Lexware Office Integration — Details

• Rate Limiter: In-Memory Token Bucket, 2 Requests/Sekunde (Lexware API Limit)
• Beleg-Caching: PostgreSQL-Tabelle lexware_vouchers, alle 4h Cron-Refresh + manueller Refresh
• ERP-Push: Companies/Contacts mit Tag "ERP" werden automatisch (30min Cron) + bei Update nach Lexware gepusht
• Distributed Locks: Redis SET NX EX verhindert Doppelausfuehrung von Cron-Jobs
• Optimistic Locking: lexwareContactVersion fuer sichere Updates
• Graceful Degradation: Ohne LEXWARE_API_KEY → Modul deaktiviert, Health = "unconfigured"

• Port: 3100
• Neue Env-Variablen: LEXWARE_API_KEY, LEXWARE_API_URL
• Traefik HTTP + HTTPS Routing: /api/v1/crm/*

Sicherheit

• Token-Revocation via Redis
• Multi-Tenancy: Alle Queries filtern nach tenantId
• Globaler ValidationPipe (whitelist + forbidNonWhitelisted)
• Strict TypeScript, kein any
