Geofencing API for last-mile delivery in Indonesia

Indonesia's delivery and gig-economy platforms operate at a scale that stresses most geofencing setups fast — dense urban kampung layouts, sprawling metro areas like Jakarta and Surabaya, and rider fleets generating a high volume of location events continuously. A geofencing layer that works at a demo scale but chokes at real rider-fleet volume isn't actually usable here.

Fencemaker is built around continuous zone monitoring rather than periodic polling, so it holds up at the event volume Indonesian delivery platforms actually generate. Define delivery zones as polygons, and a webhook fires the moment a tracked device enters, exits, or dwells.

Why this matters for Indonesian delivery operations

Volume is the real test. Gig-delivery networks in Indonesia produce a large number of zone-crossing events per rider per shift across a large fleet. Fencemaker's engine watches continuously and pushes events only when something happens, avoiding the tradeoff between polling frequency and missed events that a naive polling setup forces.

Regulatory groundwork is shifting. With Indonesia's UU PDP data protection law establishing clearer expectations around personal data handling, self-hosted deployment gives delivery platforms a straightforward way to keep location data under direct control rather than a third-party vendor's terms.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_kemang_hub",
  "device_id": "rider_9042",
  "timestamp": "2026-08-18T08:12:07Z",
  "coordinates": { "lat": -6.2607, "lng": 106.8133 }
}

Route that event to Slack for ops visibility, Telegram for rider-facing alerts, or straight into your dispatch system.

What you get out of the box

• Polygon-based zone definitions built to handle dense, irregular urban layouts
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging stalled deliveries at scale
• Self-hosted deployment, keeping location data under your control
• An ops portal for managing zones without engineering involvement

If your current geofencing setup starts dropping events or lagging as rider-fleet volume grows, Fencemaker is built for exactly the volume Indonesian delivery platforms operate at.
