Third-Party Checkout

Third-party checkout is a payment processing solution that allows merchants to integrate external payment gateways or services into their e-commerce platforms, enabling customers to complete purchases without leaving the merchant's site. It typically involves embedding payment forms, handling secure transactions, and managing payment data through APIs provided by services like Stripe, PayPal, or Square. This approach simplifies compliance with payment regulations and reduces development overhead for merchants.
