AcceptorCancellationResponseV09

caaa.006.001.09

The AcceptorCancellationResponse message is sent by the acquirer (or its agent) to an acceptor (or its agent), to return the outcome of the cancellation request. If the response is positive, the acquirer has voided the financial data from the captured transaction.

Message Construction

Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AcceptorCancellationResponseV09 implementation follows a specific implementaiton pattern. First of all, AcceptorCancellationResponseV09 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCancellationResponseV09Document implements IOuterDocument. Because AcceptorCancellationResponseV09 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCancellationResponseV09.

classDiagram
    class IOuterRecord
    AcceptorCancellationResponseV09 --|> IOuterRecord : Implements
    AcceptorCancellationResponseV09Document --|> IOuterDocument~AcceptorCancellationResponseV09~ : Implements
    class IOuterDocument~AcceptorCancellationResponseV09~ {
        AcceptorCancellationResponseV09 Message
     }

Document wrapper for serialization

The only real purpose AcceptorCancellationResponseV09Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.006.001.09’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCancellationResponseV09.ToDocument() method. The returned AcceptorCancellationResponseV09Document value will serialize correctly according to ISO 20022 standards.

Sample of message format

This is an abbreviated version of what the message should look like.

<Document xmlns="urn:iso:std:iso:20022:tech:xsd:caaa.006.001.09">

        <Hdr>

            <!-- CancellationResponse inner content -->
        </CxlRspn>
