Can I still achieve a similar result?

Yes. Although the plugin itself is retired, you should be able to use the following snippet of unsupported code to reposition the Shopify Buy Button inside your Squarespace product layout. This complimentary code is a direct replacement for the code that was installed in the Code Injection Footer panel.

<script>
function sfMoveShopifyButton(){
  var btn = document.querySelector("div[id^='product-component']"),
      target = document.querySelector(".product-add-to-cart");
  if (btn && target) target.appendChild(btn);
}
window.addEventListener("mercury:load", sfMoveShopifyButton);
document.addEventListener('DOMContentLoaded', sfMoveShopifyButton);
</script>

Recommended alternatives

If you’re starting fresh or want a more stable long-term solution, we recommend using Squarespace’s built-in commerce features or building directly on Shopify, rather than mixing platforms.
