Geofencing API for last-mile delivery in the Philippines

Delivery operations across Metro Manila and other Philippine urban centers cover sprawling territory with traffic patterns that make ETA prediction genuinely hard. In that environment, knowing precisely when a rider enters or exits a delivery zone — rather than approximating it from a periodic location ping — is what keeps ops visibility accurate.

Fencemaker provides that as a dedicated trigger layer. Define zones as polygons matching real barangay or delivery-district boundaries, and a webhook fires the instant a tracked device crosses one.

Why this matters for Philippine delivery operations

Sprawl changes the geofencing problem. Philippine delivery territories often combine dense urban cores with long service radii, meaning a single delivery platform needs both tight polygon precision in city centers and workable radius-based zones for outlying areas — Fencemaker supports both without forcing a single approach.

Data privacy obligations are established and active. Under the Data Privacy Act of 2012 and National Privacy Commission oversight, location data handling carries real compliance weight. 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.exit",
  "zone_id": "zone_makati_cbd",
  "device_id": "rider_6603",
  "timestamp": "2026-08-18T15:41:29Z",
  "coordinates": { "lat": 14.5547, "lng": 121.0244 }
}

Route that event to Slack for live ops visibility, Telegram for rider-facing alerts, or directly into your delivery-tracking system.

What you get out of the box

• Support for both polygon and radius-based zone definitions, matching dense urban cores and sprawling outer delivery areas alike
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging stalled or delayed deliveries
• Self-hosted deployment, keeping location data under your direct control
• An ops portal for managing zones without engineering involvement

If your delivery footprint spans both dense city centers and wide-radius outlying areas, Fencemaker is built to handle that mix without requiring separate tooling for each.
