Validation Fields and their Equivalent Authorization Fields {#pa2-ccdc-combining-map-validate-auth-fields}
==========================================================================================================

When a customer is authenticated after a challenge, the transaction can be authorized in the same request or in a separate authorization request. Whether authorization is combined with validation or occurs in a separate request, the values from the validation response must be passed to the authorization request to qualify for a liability shift to the issuing bank. This table pairs the Validation field with its equivalent Authorization API field.  
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).
