Get Your API Key

Navigate to your Dashboard and copy your production API key: 
c2c_live_a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6...
Never expose your API key in client-side code or public repositories. Always use it server-side only.

​
Make Your First Payment

​
1. Create a Payment

Make a POST request to create a payment: 
const response = await fetch('https://card2crypto.cc/api/v1/payments', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer c2c_live_your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    amount: 5000, // $50.00 in cents
    currency: 'usd',
    customer_email: 'customer@example.com',
    description: 'Order #1234',
    success_url: 'https://yoursite.com/success',
    cancel_url: 'https://yoursite.com/cancel'
  })
});

const payment = await response.json();
console.log(payment.checkout_url);

​
2. Redirect to Checkout

The API returns a checkout_url. Redirect your customer to this URL: 
window.location.href = payment.checkout_url;
The customer will see a checkout page where they can enter their card details.

​
3. Handle Webhooks

Set up a webhook endpoint to receive payment notifications: 
const crypto = require('crypto');

app.post('/webhooks/card2crypto', (req, res) => {
  // Verify signature
  const signature = req.headers['x-card2crypto-signature'];
  const payload = JSON.stringify(req.body);

  const expectedSignature = crypto
    .createHmac('sha256', process.env.WEBHOOK_SECRET)
    .update(payload)
    .digest('hex');

  if (signature !== expectedSignature) {
    return res.status(401).send('Invalid signature');
  }

  // Process webhook
  const { event, payment } = req.body;

  if (event === 'payment.completed') {
    console.log(`Payment ${payment.id} completed!`);
    // Update your database, send confirmation email, etc.
  }

  res.status(200).send('OK');
});
Learn more about webhook security in the Webhook Security guide.

​
Test Your Integration

Use the Payment Testing Tool in your dashboard to quickly test payment creation without writing code.
All payments are live and real. Test with small amounts like $0.50 to verify your integration works correctly.
