API Integration Guide (Quick Start)

  1. Define target scenarios: merchant acquiring, cash-out, transaction export, or all-in-one integration.
  2. Obtain authorization & scopes: user consent, access tokens, refresh handling.
  3. Stable callbacks: idempotent webhook endpoints with retries for status updates.
  4. Reconciliation & consistency: nightly reconciliation, raw streams mapped to local ledger.
  5. Compliance & limits: KYC, data residency, and regional rules per jurisdiction.

Security & Compliance

  • End-to-end TLS, encryption at rest for sensitive fields
  • Least privilege (RBAC) and granular API scopes
  • Consent records & audit logs retained
  • Compliance with local data residency and regulatory requirements
  • We use terms like protocol analysis / reverse engineering within client authorization scope
