How to Integrate 1lookup with Custom Webhooks

// Webhook endpoint to validate emails from form submissions
app.post('/webhook/validate-email', async (req, res) => {
  const { email } = req.body;
  
  try {
    const response = await fetch('https://app.1lookup.io/api/v1/email', {
      method: 'POST',
      headers: {
        'Authorization': 'Bearer YOUR_API_KEY',
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ email })
    });
    
    const result = await response.json();
    
    // Process based on validation results
    if (result.data.classification.is_deliverable) {
      // Add to mailing list
      await addToMailingList(email);
    } else {
      // Flag for review
      await flagForReview(email, result.data);
    }
    
    res.json({ success: true, validation: result.data });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});
