Stage 5 Report

Stage 5 Completion Report

Implemented

• Production-safe exception handling and request IDs.
• Security headers and stronger Apache access rules.
• DB-backed rate limiting with stricter auth, OTP, PIN, webhook, and public endpoint policies.
• Admin control center endpoints for dashboard, users, wallets, transactions, system logs, jobs, fraud rules, reversals, and observability.
• Granular roles and permissions tables with default seed data.
• Configurable fraud rules and fraud rule hit tracking.
• Reversal request workflow with compensating ledger entries.
• Request, error, latency, slow query, and rate-limit tables.
• Deployment, scaling, backup, security, admin, fraud, reversal, and observability docs.
• Postman collection and deployment/cron scripts.

Tables Added

roles, permissions, role_permissions, user_roles, admin_action_confirmations, fraud_rules, fraud_rule_hits, reversal_requests, request_logs, error_logs, api_latency_logs, slow_query_logs, rate_limit_attempts, system_settings.

Known Limitations

• Real provider integrations still need PSP/bank/GhIPSS credentials, certification, and sandbox testing.
• Admin OTP/2FA is issued as a placeholder signal; enforcement policy should be tightened before broad production access.
• Database-backed queue and rate limiting are suitable for pilot scale, but should move to dedicated infrastructure at higher volume.
• Regulatory, compliance, penetration testing, and security review are still required.

Next Recommended Stage

Stage 6 should focus on pilot readiness: real PSP sandbox integration, merchant/customer pilot scripts, compliance review artifacts, operational runbooks, and controlled user acceptance testing.

SikaaHub API is now suitable for internal testing and controlled pilot onboarding, but it is not yet production-certified.
