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. 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.
