🏗️ Technical Architecture

License Data Flow

User Request → WHOOSH Frontend → WHOOSH Backend → KACHING API → License Data
           ← UI Components    ← Proxy Endpoints ← Service Auth ← 

Security Layers

1. Frontend: UX enhancement and visual feedback only
2. Backend Proxy: Secure license ID resolution and API calls
3. KACHING Integration: Service-to-service authentication
4. License Authority: Centralized license validation and enforcement

Caching Strategy

• Frontend Cache: 30s-10min TTL based on data volatility
• License Status: 1 minute TTL for balance of freshness/performance
• Feature Availability: 5 minute TTL (stable data)
• Quota Usage: 30 second TTL for real-time monitoring
• Tier Information: 1 hour TTL (static configuration data)
