Embedded checkout

Put a buy button on your own site. The checkout opens in an overlay on your page, and only the sites you list may show it.

Allow your sites first

Under Storefront → Embed, list the origins allowed to embed your checkout. Until you add one, the embed is off and its URL answers 404. Changes take effect within about 30 seconds.

https://example.com
Allowed. An origin is a scheme and a host.
https://example.com:8443
Allowed. Include the port if you use one.
http://localhost:5173
Allowed, for trying it on your own machine.
example.com
Refused: no scheme.
https://*.example.com
Refused: no wildcards. Each subdomain is its own entry.
https://example.com/shop
Refused: no paths. Any page on the site may embed.
http://example.com
Refused: a secure page cannot be framed by an insecure one.

The snippet

The Embed page gives you this, filled in with your store’s address and a product:

<div data-sellstamp-product="my-plugin"></div>
<script async src="https://your-store.example/embed.js"></script>
  • data-sellstamp-product is the product’s slug.
  • data-sellstamp-label changes the button text.
  • data-sellstamp-coupon and data-sellstamp-qty pre-fill the form, like a buy link.
  • Put as many placeholders on a page as you like. One script tag serves them all.
  • The button is a plain button.sellstamp-buy-button with no styling, so your CSS decides how it looks.

What the customer sees

The same checkout as your product page: options, quantity deals, the discount field, VAT and address fields where they apply, and your terms. It is the same component, so it cannot drift. A processor with its own payment page, like Stripe or PayPal, opens in your page rather than inside the frame, because those pages refuse to be framed.

What does not carry into an embed

  • Affiliate referrals. Browsers block the referral cookie inside a frame, so send affiliate traffic to your store's own page.
  • Visitor analytics. Nothing is measured inside someone else's page. Embed sales still appear in your orders.

If it does not appear

No button
The script found no data-sellstamp-product, or the slug is wrong.
An empty overlay
This page's origin is not on your list. Add it exactly as the browser reports it.
A 404
Your list is empty, or the product is not published.
