API Integration & Security Considerations
Authentication: Prefer OAuth2 / JWT or certificate-based mutual TLS (mTLS).
Device registration: Implement device binding (Cadastro de Dispositivo) and device identity verification.
Least privilege: Request FGTS data strictly under user consent.
Sensitive data handling: Documents uploaded/stored should be end-to-end encrypted; retain consent records and access logs.
Compliance: Adhere to LGPD (or local privacy laws), and the access policies of fiscal/social departments.
