# ISO 20022 Refinement Workstream

This workstream focusses on refining the ISO 20022 implementation released with Mojaloop V17.0.0 based on the experiences of adopters. This includes any refinements to the ISO 20022 messages defined in the Market Practice Document (MPD), and updates to the MPD itself.

# Business Justification

ISO 20022 is rapidly becoming the global standard for payment-system messaging, and Mojaloop’s ISO 20022 IIPS message standards, including Agreement of Terms (AoT), align with this global shift. However, the details re not yet finalised, and further refinement may well be likely.

# Latest Update (Summary)

The ISO 20022 workstream remains in a holding pattern while awaiting formal evaluation of Mojaloop’s proposed new messages, despite having addressed all previously requested changes. At the same time, recent discussions within the standards community have highlighted broader gaps in ISO 20022’s support for APIs and process definitions, creating a potential opportunity for Mojaloop to contribute to future API-related standardisation work.
