Hosted Checkout

Create a checkout session and redirect the user to XValuePay's hosted checkout page. The seller authenticates separately via magic-link email.

How marketplace mode works: Provide both buyer and seller emails. The buyer uses the checkout URL to authenticate and pay. The seller receives a magic-link email to authenticate, set up a payout account, and accept the transaction.

To test both sides simultaneously, use the page — it shows buyer and seller iframes side by side with a live timeline.
