Hosted Checkout Page Integration

Users can scan the QR code or copy the address on the hosted checkout page to make the payments.

We recommend merchants to integrate with ReelPay's hosted checkout interface. You will only need two steps to start accepting crypto payments. When the integration is done. Your server will be able to call the checkout URL API and present ReelPay's hosted checkout page to your users.
