API Integration & Security Notes

1. Authentication: Prefer OAuth2 / JWT or certificate-based mutual TLS (mTLS).
2. Device Registration: Implement device binding (Cadastro de Dispositivo) and device identity verification.
3. Least Privilege: Request FGTS data with least privilege; only read within user consent.
4. Sensitive Data Handling: Upload/storage of documents should use end-to-end encryption; maintain consent records and access logs.
5. Compliance: LGPD or local privacy laws; interface access policies.
