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.

Before you build: run the integrator intake in igrantio-ows-overview - environment, API key, tenancy, backend host, webhooks, frontend - one question at a time, a recommended default with each.
