Requesting the Check Enrollment Service (SDK)

After the SDK completes the device collection from your mobile application, and after the customer clicks the Buy button, you must make a back-end, server-to-server call to request the Enrollment Check service.
The Check Enrollment service verifies that the card is enrolled in a card authentication program. The merchant ID is included as part of the header, but these fields are required in the request:
  • billTo_city
  • billTo_country
  • billTo_email
  • billTo_firstName
  • billTo_lastName
  • billTo_postalCode
  • billTo_state
  • billTo_street1
  • card_accountNumber
  • card_cardType
  • card_expirationMonth
  • card_expirationYear
  • merchantID
  • merchantReference Code
  • payerAuthEnrollService_referenceID
  • payerAuthEnrollService_run
  • purchaseTotals_currency
  • purchaseTotals_grandTotalAmount
To reduce your issuer step-up authentication rates, you can send additional request data in order. It is best to send all available fields.
Use the enrollment check and card authorization services in the same request or in separate requests:
  • Same request:
    Cybersource
     attempts to authorize the card if your customer is not enrolled in a payer authentication program. In this case, the field values that are required to prove that you attempted to check enrollment are passed automatically to the authorization service. If authentication is required, processing automatically stops.
  • Separate requests: Manually include the enrollment check result values (Enrollment Check response fields) in the authorization service request (Card Authorization request fields).
Be sure to include the following card-specific information in your authorization request:
  • For Visa, American Express, JCB, Diners Club, Discover, China UnionPay, and Elo, include the CAVV.
  • For Mastercard only, include the collection indicator and the AAV (also known as UCAF).
These fields are listed in this table.
