Standalone API

The Lightning Enable Standalone API provides a complete REST API for integrating Bitcoin Lightning payments into any platform or application.

What is the Standalone API?

The Standalone API is a RESTful web service that enables:

• Payment Creation - Generate Lightning invoices and Bitcoin addresses
• Status Tracking - Monitor payment status in real-time
• Webhook Notifications - Receive instant payment confirmations
• Refund Processing - Handle returns and refunds
• Exchange Rates - Live BTC/USD conversion rates

Who Should Use This?

The Standalone API is ideal for:

• Custom Applications - Any platform that needs Lightning payments
• SaaS Platforms - Subscription and usage-based billing
• Marketplaces - Multi-vendor payment integration
• E-commerce Stores - Not using Kentico
• Mobile Apps - iOS, Android, React Native
• IoT Devices - Micropayments for connected devices

If you're using Xperience by Kentico, see Kentico Commerce Integration for a turnkey solution.

Key Features

Non-Custodial Architecture

Lightning Enable never touches your funds:

Your App --> Lightning Enable --> OpenNode --> Your Bitcoin Wallet

You bring your own OpenNode API key, and all funds go directly to your OpenNode account.

Multi-Currency Support

Accept payments in any currency OpenNode supports:

• USD (default)
• EUR
• GBP
• BTC (satoshis)

Real-Time Status Updates

Two options for tracking payments:

1. Webhooks (recommended) - Instant HTTP callbacks
2. Polling - Query the status endpoint

Flexible Payment Options

Every payment includes:

• Lightning Network invoice (instant, low fees)
• On-chain Bitcoin address (reliable, higher fees)
• Hosted checkout URL (no integration needed)

Quick Example

Create a payment with a single API call:

curl -X POST https://api.lightningenable.com/api/payments \
  -H "X-API-Key: your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "orderId": "ORDER-12345",
    "amount": 49.99,
    "currency": "USD",
    "description": "Premium Subscription",
    "successUrl": "https://yourapp.com/success"
  }'

Response:

{
  "invoiceId": "inv_abc123",
  "status": "unpaid",
  "amount": 49.99,
  "currency": "USD",
  "lightningInvoice": "lnbc499900n1p...",
  "onchainAddress": "bc1q...",
  "hostedCheckoutUrl": "https://checkout.opennode.com/..."
}
