--- title: Fulfillment Constraints Function API description: Use the Fulfillment Constraints Function API to configure constraints for fulfilling orders. api_version: 2025-07 api_type: functions api_name: fulfillment-constraints source_url: html: https://shopify.dev/docs/api/functions/latest/fulfillment-constraints md: https://shopify.dev/docs/api/functions/latest/fulfillment-constraints.md --- # Fulfillment Constraints Function API Fulfillment constraints refer to limitations or conditions that you apply when [fulfilling orders](https://help.shopify.com/manual/fulfillment/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](https://shopify.dev/docs/api/functions/current) 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. ### Use cases * Fulfill specific items in a cart from the same location. * Fulfill specific items in a cart from any of the locations in a list. ## Function target Checkout ![Function Target](https://cdn.shopify.com/shopifycloud/shopify-dev/production/assets/assets/images/target-diagrams/fulfillment-constraints-target-diagram-CscXm3zJ.png) Compatibility with Shopify surfaces Supported (9) Partially supported (3) Unsupported (2) * [B2B](https://shopify.dev/docs/apps/build/b2b): Supported * [Cart](https://shopify.dev/docs/storefronts/themes/architecture/templates/cart): Supported * [Checkout](https://shopify.dev/docs/apps/build/checkout): Supported * [Create Order API](https://shopify.dev/docs/api/admin-graphql/latest/mutations/orderCreate): Supported * [Draft Order (Admin)](https://shopify.dev/docs/apps/build/b2b/draft-orders): Supported * [Draft Order (Checkout)](https://shopify.dev/docs/apps/build/b2b/draft-orders): Supported * [Order Edit (Admin)](https://shopify.dev/docs/apps/build/orders-fulfillment/order-management-apps/edit-orders): Partially supported This option is available only for new items. * [Order Edit (Checkout)](https://shopify.dev/docs/apps/build/orders-fulfillment/order-management-apps/edit-orders): Not supported * [POS](https://shopify.dev/docs/apps/build/pos): Partially supported POS is available only when shipping to a customer. * [Pre-order and Try Before You Buy](https://shopify.dev/docs/apps/build/purchase-options/deferred): Not supported * [Shopify Admin](https://shopify.dev/docs/apps/build/functions/input-output/metafields-for-input-queries#creating-your-merchant-interface): Supported * [Storefront](https://shopify.dev/docs/storefronts/headless/building-with-the-storefront-api/): Partially supported This option is available only with Buy with Prime. * [Storefront Accelerated Checkout](https://shopify.dev/docs/storefronts/themes/pricing-payments/accelerated-checkout): Supported * [Subscription (Recurring Orders)](https://shopify.dev/docs/apps/build/purchase-options/subscriptions): Supported *** ## Getting started Scaffolding the function using [Shopify CLI](https://shopify.dev/docs/api/shopify-cli) will automatically configure your TOML file. You can alter the default [configuration](https://shopify.dev/docs/api/functions/2025-07#configuration) to customize the way your function operates. ## Terminal ```terminal shopify app generate extension --template fulfillment_constraints ``` [![](https://shopify.dev/images/icons/32/tutorial.png)![](https://shopify.dev/images/icons/32/tutorial-dark.png)](https://shopify.dev/docs/apps/build/orders-fulfillment/order-routing-apps/build-fulfillment-constraints-function) [TutorialBuild a fulfillment constraints function](https://shopify.dev/docs/apps/build/orders-fulfillment/order-routing-apps/build-fulfillment-constraints-function) *** ## Targets A [target](https://shopify.dev/docs/apps/build/app-extensions/configure-app-extensions#targets) 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. *** ### Run target `cart.fulfillment-constraints.generate.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. * Input OBJECT The `Input` object is the complete GraphQL schema that your function can query as input to customize fulfillment constraints. Your function receives only the fields that you request in the input query. To optimize performance, we highly recommend that you request only the fields that your function requires. * cart Cart! non-null The cart where the Function is running. A cart contains the merchandise that a customer intends to purchase and information about the customer, such as the customer's email address and phone number. * attribute Attribute The custom attributes associated with a cart to store additional information.

