Geofencing API for last-mile delivery in the Netherlands

The Netherlands' position as a European distribution hub — anchored by Rotterdam's port and Schiphol's air-freight capacity — means Dutch delivery platforms often aren't just serving the domestic market, they're running the last-mile layer for goods moving across the wider EU. PostNL's parcel network and Thuisbezorgd-style delivery platforms both depend on precise zone-crossing detection to keep that layer reliable.

Fencemaker provides that trigger layer directly. Define delivery zones as polygons matching real neighborhood or distribution-district boundaries, and a webhook fires the instant a tracked device enters, exits, or dwells.

Why this matters for Dutch delivery operations

Hub-scale volume needs infrastructure built for it. A distribution hub processes zone-crossing events at a different scale than a purely domestic delivery operation — Fencemaker's engine watches continuously rather than relying on a polling interval that either lags or drops events under load.

Dutch DPA (Autoriteit Persoonsgegevens) enforcement is active. Location data handling carries real compliance weight here. Self-hosted deployment means retention and processing decisions stay under your direct control.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_rotterdam_distribution",
  "device_id": "bezorger_5510",
  "timestamp": "2026-08-18T08:45:30Z",
  "coordinates": { "lat": 51.9244, "lng": 4.4777 }
}

Route that event to Slack, Telegram, or directly into your dispatch or fulfillment system.

What you get out of the box

• Polygon-based zone definitions for precise coverage of hub and distribution areas
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging delayed handoffs at distribution points
• Self-hosted deployment, keeping location data under your control
• An ops portal for managing zones without engineering involvement

If the Netherlands is your operational base for a wider European distribution footprint, Fencemaker is built to scale with that role rather than being a local-only fix.
