To implement a payment gateway in React Native, follow these steps:
- Install SDK: Use npm install @stripe/stripe-react-native for Stripe.
- Initialize: Import and wrap your app with StripeProvider using your publishable key.
- Create Payment Form: Use provided components to build a payment form.
- Server-Side Payment Intent: Generate a payment intent on your server to get a client secret.
- Confirm Payment: Use the client secret to confirm payment on the client side, handling errors and successes appropriately.
- Ensure proper security, error handling, and thorough testing in a test environment. Implement 3D Secure for enhanced security and customize the UI as needed.
