📱 One-Click Deploy

🔧 Configuration

Stripe Webhook Setup

1. Go to your Stripe Dashboard → Webhooks
2. Add endpoint: https://your-domain.com/api/webhooks/stripe
3. Select events:
   • customer.subscription.deleted
   • customer.subscription.updated
   • invoice.payment_failed
   • customer.subscription.trial_will_end
4. Copy the webhook secret to your environment variables

Supabase Setup

1. Create a new Supabase project
2. Run the SQL schema from supabase-schema.sql
3. Enable Row Level Security (RLS) policies
4. Set up authentication (optional for MVP)

📊 Usage

1. Cancel Intent Detection

// Your app's cancel button
document.getElementById('cancel-button').addEventListener('click', async (e) => {
  e.preventDefault();
  
  const response = await fetch('/api/cancel-intent', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      userId: 'user_123',
      customerId: 'cus_stripe_id',
      subscriptionId: 'sub_stripe_id',
      plan: 'Pro',
      mrr: 99
    })
  });
  
  const result = await response.json();
  
  if (result.status === 'offer') {
    // Show the retention offer
    showRetentionModal(result.offer);
  } else {
    // Proceed with cancellation
    proceedWithCancellation();
  }
});

2. Embed the Modal Script

<!-- Add to your website -->
<script>
  window.exitZeroConfig = {
    apiUrl: 'https://your-exitzero-domain.com',
    customerId: 'your_customer_id'
  };
</script>
<script src="https://your-exitzero-domain.com/api/exit-zero-script.js"></script>

3. Churn Audit

// Request a churn audit
const response = await fetch('/api/churn-audit', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    email: 'founder@yourcompany.com',
    stripeCustomerId: 'cus_stripe_id' // optional
  })
});
