AuthorisationResponseV02

cain.002.001.02

The AuthorisationResponse message is sent by an issuer or an agent to an acquirer in response to an AuthorisationInitiation message.

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 AuthorisationResponseV02 implementation follows a specific implementaiton pattern. First of all, AuthorisationResponseV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AuthorisationResponseV02Document implements IOuterDocument. Because AuthorisationResponseV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AuthorisationResponseV02.

classDiagram
    class IOuterRecord
    AuthorisationResponseV02 --|> IOuterRecord : Implements
    AuthorisationResponseV02Document --|> IOuterDocument~AuthorisationResponseV02~ : Implements
    class IOuterDocument~AuthorisationResponseV02~ {
        AuthorisationResponseV02 Message
     }
  

Document wrapper for serialization

The only real purpose AuthorisationResponseV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:cain.002.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AuthorisationResponseV02.ToDocument() method. The returned AuthorisationResponseV02Document value will serialize correctly according to ISO 20022 standards.
