Create an offline DIGIPIN microservice API for precise location mapping in India

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

What is DIGIPIN? DIGIPIN (Digital Pincode) is a 10-character alphanumeric code introduced by India Post. It maps any 3x3 meter square in India to a unique digital address. This helps precisely locate homes, shops, or landmarks, especially in areas where physical addresses are inconsistent or missing.

What this workflow does This workflow creates a fully offline DIGIPIN microservice using only JavaScript - no external APIs are used.

You get two HTTP endpoints:

• GET /generate-digipin?lat={latitude}&lon={longitude} → returns a DIGIPIN
• GET /decode-digipin?digipin={code} → returns the latitude and longitude

You can plug this into any system to:

• Convert GPS coordinates to a DIGIPIN
• Convert a DIGIPIN back to coordinates

How it works

1. An HTTP Webhook node receives the request
2. A JS Function node either encodes or decodes based on input
3. The result is returned as a JSON response

All the logic is handled inside the workflow - no API keys, no external calls.

Why use this

• Fast and lightweight
• Easily extendable: you can connect this to forms, CRMs, apps, or spreadsheets
• Ideal for field agents, address validation, logistics, or rural operations
