Add Checkout Page to Super.so

Use Checkout Page to sell digital products, physical products, services and more on your Super site.

Super is an amazing tool to create websites with Notion.

In this guide, we show you how you can sell digital downloads, subscriptions, products & services directly on your Super site, like in this demo.

We’ll explain how you add one-page checkout embeds, checkout pop-ups and checkout links.

After signing up for Checkout Page and creating a checkout, follow the steps below.

With Checkout Page, you can easily create a one-page checkout and add it to your site in different ways.

There are 3 ways you can add one-page checkouts to Super:

1. Embed a checkout on your site
2. Open a checkout in a pop-up
3. Link to a checkout with a link or button

Add the Super Embed block

To add one-page checkouts to Super sites, we need to be able to add some Custom HTML. Super makes this possible by creating a super-embed: block.

1. Open your Super site in the dashboard and click Code
2. In the Head tab, paste the following code: ^

<script>
  function clearBlock(el) {
    const node = el.parentElement.parentElement;
    node.innerHTML = "";
    return node;
  }

  const SELECTOR = "code:not([super-embed-seen])";

  function setupEmbeds() {
    document.querySelectorAll(SELECTOR).forEach((node) => {
      node.setAttribute("super-embed-seen", 1);

      if (node.innerText.startsWith("super-embed:")) {
        const code = node.innerText.replace("super-embed:", "");
        const parentNode = clearBlock(node);

        parentNode.innerHTML = code;

        parentNode.querySelectorAll("script").forEach((script) => {
          if (!script.src && script.innerText) {
            eval(script.innerText);
          } else {
            const scr = document.createElement("script");

            scr.src = script.src;

            document.body.appendChild(scr);
          }
        });
      }
    });
  }

  setupEmbeds();

  var observer = new MutationObserver(function (mutations) {
    if (document.querySelector(SELECTOR)) {
      setupEmbeds();
    }
  });

  observer.observe(document, {
    attributes: false,
    childList: true,
    characterData: false,
    subtree: true,
  });
</script>

Now, continue with one of the checkout options below: embed, pop-up or payment link.
