Check Enrollment Response Fields and Their Equivalent Authorization Request Fields {#pa2-ccdc-combining-mapping-check-enroll-auth-fields}
=========================================================================================================================================

When a customer is authenticated without a challenge, the transaction can be authorized either in the same request or in a separate authorization request. Whether authorization occurs in the same request or a separate request, the values from the check enrollment response must be passed to the authorization request to qualify for a liability shift. This table matches the check enrollment fields with their equivalent authorization fields. Sometimes a check enrollment response field is the same field used in the authorization request.  
Be sure to include the following card-specific information in your authorization request:

* For Visa, JCB, China UnionPay, Elo,Diners Club, Discover, and American Express include the *CAVV*.
* For Mastercard only, include the collection indicator and the *AAV* (also known as *UCAF*).
