Why the digital euro is also an API topic
November 2026. Based on the ECB's July 2026 rulebook progress report and draft rulebook v0.91. Issuance depends on the EU regulation, and the rulebook may still change.
The digital euro is usually discussed as monetary policy. For payment service providers, it is also an integration project.
Interfaces
The back-end specifications cover messages between PSPs and the Eurosystem platform, including onboarding, lifecycle, alias lookups and settlement. The aim is harmonised APIs and data definitions aligned with ISO 20022.
Standards
The ECB has signed agreements with ECPC, nexo and the Berlin Group. Teams that know these standards from cards, terminals and Open Banking can build on that knowledge.
Beyond the API
PSPs also need to cover apps, wallets, merchant acceptance, front-end certification and customer onboarding. That takes coordination across product, payments, IT and operations.
A practical first step is to compare existing account, payment and alias processes with the draft specifications and identify what can be reused.
