YardPay

React SDK demo

Plug in your sandbox API keys and run a full payment flow against @quickpay/react. This page creates a checkout session for you and hands the client_secret to the React components.

Sandbox only

Only paste test keys (pk_test_... and sk_test_...). Your secret key is forwarded through a Next.js route straight to the YardPay API and is never logged, persisted, or reused. The demo refuses sk_live_ keys.
