igrantio-verifier-backendlisted

Build the backend for an OpenID4VP + DCQL credential VERIFIER / relying party against the iGrant.io Organisation Wallet Suite (OWS). A tenant-aware Node/TypeScript (Express) service that hides per-organisation API keys behind a proxy, registers and receives OWS verification webhooks (HMAC-verified), and pushes the verified result to the browser over SSE. Use when an application must request and verify a credential presentation from an eIDAS 2.0 EUDI Wallet (EUDIW) or European Business Wallet (EUBW) and the API key must never reach the frontend. Supports wallet-signed transaction data (SCA payments, e-mandates, login/risk authentication, account access, QES document signing).

# iGrant.io verifier backend (OpenID4VP + DCQL) ## When to use Build or extend the server that a **verifier / relying-party** frontend talks to. It composes `igrantio-backend-proxy` + `igrantio-backend-webhooks` + `igrantio-backend-sse` for the verification flow only (least privilege). For the issuer equivalent use `igrantio-issuer-backend` (separate skill). Read `igrantio-ows-overview` first. ## Prerequisites - An **iGrant.io Organisation Wallet Suite (OWS) API key**. Get it from [support@igrant.io](mailto:support@igrant.io). Keep it on the server, in an environment variable or a secret manager. The browser never sees it. - The **OWS environment** the key belongs to. The default is **demo** (`https://demo-api.igrant.io`). Use **staging** (`https://staging-api.igrant.io`) only when the integrator asks for it. A key works only in its own environment. ## Ask the integrator first Ask one question at a time. Wait for the answer. Give the recommended default with each question. Look up facts in the project (framework, environment variables, an existing backend) instead of asking for them. Record the answers before you write code. 1. **Environment** - demo or staging? _Default demo (`https://demo-api.igrant.io`); a switch later is a configuration change._ 2. **API key** - do you have the OWS API key for that environment? If not, request it from [support@igrant.io](mailto:support@igrant.io) before you continue. 3. **Tenancy** - one organisation, or several
