Geofencing API for last-mile delivery in Singapore

Singapore's position as a logistics and distribution hub for Southeast Asia means delivery platforms based here often aren't just serving the local market — they're running the infrastructure that regional operations get built on. That raises the bar for the trigger layer underneath geofencing: it needs to be reliable enough to anchor delivery operations across the wider region, not just handle Singapore's own high-rise residential density.

Fencemaker provides that layer directly. Define delivery zones as polygons matching HDB blocks, condo compounds, or commercial districts, and a webhook fires the instant a tracked device enters, exits, or dwells in a zone.

Why this matters for Singapore-based delivery operations

Vertical density changes the geofencing problem. High-rise residential delivery means zone boundaries often need to account for building footprints precisely, not approximate radii that bleed into neighboring blocks.

PDPA compliance is a live operational concern. Singapore's Personal Data Protection Act governs how location and delivery data get collected and retained. Self-hosted deployment means retention policy and data handling stay under your direct control, which simplifies compliance conversations considerably.

How the trigger flow works

{
  "event": "geofence.enter",
  "zone_id": "zone_tampines_block_512",
  "device_id": "rider_1187",
  "timestamp": "2026-08-18T10:30:52Z",
  "coordinates": { "lat": 1.3496, "lng": 103.9568 }
}

Route that event to Slack for ops visibility, Telegram for rider alerts, or directly into your dispatch or fulfillment system.

What you get out of the box

• Polygon-based zone definitions for accurate coverage of high-rise residential and commercial delivery areas
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging stalled deliveries
• Self-hosted deployment, keeping location data under your direct control for PDPA compliance
• An ops portal for managing zones without engineering involvement

If Singapore is your operational base for a wider Southeast Asian delivery footprint, Fencemaker's self-hosted geofencing layer is built to scale with that regional ambition rather than being a local-only fix.
