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 to Shopify Checkout, you'll need to use Shopify's Buy Button sales channel and dynamically adjust it based on user interaction.

​

1. Set Up Shopify Buy Button

​

• Log in to Shopify Admin and go to Settings > Apps and sales channels.
• Click "Buy Button", or install it if not already added.
• Select Create a Buy Button, then choose a Single Product or Collection.
• In the customization page, style the button (optional), then Generate Code.
• Copy the JavaScript snippet provided.

2. Embed Static Button in Webflow

​

• In Webflow, go to the page or component where you want to place the payment button.
• Use an Embed element (from the Add panel).
• Paste the Shopify JS snippet into the Embed element.

​

Note: This creates a static Buy Button. To make it dynamic for different products, proceed to the next step.

3. Make the Button Dynamic via Webflow CMS

​

• Create a CMS Collection in Webflow (e.g., Products).
• Add fields for:
• Product Title
• Product Image
• Shopify Product ID
• Any additional variant info
• In your CMS Collection Page or List, use a Dynamic Embed element (in a Collection Item).

​

Example Setup:

• Inside the Embed element, insert {{wf {fieldName} }} to inject the dynamic Product ID.
• Modify Shopify’s embed code to use dynamic JS to refer to each product using the stored product ID.

​

Note: Since Shopify’s Buy Button code is not designed to accept just a Product ID from outside, you typically need to either:

• Create separate Buy Buttons for each product in Shopify, copy the embed codes, and paste them into your Webflow CMS items via a Rich Text or Embed field.
• Redirect users to the Shopify Checkout via custom links, which leads to the next method.

4. Use Shopify Checkout URL for Direct Redirect

​

• You can skip the Buy Button and instead create a direct Shopify checkout link.
• Format:  

  https://[yourshop].myshopify.com/cart/[variant_id]:1

​

Example:  

  https://yourstore.myshopify.com/cart/1234567890:1

​

• In Webflow CMS:
• Add a field for Shopify Variant ID (number).
• Use a Webflow Link Block or Button, and bind the href like this:  

    https://yourstore.myshopify.com/cart/{{wf {variant_id} }}:1

​

This creates a dynamic Buy Now button that redirects directly to Shopify Checkout with the correct item and quantity.

5. Optional: Add Quantity or Variant Selection

​

• Webflow CMS doesn’t support dynamic variant selectors out-of-the-box.
• You can:
• Build a custom form in Webflow with dropdowns or radios for options.
• Use custom JavaScript to read those values and modify the checkout URL accordingly on click.

Summary

​

To integrate a dynamic Shopify payment button on Webflow:

• Use Shopify Buy Buttons for visual embeds (less dynamic).
• Or create direct Shopify Checkout URLs using stored variant IDs for lightweight, dynamic Buy Now buttons.
• Use Webflow CMS fields and dynamic routing to personalize each product’s checkout link.

​

For most use cases, using Shopify Checkout URLs is faster and more scalable in Webflow.
