You can create a custom-designed cart page in Webflow and then send users to a Shopify checkout, but it requires integrating Shopify's Buy Button or Storefront API — Webflow alone doesn’t support native Shopify checkout.
Buy Button Approach:
In Shopify, go to Sales Channels > Buy Button and create product or collection embeds.
For full cart and checkout functionality (like the Alyx site), you'll need to embed the whole cart experience, not just product buttons.
Shopify handles checkout and cart items. The Buy Button includes a floating cart and redirects to Shopify's checkout.
Advanced: Storefront API:
Gives full control to build a custom cart system in Webflow.
You’ll need to use JavaScript to:
This option mimics Alyx’s approach more closely but requires developer-level JS knowledge and Shopify API setup.
You can replicate a custom-designed cart page in Webflow and use Shopify for checkout, using either Buy Button embeds or the Shopify Storefront API (for full control). Alyx uses a headless Shopify setup, which is possible to emulate in Webflow with significant custom code and API integration.
