ISO 20022 Whitepapers

This section provides access to a growing collection of whitepapers that support the implementation and evolution of ISO 20022. 

As the adoption of ISO 20022 continues to grow across financial services, the need for consistent, interoperable API design becomes increasingly important. To support this evolution, a series of whitepapers have been developed to guide implementers in aligning API development with ISO 20022 standards and data semantics.

These whitepapers provide practical insights into transforming ISO 20022 message definitions into JSON Schema and offer best practices for designing APIs that are both standards-compliant and implementation-ready. Whether you're exploring JSON as an alternative syntax or building APIs within an ISO 20022-based ecosystem, these resources are designed to help you navigate the journey.

You can download the current and archived whitepapers  hereunder.
