11 - Reversal Request

The Reversal Request includes most of the data that is present in the CPHA3 request. Only optional elements relating to cardholder information have been eliminated. Only the Client ID and JHN are supported in the message as optional elements. There is only one new field that is not present in CPHA3 today as shown below.

The Bundle and Message Header information is the same for all request messages. Only the value of the MessageHeader.event ID will change to reflect the type of message being processed.
