AcceptorDiagnosticResponseV08

caaa.014.001.08

The AcceptorDiagnosticResponse message is sent by the acquirer (or its agent) to provide to the acceptor the result of the diagnostic request.

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 AcceptorDiagnosticResponseV08 implementation follows a specific implementaiton pattern. First of all, AcceptorDiagnosticResponseV08 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorDiagnosticResponseV08Document implements IOuterDocument. Because AcceptorDiagnosticResponseV08 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorDiagnosticResponseV08.

classDiagram
    class IOuterRecord
    AcceptorDiagnosticResponseV08 --|> IOuterRecord : Implements
    AcceptorDiagnosticResponseV08Document --|> IOuterDocument~AcceptorDiagnosticResponseV08~ : Implements
    class IOuterDocument~AcceptorDiagnosticResponseV08~ {
        AcceptorDiagnosticResponseV08 Message
     }
  

Document wrapper for serialization

The only real purpose AcceptorDiagnosticResponseV08Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.014.001.08’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorDiagnosticResponseV08.ToDocument() method. The returned AcceptorDiagnosticResponseV08Document 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.014.001.08">
    <AccptrDgnstcRspn>
        <Hdr>
            <!-- Header inner content -->
        </Hdr>
