Embedded checkout
Checkout that lives inside your product.
Render a complete payment form within your own pages, so customers never feel like they've left. You keep control of the experience; the provider keeps card data secure.
Illustrative preview with sample data.
Highlights
Drops into any page
Mount the checkout into a container element on your site, whether it's a single-page app or a server-rendered store.
Origin-restricted
Each session can only be embedded on the origins you list. Everywhere else, framing is blocked.
Card data stays out of scope
Card numbers are entered into the provider's secure fields and never reach your servers or ours.
Feels native
Clean, neutral styling that sits comfortably alongside your own typography and layout.
Server-side truth
Treat the browser as a hint and confirm results with signed webhooks or the API.
Same sessions as hosted
Embedded and hosted checkout share one session model, so you can switch without re-integrating.

Build
Works from the dashboard or the API.
The client SDK mounts a session created on your server. Exact SDK names may change while embedded checkout is in preview; see the developer docs for the current reference.
<div id="checkout"></div>
<script type="module">
// clientSecret comes from a session your server created
// with allowed_origins: ["https://yourstore.example"]
const checkout = await Checkout.mount("#checkout", {
clientSecret: window.__SESSION_SECRET__,
onComplete: () => location.assign("/thanks"),
});
