EUDI Wallet integration for SaaS products and digital services

Treat EUDI as infrastructure, not as one login button

A production EUDI integration affects more than the screen where a user scans a QR code or approves a request. The product needs a controlled way to create presentation requests, validate wallet responses, map verified attributes into business logic and preserve enough operational context for support and audit.

For SaaS products, tenant isolation matters from the start. Each customer organisation can have a different relying-party identity, intended use, requested data and policy, while the protocol implementation itself should remain shared.

A stable verifier boundary protects the core product

Adminyra designs the integration so product code talks to a clear internal API rather than directly to every evolving wallet protocol detail. That keeps changes in OpenID4VP profiles, registration information or certificate handling contained in one infrastructure layer.

The business application can then consume a small set of outcomes such as verified identity attributes, failed verification, user cancellation or policy mismatch.

• Separate tenant configuration from shared verifier code.
• Model requested attributes explicitly per use case.
• Keep protocol responses out of ordinary product data where possible.
• Expose structured result states to the calling product.
• Design observability and audit events before production rollout.

Registration and intended use belong in the integration model

European rules require wallet relying parties to register and describe their intended use, including the data they intend to request. The 2026 amendments also strengthen the role of relying-party registration certificates and overasking checks.

That means the integration should make registered intended use and requested attributes visible operational configuration, not hidden constants inside frontend code.

What Adminyra can build around the wallet flow

An engagement can cover the verifier boundary, tenant configuration model, API integration into the existing SaaS product, error states, attribute mapping and the operational dashboard needed to manage relying-party context.

Adminyra EUDI is itself being developed around a multi-tenant verifier and control-plane model. Public claims remain limited to architecture and capabilities that are actually being designed or implemented.
