Optional Fields for Checking Enrollment in Payer Authentication

These fields are usually optional when you verify enrollment for a Payer Authentication transaction. In certain circumstances, the information provided by an optional field might be required before a transaction can proceed. Those optional fields that are sometimes required are also listed as required fields with the circumstance described.

merchantDefinedData_mddField_1
to
merchantDefinedData_mddField_5
These fields override the old merchant-defined data fields. For example, when you use the obsolete field
merchantDefinedData_field5
and the new field
merchantDefinedData_mddField_5
in the same request, the new field value overwrites the value specified in the obsolete field.
Merchant-defined data fields are not intended to and must not be used to capture personally identifying information. Accordingly, merchants are prohibited from capturing, obtaining, and/or transmitting any personally identifying information in or via the merchant defined data fields. Personally identifying information includes, but is not limited to, address, credit card number, Social Security number, driver's license number, state-issued identification number, passport number, and card verification numbers (CVV, CVC2, CVV2, CID, CVN). When a merchant is discovered capturing and/or transmitting personally identifying information via the merchant-defined data fields, whether intentionally or accidentally, the merchant's account is immediately suspended, resulting in a rejection of any and all transaction requests submitted by the merchant after the point of suspension.
