AcceptorCompletionAdviceResponseV06

caaa.004.001.06

The AcceptorCompletionAdviceResponse message is sent by the acquirer (or its agent) to acknowledge the acceptor (or its agent) of the outcome of the payment transaction, and the transfer the financial data of the transaction contained in the completion advice.

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 AcceptorCompletionAdviceResponseV06 implementation follows a specific implementaiton pattern. First of all, AcceptorCompletionAdviceResponseV06 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCompletionAdviceResponseV06Document implements IOuterDocument. Because AcceptorCompletionAdviceResponseV06 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCompletionAdviceResponseV06.

classDiagram
    class IOuterRecord
    AcceptorCompletionAdviceResponseV06 --|> IOuterRecord : Implements
    AcceptorCompletionAdviceResponseV06Document --|> IOuterDocument~AcceptorCompletionAdviceResponseV06~ : Implements
    class IOuterDocument~AcceptorCompletionAdviceResponseV06~ {
        AcceptorCompletionAdviceResponseV06 Message
     }

Document wrapper for serialization

The only real purpose AcceptorCompletionAdviceResponseV06Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.004.001.06’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCompletionAdviceResponseV06.ToDocument() method. The returned AcceptorCompletionAdviceResponseV06Document 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.004.001.06">

        <Hdr>
