Embed Kunaki Checkout Seamlessly

I already sell my CDs through Kunaki and now I want the whole purchase journey—specifically Kunaki’s checkout flow—sitting right on a page of my own domain.
Here’s the outcome I’m after: when a visitor browses my site and clicks “Buy,” the familiar Kunaki checkout appears inside my page (iframe, modal, or whatever approach you suggest), processes the payment, and triggers Kunaki’s normal automatic production-and-shipping routine. I do not want to touch the XML catalog option or log in afterward to release orders; the integration must leave Kunaki’s shipping automation fully intact.

Visual styling can stay exactly as Kunaki presents it, so no template re-skin is necessary. What does matter is that a customer already logged into my site should flow straight into Kunaki checkout with their name, email, and address pre-filled (or at least passed through) so they don’t have to type everything twice.

Deliverables
• A working page on my site (I can provide FTP / CMS access) with Kunaki’s checkout embedded and functional for live orders.
• Account-data hand-off between my site’s user session and Kunaki checkout verified in a test transaction.
• Brief written instructions so I can reproduce the setup on additional pages or domains if needed.

If you’ve handled Kunaki, embedded checkouts, or similar fulfillment services before, let me know your approach and timeline and we’ll get rolling.
