Scope The AcceptorCompletionAdvice message is sent by a card acceptor to notify an acquirer about the completion and final outcome of a card payment transaction. The message can be sent directly to the acquirer or through an agent. Usage The AcceptorCompletionAdvice message is used either to:
- inform the acquirer about the successful end of a transaction;
- reverse a transaction which was not successfully completed (for example, cancellation of transaction by the cardholder), but where an authorisation had been previously given. The AcceptorCompletionAdvice message may also embed the information required for transferring to the acquirer all data needed to perform the financial settlement of the transaction (capture). Should the acquirer not receive a correct response to an AcceptorCompletionAdvice message; the card acceptor sends back an AcceptorCompletionAdvice message to the acquirer.
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

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 AcceptorCompletionAdviceV01 implementation follows a specific implementaiton pattern. First of all, AcceptorCompletionAdviceV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCompletionAdviceV01Document implements IOuterDocument. Because AcceptorCompletionAdviceV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCompletionAdviceV01.
classDiagram class IOuterRecord AcceptorCompletionAdviceV01 --|> IOuterRecord : Implements AcceptorCompletionAdviceV01Document --|> IOuterDocument~AcceptorCompletionAdviceV01~ : Implements class IOuterDocument~AcceptorCompletionAdviceV01~ { AcceptorCompletionAdviceV01 Message }
Document wrapper for serialization
The only real purpose AcceptorCompletionAdviceV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.003.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCompletionAdviceV01.ToDocument() method. The returned AcceptorCompletionAdviceV01Document value will serialize correctly according to ISO 20022 standards.