For example, an athletics store might create different collections for running attire and accessories. * ids \[ID!]! requiredDefault:\[] ### Arguments A comma-separated list of [globally-unique collection IDs](https://shopify.dev/docs/api/usage/gids) that are associated with the product. For example, `gid://shopify/Collection/123`, `gid://shopify/Collection/456`. *** * collection​Id ID! non-null ### Fields A [globally-unique ID](https://shopify.dev/docs/api/usage/gids) for the collection. * is​Member Boolean! non-null Whether the product is in the specified collection. * is​Gift​Card Boolean! non-null Whether the product is a gift card. * metafield Metafield A [custom field](https://shopify.dev/docs/apps/build/custom-data) that stores additional information about a Shopify resource, such as products, orders, and [many more](https://shopify.dev/docs/api/admin-graphql/latest/enums/MetafieldOwnerType). Using [metafields with Shopify Functions](https://shopify.dev/docs/apps/build/functions/input-output/metafields-for-input-queries) enables you to customize the checkout experience. * namespace String ### Arguments A category that organizes a group of metafields. Namespaces are used to prevent naming conflicts between different apps or different parts of the same app. If omitted, then the [app-reserved namespace](https://shopify.dev/docs/apps/build/custom-data/ownership) is used. * key String! required The unique identifier for the metafield within its namespace. A metafield is composed of a namespace and a key, in the format `namespace.key`. *** * json​Value JSON! non-null ### Fields The data that's stored in the metafield, using JSON format. * type String! non-null The [type of data](https://shopify.dev/apps/metafields/types) that the metafield stores in the `value` field. * value String! non-null The data that's stored in the metafield. The data is always stored as a string, regardless of the [metafield's type](https://shopify.dev/apps/metafields/types). * product​Type String A custom category for a product. Product types allow merchants to define categories other than the ones available in Shopify's [standard product categories](https://help.shopify.com/manual/products/details/product-type). * title String! non-null The localized name for the product that displays to customers. The title is used to construct the product's handle, which is a unique, human-readable string of the product's title. For example, if a product is titled "Black Sunglasses", then the handle is `black-sunglasses`. * vendor String The name of the product's vendor. * requires​Shipping Boolean! non-null Whether the item needs to be shipped to the customer. For example, a digital gift card doesn't need to be shipped, but a t-shirt does need to be shipped. * sku String A case-sensitive identifier for the product variant in the merchant's store. For example, `"BBC-1"`. A product variant must have a SKU to be connected to a [fulfillment service](https://shopify.dev/docs/apps/build/orders-fulfillment/fulfillment-service-apps/build-for-fulfillment-services). * title String The localized name for the product variant that displays to customers. * weight Float The product variant's weight, in the system of measurement set in the `weightUnit` field. * weight​Unit Weight​Unit! non-null The unit of measurement for weight. * GRAMS, KILOGRAMS, OUNCES, POUNDS * quantity Int! non-null The quantity of the item that the customer intends to purchase. * delivery​Groups \[Cart​Delivery​Group!]! non-null A collection of items that are grouped by shared delivery characteristics. Delivery groups streamline fulfillment by organizing items that can be shipped together, based on the customer's shipping address. For example, if a customer orders a t-shirt and a pair of shoes that can be shipped together, then the items are included in the same delivery group. In the [Order Discount](https://shopify.dev/docs/api/functions/reference/order-discounts) and [Product Discount](https://shopify.dev/docs/api/functions/reference/product-discounts) legacy APIs, the `cart.deliveryGroups` input is always an empty array. This means you can't access delivery groups when creating Order Discount or Product Discount Functions. If you need to apply discounts to shipping costs, then use the [Discount Function API](https://shopify.dev/docs/api/functions/reference/discount) instead. * cart​Lines \[Cart​Line!]! non-null Information about items in a cart that a customer intends to purchase. A cart line is an entry in the customer's cart that represents a single unit of a product variant. For example, if a customer adds two different sizes of the same t-shirt to their cart, then each size is represented as a separate cart line. * attribute Attribute The custom attributes associated with a cart to store additional information. Cart attributes allow you to collect specific information from customers on the **Cart** page, such as order notes, gift wrapping requests, or custom product details. Attributes are stored as key-value pairs. Cart line attributes are equivalent to the [`line_item`](https://shopify.dev/docs/apps/build/purchase-options/subscriptions/selling-plans) object in Liquid. * key String ### Arguments The key of the cart attribute to retrieve. For example, `"gift_wrapping"`. *** * key String! non-null ### Fields The key or name of the attribute. For example, `"customer_first_order"`. * value String The value of the attribute.

