Example: Basic Premium Flow

One common pattern for granting premium access after payment.

This is just one approach. Your integration may differ based on your app architecture, authentication system, and business requirements.

Flow

1. User enters email in funnel → Registration Webhook fires → Create account if new

2. User pays → Stripe/Paddle Webhook fires → Set premium = true

---

Registration Webhook Handler

app.post('/webhooks/zellify-registration', (req, res) => {
  const { email, answers } = req.body;
  
  let user = await db.users.findByEmail(email);
  if (!user) {
    user = await db.users.create({ email, premium: false });
  }
  
  res.status(200).send('OK');
});

---

Payment Webhook Handler

Stripe (checkout.session.completed):

const email = session.customer_details.email;
await db.users.update({ email }, { premium: true });

Paddle (transaction.completed):

const email = event.data.customer.email;
await db.users.update({ email }, { premium: true });
