Geofencing API for field service and fleet territory alerts in Germany

German field-service and fleet operations face a specific compliance reality: employee and vehicle location tracking is subject to some of the strictest data protection enforcement anywhere, and works councils (Betriebsrat) often have a direct say in how such tracking is implemented. That makes the infrastructure choice — not just the feature set — part of the compliance answer.

Fencemaker runs self-hosted, which means location data from field reps and fleet vehicles never leaves infrastructure you control. Define territory zones as polygons, and a webhook fires the instant a tracked device enters, exits, or dwells.

Why this matters for German field-service operations

GDPR and works-council requirements both shape tracking design. A self-hosted deployment gives you a direct answer to both regulatory and employee-representation questions about where data lives and how long it's retained — not a vendor's standard terms.

Precision matters for dense mixed-use territories. German service areas often mix residential, commercial, and industrial zones closely — polygon-based boundaries match that reality more accurately than a radius approximation.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.dwell",
  "zone_id": "zone_service_area_koeln_west",
  "device_id": "techniker_5502",
  "timestamp": "2026-08-18T14:30:00Z",
  "coordinates": { "lat": 50.9375, "lng": 6.9603 }
}

Route that event to Slack, Telegram, or directly into your field-service management system.

What you get out of the box

• Self-hosted deployment — location data stays on infrastructure you control
• Polygon-based territory definitions for precise coverage of mixed-use service areas
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging jobs running long
• An ops portal for managing territories without engineering involvement

For German field-service teams navigating both GDPR compliance and works-council expectations around tracking, self-hosted is the more defensible starting point — and Fencemaker is built to make that the easy option.
