Lite Checkout
Balanced approach. Embed a Yuno payment form in your existing checkout page. You control the page layout while Yuno handles the payment form and PCI compliance.
Secure Fields
Maximum UI control. Embed individual card input fields (number, expiry, CVV) as secure iframes. Build a fully custom card form while maintaining SAQ-A compliance.
Direct API
Full server-side control. Integrate directly with the Yuno REST API for complete flexibility. Requires PCI DSS Level 1 certification for handling raw card data.
