Receiving bitcoin payments

You need to create a 'charge' to receive payments through OpenNode. A charge contains both a Lightning Network BOLT11 invoice, capable of accepting payments through the LN protocol, and a on-chain address for standard on-chain transactions.

Webhooks

In order to receive notifications when a 'charge' changes its status, you need to subscribe to the 'charge' events. You can subscribe by passing a 'callback_url' parameter on the charge payload.

❗️
Lightning Network limit
The API does not return a lightning invoice when creating a charge with an amount bigger than 500000000 sats (5 BTC).

Example

const opennode = require('opennode');
opennode.setCredentials('MY_API_KEY', 'dev');

const charge = {
  description: 'My test charge',
  amount: 10.5, // required
  currency: 'USD',
  order_id: '823320',
  customer_name: 'John Doe',
  customer_email: '[email protected]',
  notif_email: '[email protected]',
  callback_url: "https://example.com/webhook/opennode",
  success_url: 'https://example.com/order/abc123',
  auto_settle: false
};

opennode.createCharge(charge)
    .then(charge => {
        console.log(charge);
    })
    .catch(error => {
        console.error(`${error.status} | ${error.message}`);
    });

curl https://api.opennode.co/v1/charges \
    -X POST \
  -H "Content-Type: application/json" \
  -H "Authorization: YOUR_API_KEY" \
  -d '{ "description": "My test charge",
        "amount": 10.5,
      "currency": "USD",
      "order_id": "823320",
      "customer_name": "John Doe",
      "customer_email": "[email protected]e.com",
      "notif_email": "[email protected]",
      "callback_url": "https://example.com/webhook/opennode",
      "success_url": "https://example.com/order/abc123",
      "auto_settle": false }'

If the request was correctly sent, the API will reply with a 201 status code and charge object:

You can use OpenNode's native checkout experience by redirecting your user to the checkout endpoint:

Development - https://dev-checkout.opennode.com/ {id}
Production -https://checkout.opennode.com/ {id}

If you want to build your own checkout experience you can create BIP21 + BOLT11 QR code using the uri field.
