Cloud API sends webhook → POST /api/webhooks/biometric-logs 2. System validates signature + data 3. BiometricLog created (status: pending) 4. Job queued for async processing 5. Return 202 immediately to cloud 6. Background worker processes job 7. Data inserted into local database 8. Status updated to success/failed 9. Event fired for extensions 10. Log visible in dashboard & queries ================================================================================ API ENDPOINTS CREATED ================================================================================ WEBHOOK (Receives biometric events from cloud) POST /api/webhooks/biometric-logs Headers: X-Webhook-Signature, X-Webhook-Timestamp HEALTH CHECK (Monitor system status) GET /api/webhooks/biometric-logs/health RETRY FAILED (Manually retry failed logs) POST /api/webhooks/biometric-logs/retry?limit=10&max_retries=3 ================================================================================ CLI COMMANDS AVAILABLE ================================================================================ php artisan biometric:sync --pull Pull logs from cloud API php artisan biometric:sync --push Push local logs to cloud php artisan biometric:sync --retry Retry failed logs php artisan biometric:sync --cleanup Clean old logs (requires confirmation) php artisan biometric:sync --all Run all operations php artisan biometric:sync Show statistics ================================================================================ SECURITY FEATURES ================================================================================ ✅ HMAC-SHA256 webhook signature verification ✅ Replay attack prevention (10-minute timestamp window) ✅ Input validation and sanitization ✅ Idempotency (no duplicate logs) ✅ Rate limiting (60 req/min) ✅ Error logging & audit trail ✅ Automatic retry with backoff ================================================================================ NEXT STEPS (RECOMMENDED) ================================================================================ IMMEDIATE (Day 1): 1. Read: BIOMETRIC_QUICK_START.md 2. Configure: .env variables 3. Test: Health endpoint 4. Verify: Database table created SHORT TERM (Week 1): 1. Deploy: Queue worker 2. Monitor: Health endpoint 3. Test: With real cloud API 4. Validate: Logs appearing in database MEDIUM TERM (Month 1): 1. Create: Filament UI resource 2. Setup: Scheduler for polling 3. Implement: Notifications 4. Monitor: Performance metrics LONG TERM (Ongoing): 1. Analytics: Reporting dashboard 2. Export: CSV/Excel functionality 3. Optimization: Performance tuning 4. Extensions: Custom event listeners ================================================================================ MONITORING CHECKLIST ================================================================================ □ Queue worker is running □ Health endpoint returns healthy status □ No pending logs stuck for > 5 minutes □ Failed logs count is minimal □ New logs appearing in database □ No errors in storage/logs/laravel.log □ Cloud API webhook is configured ================================================================================ TROUBLESHOOTING QUICK REFERENCE ================================================================================ WEBHOOK NOT BEING CALLED: → Verify cloud API has correct webhook URL → Check firewall allows incoming HTTPS → Verify API key in cloud API settings LOGS NOT SYNCING: → Check queue worker is running: ps aux | grep queue:work → Check queue table: SELECT * FROM jobs; → Check logs: tail -f storage/logs/laravel.log SIGNATURE ERROR: → Verify BIOMETRIC_WEBHOOK_SECRET matches cloud API → Check timestamp is within 10 minutes HIGH MEMORY USAGE: → Reduce batch size → Add cleanup task to scheduler → Limit queue workers More details → See BIOMETRIC_QUICK_START.md ================================================================================ ENVIRONMENT VARIABLES ================================================================================ REQUIRED: BIOMETRIC_CLOUD_API_KEY= BIOMETRIC_WEBHOOK_SECRET= OPTIONAL (with defaults): BIOMETRIC_SYNC_ENABLED=true BIOMETRIC_API_ENDPOINT=https://api.cloud.example.com BIOMETRIC_POLL_INTERVAL=5 BIOMETRIC_MAX_LOG_AGE=30 BIOMETRIC_LOG_RETENTION_DAYS=90 See .env.biometric.example for template ================================================================================ PRODUCTION CHECKLIST ================================================================================ PRE-DEPLOYMENT: □ All .env variables configured □ Queue connection set to redis or database □ Database backups enabled □ Error logging configured □ Monitoring alerts set up DEPLOYMENT: □ Run migration: php artisan migrate □ Start queue worker (via supervisor) □ Test webhook endpoint □ Verify logs in database POST-DEPLOYMENT: □ Monitor health endpoint daily □ Check failed logs regularly □ Review error logs weekly □ Clean old logs scheduled ================================================================================ SUPPORT & DOCS ================================================================================ Questions about...
