In this final video of the payment series, you'll implement subscription plans and payment processing using Stripe API integration—and actually start charging users for your app.

What You'll Learn:
1. How to get a Stripe API key (free account)
2. Setting up restricted API keys for third-party apps
3. Understanding Stripe API permissions (alerts, billing, payment methods, tax)
4. Integrating Stripe with Lovable
5. Testing your payment flow
6. Adding free trial options

What's Next? Consider adding:
- Subscription cancellation features
- Settings page for subscription management
- Usage limits to prevent abuse
- Additional payment-related features

Congratulations, You're Now a Product Builder!
You've just built a full-featured app with AI capabilities and payment processing—all without writing complex code from scratch. You called APIs, managed user stories, and shipped a real product.

I built this for our public service community. If you find it useful, share it across the public service, please. And when you build something, tag me on LinkedIn ( / yongkiat ) I'd love to see what you create!

Let's grow together. See you in the videos!
