This appendix describes the SCMP (Simple Commerce Message Protocol) API fields that you can use to access Cybersource Payer Authentication services. SCMP API is a legacy name-value pair API that is supported for merchants who have already implemented it. If you are new to Cybersource and want to connect to services, use the Simple Order API.
Unless otherwise noted, all fields are order and case insensitive and the fields accept special characters such as @, #, and %.

Request-level and offer-level field names and values must not contain carets (^) or colons (:). However, they can contain embedded spaces and any other printable characters. If you use more than one consecutive space, the extra spaces will be removed. For Atos, the bill_ fields must not contain colons (:). |
