What is it?
ISO 20022ย is a multi-part International Standard prepared by ISO Technical Committee TC68 Financial Services. It describes a common platform for the development of messages using:
a modelling methodology to capture in a syntax-independent way financial business areas, business transactions and associated message flows.
a central dictionary of business items used in financial communications
a set of XML and ASN.1 design rules to convert the message models into XML or ASN.1 schemas, whenever the use of the ISO 20022 XML or ASN.1-based syntax is preferred
Of particular concern for Actio is the modelling of business transactions (between users of Actio client platforms and the Actio platform itself) and associated message flows (external and internal to the Actio platform).
Why do we need it?
Our expectation is that we would benefit from the implementation of ISO20022 in two significant ways:
Because it is an International Standard (not my capitalisationโฆ), we expect to see an increase in the adoption of the standard by companies and platforms that might want to use Actio for Financial Crime Risk Management services associated with their business transactions. If our interfaces and internal messaging is already ISO20022 compliant, integration with these platforms is generally expected to be easier.
More directly, the emerging popularity of ISO20022 in Financial Services has created something of an atmosphere of FOMO amongst financial services companies and even though many companies themselves are not yet ISO20022 compliant in the modelling of their business transactions and associated message flows, these companies are increasingly more loathe to even consider introducing new ISO20022 non-compliant products into their eco-systems. For viability and desirability of Actio as a long-term Financial Crime Risk Management solution, ISO20022 compliance has become essential.
As an OC platform that we are building from scratch (with the help of many open-source products), we have a unique opportunity to build ISO20022 compliance into the design from the beginning.
What does ISO20022 compliance mean?
ISO20022 compliance is not only about the formatting of messages into, within and out of the Actio platform, but also relates to:
the terminology that we use to describe business concepts, message concepts and data types, and
the communication and interaction requirements in and between various Business Areas.
While Actio itself does not necessarily have any Business Areas, Actio is expected to be implemented in complex business environments with varied and distributed business operations.
ISO20022 is split into 3 main building blocks:
The data model, which is referred to as the ISO20022 Business Model
The data dictionary, known as the ISO20022 Repository
Messaging definition reports
From the perspective of the 3 main building blocks of ISO20022, the impact on Actio can be broadly described as follows:
Business Model
The business model covered a number of business domains:
Domain | Description | Actio |
|---|---|---|
Common | The business components and their elements that are used to described the Business Concepts that are common to business domains. | MVP |
Securities | The Securities domain provides the business components and their elements for cash movements related to transactions on equities, fixed income and other securities industry related financial instruments. | ย |
Payments and Cash Management | The Payments domain provides the business components and their elements for all payment activities that relate to transfer of funds between parties. | MVP |
Trade Services | The Trade Services domain provides the business components and their elements related to all of the Trade Services operations that need to be reported in the statements. | ย |
Foreign Exchange | The Foreign Exchange domain provides the business components and their elements of all operations that are related to the foreign exchange market. Often abbreviated as FOREX. | ย |
Cards and Related Services | The Cards and Related Services domain provides the business components and their elements of all operations that are related to the following non-exhaustive list of financial instruments:
| ย |
There are currently several thousand different business concepts identified in the business model.
Data Dictionary
Painfully, you have to browse the data dictionary through search terms online or you have to download the e-repository in EMF format for plug it into the Eclipse Indigo SR2 IDE.
The data dictionary contains terms and definitions, as well as associated elements for each term. For example the Business Component โpartyโ is defined as follows:
ย
Each of the Business Components can be referenced in the Business Model where the components are placed in a simplified business information model represented in UML:
ย
The components that are then involved in a payment can be mapped as follows:
ย
Message Definition Reports
The Payments and Cash Management domain includes a number of specific Business Areas for which messages have been classified. The following Business Areas are likely to be relevant to the Actio platform, its operator or its clients.
Business Area | Code | Description | Actio |
|---|---|---|---|
Payments Initiation | pain | Messages that support the initiation of a payment from the ordering customer to a financial institution that services a cash account and reporting its status | MVP |
Payments Clearing and Settlement | pacs | Messages that support the clearing and settlement processes for payment transactions between financial institutions | MVP |
Cash Management | camt | Messages that support the reporting and advising of the cash side of any financial transactions, including cash movements, transactions and balances, plus any exceptions and investigations related to cash transactions. | ย |
Payments Remittance Advice | remt | Messages that support communication between creditors and debtors regarding remittance details associated with payments. | ย |
Account Management | acmt | Messages that support the management of account related activities, such as the opening and maintenance of an account. | ย |
Administration | admi | Generic messages, ie, system event notifications, generic rejections, etcโฆ | ย |
Authorities Financial | auth | Messages that support the provision of miscellaneous financial information to authorities, such as Regulators, Police, | ย |

Actio currently focuses on instant payments and funds transfers, but in the future may also include a wider variety of transaction types or lines of business. The scope of the ISO 20022 messages accommodated by Actio would have to be revisited when the variety increases.
