ATMWithdrawalRequestV01

catp.001.001.01

The ATMWithdrawalRequest message is sent by an ATM to an acquirer or its agent to request the approval of a withdrawal transaction at an ATM.

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.

Header building block

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the ATMWithdrawalRequestV01 implementation follows a specific implementaiton pattern. First of all, ATMWithdrawalRequestV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, ATMWithdrawalRequestV01Document implements IOuterDocument. Because ATMWithdrawalRequestV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type ATMWithdrawalRequestV01.

classDiagram
    class IOuterRecord
    ATMWithdrawalRequestV01 --|> IOuterRecord : Implements
    ATMWithdrawalRequestV01Document --|> IOuterDocument~ATMWithdrawalRequestV01~ : Implements
    class IOuterDocument~ATMWithdrawalRequestV01~ {
        ATMWithdrawalRequestV01 Message
     }
  

Document wrapper for serialization

The only real purpose ATMWithdrawalRequestV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:catp.001.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using ATMWithdrawalRequestV01.ToDocument() method. The returned ATMWithdrawalRequestV01Document 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.

        <Hdr>
