API Integration Guide (Getting Started)

  1. Provide target app name (here: FamApp) and required capabilities (e.g., transaction stream, transfers, gift card validation).
  2. We perform protocol analysis (OAuth/token flow, session persistence, SDK reverse points) and deliver secure implementation guidance.
  3. Deliver sample server implementation (with token refresh, retry strategy, pagination).
  4. Deliver documentation, Postman collection and local deployment instructions; assist with API gateway and security policy deployment where needed.

Common Access & Authentication

  • Authorization: Bearer token, session tokens, and device fingerprint/device tokens
  • Sensitive operations: additional signatures, PIN validation (card actions, transfers)
  • Data export: support CSV / Excel / JSON, with scheduled pulls
  • Security: TLS 1.2/1.3, least-privilege access, auditing logs

Compliance & Privacy

All work is performed under customer authorization or via publicly available / licensed data sources. We provide privacy-preserving guidance, minimal data retention suggestions, and optional NDA for compliance assessments.
