How can I integrate a dynamic payment button to Shopify Checkout on my Webflow site?

To integrate a dynamic payment button on your Webflow site that redirects users to Shopify Checkout, you’ll need to use Shopify Buy Buttons with dynamic content passed from Webflow. Here's how:

1. Set Up Products in Shopify

• Log into Shopify Admin and create the products you want to sell.
• Ensure each product has a price, image, and inventory set up properly.

2. Enable Buy Button Sales Channel

• In Shopify Admin, go to Sales Channels > Buy Button.
• Click Create a Buy Button, then choose Product.
• Select a product and customize the button appearance.
• Click Next, then Copy Code (you’ll use the product or variant ID from this snippet, not the script itself).

3. Collect Product/Variant IDs

• Paste the copied code snippet into a plain text editor.
• From the snippet, extract either the product ID or variant ID (this is typically a string of numbers or alphanumeric).
• Store these IDs — you’ll use them to generate dynamic buttons via JavaScript.

4. Add Shopify Buy SDK to Webflow

• In Webflow, go to Page Settings or Project Settings > Custom Code.

• Add the Shopify Buy SDK script in the Before section:

  Script URL:
  https://sdks.shopifycdn.com/buy-button/latest/buy-button-storefront.min.js

5. Dynamically Generate Buttons in Webflow

• Add a custom embed element or div with a unique class or ID (e.g., shopify-button-container) wherever you want the button.

• In a <script> embed below the container, write JavaScript code to:

• Initialize the Shopify Buy client using your Shopify domain and Storefront access token (get this from Shopify Admin under Apps > Manage private apps).

• Dynamically render the correct product or variant using the extracted IDs.

• You can pass dynamic variant IDs via Webflow CMS fields using custom attributes or embeds.

6. Use Webflow CMS for Dynamic Data

• If your site uses Webflow CMS, assign each product in your collection with a Shopify variant ID.
• Use Webflow CMS Embed Fields to inject the variant ID into your dynamic pages, so the script knows which product to render.

7. Handle Shopping Flow & Checkout

• When users click the button, they are taken directly to Shopify’s secure checkout.
• Shopify manages the full checkout and payment process.

Summary

To integrate a dynamic Shopify Checkout button on Webflow, use Shopify Buy Buttons with the Storefront API and Webflow CMS support. Add the Shopify Buy SDK, map variant IDs using CMS or static embeds, and write JavaScript to mount the button. This setup lets users seamlessly purchase through Shopify while browsing your custom-designed Webflow site.
