Accelerated Checkouts Now Support Product Add-Ons

Shopify has updated its accelerated checkout functionality to support add-on products directly from the product page. Customers can now purchase a main product along with related add-ons (such as a TV with an extended warranty) using Shop Pay, Apple Pay, Google Pay, and other accelerated checkout options without navigating to the cart page first.

Impact on App Developers

This change affects developers building apps that implement product add-ons, upsells, or bundling features. Apps using Shopify’s cart transform API or product subscription extensions can now maintain their add-on functionality when customers choose accelerated checkout methods. Previously, these fast checkout options bypassed the cart page where many add-on selections occurred, creating friction in the purchase flow.

Technical Considerations

Developers should verify their add-on implementations work correctly with accelerated checkout buttons. Apps that modify cart contents or add supplementary products need to ensure these modifications persist through the accelerated checkout flow. The update applies to Shopify’s native add-on functionality and should extend to third-party apps using supported APIs.

Merchants using apps for warranties, insurance, gift wrapping, or product bundles may see improved conversion rates as customers can complete purchases faster. Developers should review Shopify’s documentation on cart transforms and checkout extensibility to confirm their implementations align with the updated accelerated checkout behavior.
