Lightning Network Payment Integration - Developer Cheat Sheet

Everything you need to accept Lightning payments in your app. Copy-paste code included.

Quick Start: Accept Lightning in 5 Minutes

The fastest way: Use a Lightning address. Format: username@domain.com. Users can send sats to it from any Lightning wallet. No server needed.

Get a free Lightning address: Sign up at coinos.io - takes 30 seconds, no KYC.

Method 1: LNbits API

Create invoice: POST /api/v1/payments with {"out": false, "amount": SATS, "memo": "description"}

Check payment: GET /api/v1/payments/{payment_hash}

Method 2: BTCPay Server

Self-hosted, most flexible. Docker deploy: docker-compose up -d. API: POST /api/v1/stores/{storeId}/invoices

Method 3: Lightning Address Protocol

Simplest integration. Just display your Lightning address and let wallets handle the rest. Example: pioneeralpha6812@coinos.io
