API Integration Quick Guide

1. Provide target app name and clear use cases (e.g., balance sync, exports, payments).
2. We perform protocol analysis (2-5 business days) with authorization flow capture.
3. Deliver API design and sample implementations (3-8 business days).
4. Provide test plans, scripts and deployment guidance.
5. Go-live support and optional SLA for ongoing maintenance.

Security & Compliance

All integrations are based on authorized access or public APIs. We advocate data minimization, TLS, and auditable logging. Optional security assessments and NDA available. Reverse engineering is described here as compliant protocol analysis where permitted by law.
