Non-Payment Authentication {#pa2-check-enroll-use-npa-intro} ============================================================ 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. The payerAuthEnrollService_messageCategory value must be set to `02` (non-payment authentication) to specify that the authentication is not for a transaction.
