Stripe Payments for NestJS SaaS — Subscriptions, Metering & Billing

Integrating Stripe properly takes 2-3 weeks — checkout sessions, webhook signature verification, subscription lifecycle, failed payment retries, proration logic, and customer portal configuration. One missed webhook and your billing state drifts out of sync.

The Cloudrix SaaS Starter Kit ships with a complete Stripe integration built on the official Stripe Node.js SDK. Every webhook event is verified, every subscription state change is handled, and the customer portal is pre-configured. You get checkout, billing, metering, invoices, and plan management — all wired into your NestJS backend and Angular frontend from day one.

// Create a Stripe Checkout session
@Post('checkout')
@UseGuards(JwtAuthGuard)
async createCheckout(@CurrentUser() user: User) {
  const session = await this.stripe.checkout.sessions.create({
    customer: user.stripeCustomerId,
    mode: 'subscription',
    line_items: [{ price: 'price_pro_monthly', quantity: 1 }],
    success_url: '{{FRONTEND_URL}}/billing?success=true',
  });
  return { url: session.url };
}

// Handle webhook events
@Post('webhook')
async handleWebhook(@Req() req: RawBodyRequest) {
  const event = this.stripe.webhooks.constructEvent(
    req.rawBody, req.headers['stripe-signature'], WEBHOOK_SECRET
  );
  await this.billingService.handleEvent(event);
}
