Offline DIGIPIN Microservice API for Precise India Location Mapping

This n8n workflow creates a lightweight, self-hosted HTTP microservice API for DIGIPIN, India's 10-character digital pincode system that uniquely identifies any 3x3 meter square nationwide. Ideal for areas with inconsistent physical addresses, it enables precise location mapping for homes, shops, landmarks, and more without relying on external APIs or services.

The workflow exposes two simple GET endpoints: /generate-digipin?lat={lat}&lon={lon} to encode GPS coordinates into a DIGIPIN, and /decode-digipin?digipin={code} to retrieve lat/lon from a DIGIPIN. Powered entirely by JavaScript in an n8n Function node, it processes requests via an HTTP Webhook trigger and returns JSON responses instantly.

Benefits include complete offline operation, no API keys or internet dependency, high speed, and easy extensibility. Integrate it with forms, CRMs, mobile apps, or spreadsheets for seamless address validation.

Use cases span logistics (delivery routing), field operations (rural surveys), e-commerce (precise shipping), procurement (vendor location verification), and real estate (property pinpointing), saving time and reducing errors in India-centric operations.
