Migration Overview

// Every SaaS app has its own Stripe setup
const stripe = new Stripe(process.env.STRIPE_SECRET_KEY);

// Webhooks go everywhere — no project isolation
app.post('/webhooks/stripe', async (req, res) => {
  const event = stripe.webhooks.constructEvent(req.body, sig, secret);
  // Is this for SaaS-1 or SaaS-2? Who knows...
});

// Customers are global — no project scoping
const customer = await stripe.customers.create({
  email: 'user@example.com',
});

// You build checkout, portal, subscription management from scratch
// For every. single. product.

// One API, project-scoped, API key authenticated
const res = await fetch(
  `${BILLSTACK_URL}/api/billstack/teams/${TEAM}/projects/${PROJECT}/customers`,
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ email: 'user@example.com' }),
  }
);

// Webhooks are routed automatically per project
// Customer portal is self-hosted and ready to use
// Analytics dashboard is built in
