Auth Enforcement

Scope

This BFF enforces authenticated access on business endpoints using Thalos session validation.

Protected Endpoints

  • /api/pos/transactions/summary
  • /api/pos/transactions/recent-payments
  • /api/pos/transactions/{transactionId}
  • /api/pos/transactions/payments

Anonymous Endpoints

  • /health
  • /healthz

Session Validation Contract

  • BFF requires at least one session cookie:
    • thalos_session
    • thalos_refresh
  • BFF calls Thalos session introspection endpoint:
    • GET /api/identity/session/me
  • Base address configured by:
    • ThalosAuth:BaseAddress

Error Semantics

Standard auth error payload:

{
  "code": "unauthorized|forbidden|session_missing|session_invalid",
  "message": "human-readable message",
  "correlationId": "request correlation id"
}
  • 401: missing or invalid session
  • 403: permission denied by identity service
  • 503: identity service unavailable or timeout (identity_unavailable|identity_timeout)

Correlation

  • Incoming/outgoing correlation header: x-correlation-id
  • Correlation ID is forwarded to Thalos session validation call.

Validation Rule

  • Successful session introspection must also include isAuthenticated=true in Thalos response payload.
