Introduction

Using Shopify’s Buy Button allows merchants to embed shopping functionalities on external sites while retaining Shopify’s checkout features. However, by default, the checkout process is redirected to a Shopify subdomain (e.g., `abc.myshopify.com`). Many merchants prefer using a custom domain for checkout to maintain consistent branding and instill customer trust.

This article provides a guide to setting up a custom domain for your Buy Button checkout, ensuring your checkout URL reflects your own domain.

1. Understanding Shopify Buy Button Limitations

The Shopify Buy Button provides a streamlined checkout process for merchants looking to sell products outside their main Shopify store. However, it comes with some limitations:

• Checkout Redirects to Shopify Domain: By default, the checkout is hosted on Shopify’s subdomain, not your custom domain.
• Session and Cart Integration: Items added via Buy Button on an external site may not synchronize with a Shopify storefront cart, causing cart session issues.
• Limited Customization: Although Buy Buttons support basic customization, more complex design control over the checkout process requires additional workarounds.

2. How to Use a Custom Domain for Checkout

Shopify doesn’t officially support direct custom domain checkout for Buy Buttons. However, a workaround involves modifying the Buy Button embed code to use a custom domain for the checkout.

Below is a solution shared by a Shopify community member that involves editing the Buy Button script’s domain variable to your custom domain. Note: This method requires that you connect a subdomain, like `checkout.yourdomain.com`, to Shopify’s Online Store channel.

3. Step-by-Step Guide: Setting Up a Custom Domain for Buy Button

Follow these steps to set up your custom domain for the Shopify Buy Button checkout:

1. Configure a Subdomain:
   • In your DNS settings, set up a subdomain (e.g., `checkout.yourdomain.com`).
   • Point this subdomain to Shopify by adding a CNAME record with the value `shops.myshopify.com`.
2. Connect the Subdomain to Shopify:
   • Go to your Shopify admin dashboard, then navigate to Online Store > Domains.
   • Add your subdomain (e.g., `checkout.yourdomain.com`) as a third-party domain.
   • Follow the verification steps to ensure your subdomain is properly linked.
3. Edit the Buy Button Script:
   • Copy the Buy Button embed code from Shopify.
   • In the code, locate the `ShopifyBuy.buildClient` function.
   • Replace the `domain` parameter with your custom subdomain, as shown below:

   function ShopifyBuyInit() {
       var client = ShopifyBuy.buildClient({
           domain: 'checkout.yourdomain.com',
           storefrontAccessToken: 'YOUR_ACCESS_TOKEN',
       });
   }
                   

4. Embed the Edited Code on Your Site:
   • Place the modified Buy Button code on your external website where you want the Buy Button to appear.
   • Test the checkout flow by adding an item to the cart and proceeding to checkout to ensure it redirects to `checkout.yourdomain.com`.

Following these steps should allow customers to see your custom domain in the checkout URL, providing a more cohesive and branded checkout experience.

4. Troubleshooting Common Issues

Here are some common issues you may encounter and tips on resolving them:

• Buy Button Fails to Load: Ensure that the `domain` parameter is set correctly in the Buy Button code and that the subdomain points to `shops.myshopify.com` in your DNS settings.
• Session Issues: If you notice items disappearing from the cart, it may be due to session handling. Shopify Buy Buttons don’t fully synchronize cart data with Shopify storefronts.
• SSL Certificate Error: If SSL fails to work on your custom subdomain, ensure it’s properly connected in Shopify under Online Store > Domains.

5. SEO and Branding Considerations

Using a custom domain for Buy Button checkouts offers the following SEO and branding advantages:

• Improved Brand Cohesion: Customers see your brand’s domain at checkout, enhancing trust and providing a more seamless experience.
• Google Analytics Tracking: Since the checkout remains on your domain, Google Analytics can track user sessions more effectively across the customer journey, maintaining data continuity.
• Custom Redirects for Continuity: Consider setting up redirects on your custom subdomain so that if customers attempt to navigate away from checkout, they’re sent back to your primary site.

These steps help ensure that using Shopify Buy Buttons doesn’t compromise your branding and marketing strategy.

Conclusion

Using a custom domain for your Shopify Buy Button checkout process enhances the brand experience and provides a unified customer journey. While Shopify doesn’t officially support custom domains for Buy Button checkouts, the workaround discussed here allows for greater control over the checkout URL.

By following the steps outlined above, you can offer a branded checkout experience that improves customer trust and supports your business’s marketing objectives.
