EUDI Wallet integration

Turn EUDI Wallet support into an application feature, not a separate infrastructure project.

A production EUDI Wallet integration spans more than a QR code. Software teams need to identify the relying party, define the intended use, request only the required attributes, integrate a verifier, handle same-device and cross-device journeys and prepare the production trust layer.

01

Start with the relying party and the business purpose

Before selecting endpoints or SDKs, determine which legal entity is actually requesting wallet information and why. The European Digital Identity framework requires wallet-relying parties providing digital services to register and to state their intended use, including the data they plan to request.

That makes the verification policy a business and compliance boundary as well as a technical configuration object. Adminyra models those policies separately so applications can use an approved request instead of assembling arbitrary claims at runtime.

02

Keep the wallet protocol behind a verifier boundary

Remote wallet presentations use a verifier-side protocol flow. The official EUDI reference verifier implements OpenID4VP and exposes separate APIs for the relying-party application and wallet interaction.

Adminyra keeps that protocol layer behind a stable application API. The calling SaaS product works with concepts such as relying party, policy, verification session, status and webhook while the verifier core can evolve as the ecosystem changes.

03

Use sandbox and production as genuinely different environments

Sandbox integration should prove the user journey, tenant routing, policy model and callback handling without pretending that test trust material is production identity infrastructure.

Production rollout then adds the national registration, certificates, trusted issuer validation, monitoring and key-management controls required by the real ecosystem. Separating those environments early prevents test shortcuts from becoming production architecture.

FAQ

Questions teams ask before integrating EUDI Wallets

What is required for an EUDI Wallet integration?

A complete integration typically combines the relying-party role and registration, a verifier or verifier service, an OpenID4VP presentation flow, trust validation, data-minimised policies and the application's own business workflow.

Should our SaaS product implement the wallet protocol directly?

It can, but a verifier boundary reduces coupling. A stable API lets the product keep its normal business model while protocol, certificates and trust infrastructure are managed separately.

Can we start before production wallets are widely available?

Yes. The EUDI reference implementations and national sandbox initiatives are specifically useful for integration and interoperability testing before broad production rollout.
