Smart Pay

One simple API for all payment methods in Flutter

What is Smart Pay?

Smart Pay gives you one simple API to accept payments from multiple providers. Add Stripe today, PayPal tomorrow - your code stays the same.

// Same code works for Stripe, PayPal, Razorpay, etc.
final result = await SmartPay.checkout(PayRequest(
  amountMinorUnits: 1999, // $19.99
  currency: 'USD',
));
