Secure Next.js API Routes
Backend authorization must protect every route that returns sensitive data or changes state.
Checklist
- Authenticate the caller on the server.
- Check role or ownership before reading private records.
- Validate request bodies before writing data.
- Return
401for unauthenticated requests. - Return
403for authenticated users without permission. - Avoid exposing internal error details.
Platform Notes
The platform uses centralized authorization helpers in lib/authz.ts so admin checks are consistent across dashboards and API routes.
