API Fields Formatting Restrictions Unless otherwise noted, all fields are order and case insensitive and the fields accept special characters such as @, #, and %. Values for request-level and offer-level fields must not contain carets (^) or colons (:). However, they can contain embedded spaces and any other printable characters. When you use more than one consecutive space, CyberSource removes the extra spaces.
