ISO 20022

ISO 20022 is the international financial messaging standard published by the International Organization for Standardization (ISO) that provides a common language and model for financial data. It defines business processes, data elements, and message definitions used by banks, payment systems, securities settlement systems, and other financial institutions worldwide for payment messages, securities messages, trade finance, and foreign exchange. SWIFT serves as the ISO 20022 Registration Authority, maintaining the message repository and e-Repository. As of 2025 ISO 20022 became the exclusive format for cross-border payments on the SWIFT network, with more than 60 central banks worldwide either completed or underway with migration.

ISO 20022 publishes 1 API on the APIs.io network: Message Catalogue API. Tagged areas include Financial Messaging, Payments, Securities, Banking, and ISO Standard.

ISO 20022’s developer surface includes documentation, getting-started guide, GitHub presence, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/iso20022: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