Of particular future interest to Actio would be the messages related to the Fraud Reporting and Disposition Business Area; however these messages are currently related to the Card Payments and Related Transactions domain and are not suitable in a general context. It may be worth exploring the content of the Fraud Reporting messages to see if there is any benefit in using these as a template for the results reporting out of Actio.
Business Area: Fraud Reporting and Disposition
https://www.iso20022.org/business-area-message-set/366/881/download
Message ID | Description |
|---|---|
cafr.001.001.01 | A FraudReportingInitiation message is usually sent by a financial institution acting as an acquirer or as an issuer to an agent (processor, agent) to inform about a confirmed fraudulent transaction. |
cafr.002.001.01 | A FraudReportingResponse message is sent by an agent (processor, agent) to an issuer or acquirer in response to a FraudReportingInitiation message. |
cafr.003.001.01 | A FraudDispositionInitiation message is usually sent by an agent to a financial institution acting as an acquirer or as an issuer to report about the disposition of a confirmed fraudulent transaction. |
cafr.004.001.01 | A FraudDispositionResponse message is sent by an issuer or acquirer to an agent (processor, agent) in response to a FraudDispositionInitiation message. |
Within each of the Business Areas, there are several messages defined to meet specific business model/process requirements. The messages available for pacs and pain are listed below. Note the structure of each message:

Mapping Mojaloop to Actio
ย
Figure 1: PAIN and PACS in Mojaloop
In Mojaloop, the QUOTES messages are translated to pain.001 (POST) and pain.013 (PUT) and the TRANSFER messages are translated to pacs.008 (POST) and pacs.002 (PUT).
Our approach for mapping the data requirements for Actio, and specifically in relation to incoming Mojaloop data, is to:
Identify the Mojaloop data fields that are available to Actio as part of the QUOTE and TRANSFER messages
Group the Mojaloop data fields by ISO20022 business components, as defined in the ISO20022 data dictionary
Identify a suitable data element to represent the data in the Actio platform as an ISO20022 compliant element
Specify the transformation requirements for the Mojaloop field to the ISO20022 element
Identify additional minimum data fields required in the ISO20022 message that are not available in the Mojaloop messages and source suitable values for these fields.
Further work will be required to design a fully compliant ISO20022 data model for Actio that includes the data that we are intending to use for the Transaction Monitoring Service.
Mojaloop message analysis
Initial analysis of the current Mojaloop messages show the following:
The POST /quotes messages contains the most detailed information out of the all of the Mojaloop messages. Later messages do not repeat the information in the POST /quotes message. If later messages are to be evaluated effectively, they would need to be enriched with the data from earlier messages during Actio data preparation.
Not every Mojaloop implementation follows the quote-transfer pattern and some systems may be deployed without a quotes process. The transfers messages do not currently contain any identifying information for either the Payer (debtor) or the Payee (creditor) and without the preceding quotes messages, the Actio platform will not be able to reference this information for the transaction evaluation.
Not all of the data that is required for transaction evaluation is available from Mojaloop. The Actio team have taken the design decision that all data required for evaluation of a transaction would be supplied in the transaction message, and not through parallel enrichment. Privacy legislation such as GDPR constrains Actioโs ability to collect personal information for an unauthorised purpose and we would not be able to collect personal information on the expectation of a future transaction - we would only be able to collect personal information as part of the actual transaction.
The Mojaloop message provides an Extension List facility where additional data that does not fit natively withing the Mojaloop message can be supplied. It is recommended that the Extension List be used to supply additional information that is required for transaction evaluation, and also to supplement transfers messages in the absence of a quotes process.
The Mojaloop quotes messages do not have a direct equivalent in the ISO 20022 message schema. The ISO20022 messages are more concerned with the fulfilment of the payment, and not so much with the protocols and processes employed by a system to set up the circumstances for a payment, such as a quoting process. Mojaloop selected the Payment Initiation Business Area and specifically the pain.001 and pain.013 messages to represent the quotes messages and Actio has adopted this approach as well.
ISO20022: XML vs JSON
In ISO 20022, the most widely used syntax is eXtensible Mark-up Language (XML), while the preferred syntax in Actio interfaces and messaging to date has been JavaScript Object Notation (JSON). In reality, ISO20022 as a standard is syntax-neutral and the ISO20022 Technical Support Group has issued a best-practices white paper on to assist implementers to define RESTful Web Service APIs with resources represented in XML and/or JSON syntax.
