Combining Services

You can combine the enrollment check and card authorization services into the same request or use a separate request for each service. Using the same request is recommended.

Same request: Attempts to authorize the card after authentication are made if step-up payer authentication is not required. 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 step-up authentication is required, processing stops to allow completion, and authorization is not called. This integration method is recommended.

Separate requests: Manually include the enrollment check result values (Enrollment Check Response Fields) in the authorization service request (Card Authorization Request Fields). Refer to the fields that are listed in the table.

Depending on your card type, and whether it is a 3-D Secure 1.0 or 2.x transaction, you might not receive the XID. If you receive this field under a frictionless scenario, it is required for authorization.

This table lists these fields.
