Integrate M2Square in Minutes

// 1. Initialize M2Square SDK
import M2Square from '@m2square/sdk';

const m2square = new M2Square({
  apiKey: process.env.M2SQUARE_API_KEY,
  environment: 'production'
});

// 2. Create a payment
async function processPayment(orderData) {
  try {
    const payment = await m2square.payments.create({
      amount: orderData.amount,
      currency: orderData.currency,
      customer: {
        email: orderData.customerEmail,
        name: orderData.customerName
      },
      metadata: {
        orderId: orderData.id
      },
      returnUrl: 'https://yoursite.com/payment/complete'
    });
    
    return payment;
  } catch (error) {
    console.error('Payment failed:', error);
    throw error;
  }
}

// 3. Handle webhook notifications
app.post('/webhooks/m2square', async (req, res) => {
  const signature = req.headers['m2square-signature'];
  
  // Verify webhook signature
  const event = m2square.webhooks.verify(
    req.body,
    signature,
    process.env.WEBHOOK_SECRET
  );
  
  // Handle different event types
  switch (event.type) {
    case 'payment.completed':
      await handlePaymentCompleted(event.data);
      break;
    case 'payment.failed':
      await handlePaymentFailed(event.data);
      break;
  }
  
  res.json({ received: true });
});
