AcceptorReconciliationRequestV01

caaa.009.001.01

Scope The AcceptorReconciliationRequest message is sent by the card acceptor to the acquirer or an agent to communicate the totals of the card payment transaction for a reconciliation period. An agent never forwards the message. Usage The AcceptorReconciliationRequest message is used to ensure that the debits and credits correspond to the balances computed by the acquirer or its agent for the same reconciliation period. The AcceptorReconciliationRequest message is also used to close a reconciliation period.

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

AcceptorReconciliationRequestV01 *-- "1..1" AcceptorReconciliationRequest1 : ReconciliationRequest

Now, we will zero-in one-by-one on each of these building blocks.

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AcceptorReconciliationRequestV01 implementation follows a specific implementaiton pattern. First of all, AcceptorReconciliationRequestV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorReconciliationRequestV01Document implements IOuterDocument. Because AcceptorReconciliationRequestV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorReconciliationRequestV01.

classDiagram
    class IOuterRecord
    AcceptorReconciliationRequestV01 --|> IOuterRecord : Implements
    AcceptorReconciliationRequestV01Document --|> IOuterDocument~AcceptorReconciliationRequestV01~ : Implements
    class IOuterDocument~AcceptorReconciliationRequestV01~ {
        AcceptorReconciliationRequestV01 Message
     }
  

Document wrapper for serialization

The only real purpose AcceptorReconciliationRequestV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.009.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorReconciliationRequestV01.ToDocument() method. The returned AcceptorReconciliationRequestV01Document value will serialize correctly according to ISO 20022 standards.
