Storefront URLs, delivery estimates, and carrier names are now available as standard API fields. These values were commonly modeled as Custom Fields when building agentic or headless checkout experiences. This enhancement allows you to provide these values while minimizing the number of Types and Custom Fields used in your project.

On a Store, the new storefront field groups customer-facing URLs and policy links. These include the checkout and order URL templates and links to policy pages such as terms of service, privacy, and refunds. For more information, see the Stores API.
On a Cart and Order, the new estimatedDelivery field on ShippingInfo records the time window during which a shipment is expected to be delivered. You can set it standalone with the new Set Estimated Delivery update action, or inline when selecting a Shipping Method. The estimate is cleared automatically when the shipping address changes.
On a ShippingMethod, the new carrier field records the name of the carrier that delivers the parcel.
