iGrant.io issuer backend (OpenID4VCI)

When to use

Build or extend the server that an issuer frontend talks to. It composes three building blocks for the issuance flow only (least privilege): igrantio-backend-proxy + igrantio-backend-webhooks + igrantio-backend-sse. For the verifier equivalent use igrantio-verifier-backend (separate skill). Read igrantio-ows-overview first for the API and architecture.

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.
