Card payment

Use this demo to test a complete card payment before copying the integration pattern into your app:

1. Review the checkout form values: amount, currency, customer, client_reference, and optional idempotency_key.
2. Enter a test card in the secure card fields rendered by the SDK.
3. Choose the presentation mode you want to test: embedded or redirect.
4. Click Deposit to create the payment and complete any required authentication.
5. Inspect the result payload and reconcile the final status with your backend/webhooks before fulfillment.
