Geofencing API for last-mile delivery in Brazil

Brazil's delivery and quick-commerce platforms operate across some of the most varied urban geography in Latin America — dense vertical neighborhoods in São Paulo, sprawling metro regions, and everything in between. A geofencing layer here needs to handle both tight urban precision and wide-area coverage without switching tools between the two.

Fencemaker supports both polygon and radius-based zone definitions for exactly that reason. Define a delivery zone matching real building or district boundaries, and a webhook fires the moment a tracked device enters, exits, or dwells in it.

Why this matters for Brazilian delivery operations

Mixed urban geography needs flexible zone types. A single delivery platform in Brazil might need tight polygon zones for São Paulo apartment towers and simpler radius zones for lower-density outlying regions — Fencemaker handles both from the same system rather than forcing a choice.

LGPD compliance is an active requirement, not a future one. Brazil's Lei Geral de Proteção de Dados governs how location and personal data get handled, with real enforcement behind it. Self-hosted deployment means data retention and processing policy stay under your direct control.

How the trigger flow works

POST https://your-app.com/webhooks/fencemaker
{
  "event": "geofence.enter",
  "zone_id": "zone_pinheiros_hub",
  "device_id": "entregador_4471",
  "timestamp": "2026-08-18T12:58:16Z",
  "coordinates": { "lat": -23.5629, "lng": -46.6817 }
}

Route that event to Slack for ops visibility, Telegram for delivery-partner alerts, or directly into your dispatch or fulfillment platform.

What you get out of the box

• Support for both polygon and radius-based zone definitions, matching dense urban and wide-area delivery regions 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 for LGPD compliance
• 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.
