On August 28, 2025, Shopify announced a major enhancement to its Storefront API. The update introduces support for vaulted cards and store credit directly within the checkout flow, creating new opportunities for headless storefronts and mobile commerce applications.
What Has Changed?
With this update, authenticated buyers can now seamlessly use their saved payment cards or store credit during checkout on headless storefronts and mobile apps. By simply appending the customerAccessToken, the checkout process becomes both secure and frictionless, eliminating unnecessary barriers that could cause cart abandonment.


Why It Matters for Headless Commerce
This improvement addresses two of the most critical factors in modern e-commerce: security and customer experience. A checkout flow that allows buyers to quickly select a saved card or apply store credit reduces friction, speeds up transactions, and increases customer trust. For brands, the potential result is a smoother payment process that can directly translate into higher conversion rates.
The Impact on Developers and Merchants
For developers building headless commerce projects, this is a powerful step forward. It allows for more flexible, user-friendly, and secure integrations across custom storefronts and mobile apps. For merchants, it means offering customers the same convenience they expect from traditional Shopify checkouts while still leveraging the freedom of headless architectures.
Final Thoughts
The addition of vaulted card and store credit support in the Storefront API underscores Shopify’s commitment to empowering developers and merchants with tools that elevate the buying experience. By reducing friction at checkout and enhancing security, this update has the potential to reshape how headless commerce projects handle payments. For forward-thinking brands, it’s a chance to strengthen customer loyalty while optimizing conversion performance.
