Geofencing API for field service and fleet territory alerts in India

India's field-service and distribution networks — FMCG sales reps covering assigned territories, telecom technicians dispatched across service zones, fleet vehicles moving between depots — run on a coordination problem that's fundamentally about zones, not just points on a map. Knowing when a rep enters their assigned territory, or when a vehicle strays outside its route, is the signal that keeps large distributed teams accountable without constant manual check-ins.

Fencemaker handles that as a dedicated trigger layer. Define territory or zone boundaries as polygons, and a webhook fires the instant a tracked device enters, exits, or dwells.

Why this matters for Indian field-service operations

Distributed rep networks need reliable, low-touch tracking. India's FMCG and telecom sectors run field forces numbering in the thousands, often across territories with overlapping or ambiguous boundaries. Precise polygon zones remove the ambiguity a radius-based approach would introduce.

Data control matters at fleet scale. With large volumes of location data generated daily across a distributed workforce, self-hosted deployment means that data — and its retention policy — stays on infrastructure you control.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_rep_territory_south_delhi",
  "device_id": "rep_2281",
  "timestamp": "2026-08-18T09:10:00Z",
  "coordinates": { "lat": 28.5245, "lng": 77.2066 }
}

Route the event to Slack, Telegram, or directly into your field-ops or CRM system.

What you get out of the box

• Polygon-based territory definitions for precise, unambiguous coverage
• Native Slack and Telegram webhook delivery
• Dwell-time detection for flagging reps or vehicles stalled unexpectedly
• Self-hosted deployment, keeping location data under your control
• An ops portal for defining and adjusting territories without engineering involvement

If your field team currently relies on manual check-ins or a generic mapping SDK bolted onto a CRM, Fencemaker replaces that with infrastructure built specifically for territory-based accountability.
