eFinTech — FDX recipient app

The fintech side of open banking: a registered FDX data recipient consuming consented provider data. This app demonstrates the full recipient flow — client registration, consent initiation, callback activation, and consented reads through Bank8:FDX.

What it demonstrates​

  • Recipient registry bookkeeping — the fintech's own view of its customers' consents (provider, scopes, selected accounts, PKCE verifier, token references, status).
  • OAuth as the only inter-org contract — the recipient never reads the provider's database; it calls consent-scoped APIs and honors the provider's authorization server.
  • Data minimization in practice — reads surface only what the consent covers (CSDF-filtered by the provider).
