AcceptorCompletionAdviceV08

caaa.003.001.08

The AcceptorCompletionAdvice message is sent by an acceptor (or its agent) to notify the acquirer (or its agent) of the outcome of the payment at the acceptor, and to transfer the financial data of the transaction to the acquirer (capture). A AcceptorCompletionAdvice message is also sent to reverse an approved authorisation and any associated financial transfer (capture), if the card payment transaction could not be completed successfully.

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 AcceptorCompletionAdviceV08 implementation follows a specific implementaiton pattern. First of all, AcceptorCompletionAdviceV08 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCompletionAdviceV08Document implements IOuterDocument. Because AcceptorCompletionAdviceV08 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCompletionAdviceV08.

classDiagram
    class IOuterRecord
    AcceptorCompletionAdviceV08 --|> IOuterRecord : Implements
    AcceptorCompletionAdviceV08Document --|> IOuterDocument~AcceptorCompletionAdviceV08~ : Implements
    class IOuterDocument~AcceptorCompletionAdviceV08~ {
        AcceptorCompletionAdviceV08 Message
     }

Document wrapper for serialization

The only real purpose AcceptorCompletionAdviceV08Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.003.001.08’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCompletionAdviceV08.ToDocument() method. The returned AcceptorCompletionAdviceV08Document 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.
