Anchor to Fulfillment Constraints Function APIFulfillment Constraints Function API

Fulfillment constraints refer to limitations or conditions that you apply when fulfilling orders. You can either specify a list of locations where cart items can be fulfilled from, or specify that cart items must be fulfilled from the same location. If the cart items with fulfillment constraints applied aren't available at the same location or any of the listed locations, then buyers won't see any shipping options at checkout. Instead, a message will show which items are out of stock, preventing the buyer from completing the purchase. To configure constraints for fulfilling orders, you can only use the Fulfillment Constraints Function API.

Shopify Functions enable you to customize Shopify's backend logic. The Fulfillment Constraints API integrates this logic into the checkout flow.

Use the API to customize fulfillment and delivery strategies for specific cart items, with associated data such as buyer identity, metafields, and location addresses.

Note

You can activate a maximum of 25 Fulfillment Constraint Functions on each store.

Anchor to Use casesUse cases

Fulfill specific items in a cart from the same location.

Anchor to TargetsTargets

A target is an identifier in shopify.extension.toml that specifies where you're injecting code into Shopify Function APIs, or other parts of the Shopify platform. Each target is composed of three to four namespaces. The name begins with a broad Shopify context and ends with the behavior of the extensible element.

Anchor to Run targetRun target

purchase.fulfillment-constraint-rule.run

The run target indicates which locations are used to fulfill specific items in a cart, either using Shopify data or hardcoded values. The target returns a list of operations that apply fulfillment constraints.

For example, you might use this to fulfill specific items in a cart from any of the locations in a list.

To optimize performance, we highly recommend that you request only the fields that your Function requires.

Caution

If the FunctionRunResult object returns fulfillment constraints that are mutually exclusive, then checkout won't return any shipping rates. For example, you might not be able to fulfill an item from two locations, or you might not be able to fulfill two items together because they must be fulfilled from different locations.

FunctionRunResult

OBJECT

The FunctionRunResult object is the output of the Function run target. The object contains the operations to apply constraints for fulfilling orders.

operations

•

[Operation!]!

non-null

The ordered list of operations to apply when fulfilling orders. You can either specify a list of locations where cart items can be fulfilled from, or specify that cart items must be fulfilled from the same location.

mustFulfillFrom

•

MustFulfillFrom

Force a set of items to be fulfilled from a specified location. If the cart item isn't stocked at the specified location, then checkout won't return any shipping rates and completing checkout will be blocked.

Anchor to deliverableLineIdsdeliverableLineIds • [ID!]: The IDs of the deliverable lines for which the constraint is applied.
Anchor to locationIdslocationIds • [ID!]! non-null: The IDs of the locations for which the cart lines must fulfill from.

mustFulfillFromSameLocation

•

MustFulfillFromSameLocation

Force a set of items to be fulfilled from the same location. If the cart items with constraints aren't stocked at the same location, then checkout won't return any shipping rates and completing checkout will be blocked.

Anchor to deliverableLineIdsdeliverableLineIds • [ID!]: The IDs of the deliverable lines for which the constraint is applied.

Examples

Restrict fulfillment to equipped locations
Fulfill orders from VIP customers from designated locations.
Prevent splitting low-subtotal carts into multiple shipments
Ensure that items in a bundle are fulfilled from the same location
Require orders of a set size to be fulfilled from warehouses
Prevent orders from being fulfilled at locations that are at capacity
Prevent discounted items from being fulfilled at retail locations.
