Geofencing API for last-mile delivery in Poland

Poland has become one of Central and Eastern Europe's fastest-growing e-commerce and logistics markets, with parcel-locker networks like InPost and courier platforms like DPD Poland setting the pace for the wider region. That growth means delivery volume — and the number of zone-crossing events a geofencing layer needs to handle — keeps climbing.

Fencemaker is built for that kind of continuous, high-volume trigger detection. Define delivery zones as polygons matching real district or locker-network boundaries, and a webhook fires the instant a tracked device enters, exits, or dwells.

Why this matters for Polish delivery operations

Parcel-locker density changes the geofencing problem. Networks built around dense locker placement need tight zone precision to distinguish between adjacent locker locations — radius-based approximation isn't accurate enough at that density.

UODO (Poland's data protection authority) oversight is active. Location data handling falls under the same GDPR framework as the rest of the EU, with Polish enforcement specifically. Self-hosted deployment keeps retention and processing decisions under your control.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_warsaw_mokotow_locker_12",
  "device_id": "kurier_3387",
  "timestamp": "2026-08-18T09:55:40Z",
  "coordinates": { "lat": 52.1942, "lng": 21.0122 }
}

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

What you get out of the box

• Polygon-based zone definitions precise enough for dense locker-network layouts
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging delayed pickups or handoffs
• Self-hosted deployment, keeping location data under your control
• An ops portal for managing zones without engineering involvement

If your delivery platform is scaling alongside Poland's e-commerce growth, Fencemaker's geofencing layer is built to keep up with that volume rather than becoming the bottleneck.
