Delayed shipments: an ordered item is out of stock delaying the shipment until the item is back in stock.
  • Split payments: an order is fulfilled in split shipments rather than in a single shipment because one of multiple items in the order is temporarily out of stock.
  • Multiple party commerce: a single entity or party makes multiple transactions with different merchants, for example, a travel agent booking flights, hotels, and tour excursions.
  • Unknown final transaction amount: extra charges are made to the customer for items such as hotel services, driving citations, or tips.
