Geofencing API for field service and fleet territory alerts in Singapore

Field-service and facilities-management operations in Singapore work across a mix of high-rise commercial buildings, HDB residential estates, and industrial zones — each requiring precise territory boundaries rather than approximate coverage. As Singapore-based service companies extend operations regionally, the same territory-tracking infrastructure often needs to anchor field teams across the wider Southeast Asian footprint too.

Fencemaker provides that as a dedicated trigger layer. Define territory zones as polygons matching real building or district boundaries, and a webhook fires the instant a tracked device enters, exits, or dwells.

Why this matters for Singapore-based field-service operations

Vertical and mixed-use density need precise boundaries. High-rise commercial and HDB residential zones sit close together — polygon-based territories avoid the false triggers a radius approach produces in that density.

PDPA compliance applies directly to field-team tracking. Singapore's Personal Data Protection Act governs how employee location data gets handled. Self-hosted deployment keeps retention and processing decisions under your direct control.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_service_area_raffles_place",
  "device_id": "tech_1187",
  "timestamp": "2026-08-18T09:15:00Z",
  "coordinates": { "lat": 1.2839, "lng": 103.8515 }
}

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

What you get out of the box

• Polygon-based territory definitions for precise coverage of high-rise and mixed-use areas
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging jobs running long
• Self-hosted deployment, keeping location data under your control for PDPA compliance
• An ops portal for managing territories without engineering involvement

If Singapore is your operational base for a wider regional field-service footprint, Fencemaker's geofencing layer is built to scale with that ambition.
