Smart Pay

Unified payments for Flutter with a single API. Configure Stripe today, more gateways soon, and present a unified checkout experience.

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',
));