Each operation specifies whether to fulfill items from the same location or from a specified location on a list. Shopify processes your response to determine how to best fulfill orders. This return must follow the schema defined in the `CartFulfillmentConstraintsGenerateRunResult` object. Caution If the `CartFulfillmentConstraintsGenerateRunResult` 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. * Cart​Fulfillment​Constraints​Generate​Run​Result OBJECT The `CartFulfillmentConstraintsGenerateRunResult` 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](https://help.shopify.com/manual/fulfillment/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. * deliverable​Lines​Must​Fulfill​From​Add Deliverable​Lines​Must​Fulfill​From​Add​Operation 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. * deliverable​Line​Ids \[ID!] The IDs of the deliverable lines for which the constraint is applied. * location​Ids \[ID!]! non-null The IDs of the locations for which the cart lines must fulfill from. * deliverable​Lines​Must​Fulfill​From​Same​Location​Add Deliverable​Lines​Must​Fulfill​From​Same​Location​Add​Operation 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. * deliverable​Line​Ids \[ID!] The IDs of the deliverable lines for which the constraint is applied. Examples * ### Prevent splitting low-subtotal carts into multiple shipments This function checks if the cart is below a certain configurable subtotal and if so it returns a fulfillment constraint that prevents the cart from being split into multiple shipments #### cart.fulfillment-constraints.generate.run ##### Input Query (Rust) ```graphql query Input { cart { cost { subtotalAmount { amount currencyCode } } deliverableLines { id } } fulfillmentConstraintRule { metafield(namespace: "$app:fulfillment-constraints", key: "configuration") { jsonValue } } } ``` ##### Input Query (JavaScript) ```graphql query RunInput { cart { cost { subtotalAmount { amount currencyCode } } deliverableLines { id } } fulfillmentConstraintRule { metafield(namespace: "$app:fulfillment-constraints", key: "configuration") { jsonValue } } } ``` ##### Input Object (Rust) ```json { "cart": { "cost": { "subtotalAmount": { "amount": "49.99", "currencyCode": "USD" } }, "deliverableLines": [ { "id": "gid://shopify/CartLine/1" }, { "id": "gid://shopify/CartLine/2" } ] }, "fulfillmentConstraintRule": { "metafield": { "jsonValue": { "threshold": 50.0 } } } } ``` ##### Input Object (JavaScript) ```json { "cart": { "cost": { "subtotalAmount": { "amount": "49.99", "currencyCode": "USD" } }, "deliverableLines": [ { "id": "gid://shopify/CartLine/1" }, { "id": "gid://shopify/CartLine/2" } ] }, "fulfillmentConstraintRule": { "metafield": { "jsonValue": { "threshold": 50.0 } } } } ``` ##### Function Code (Rust) ```rust use crate::schema; use shopify_function::prelude::*; use shopify_function::Result; #[derive(Deserialize, Default, PartialEq)] pub struct Configuration { threshold: f64, } #[shopify_function] fn cart_fulfillment_constraints_generate_run( input: schema::cart_fulfillment_constraints_generate_run::Input, ) -> Result { // Parse configuration from metafield let config = match input.fulfillment_constraint_rule().metafield() { Some(metafield) => metafield.json_value(), None => &Configuration::default(), }; // Get the cart subtotal and convert threshold to Decimal let subtotal = input.cart().cost().subtotal_amount().amount(); let threshold = Decimal::from(config.threshold); // If the subtotal is below the threshold, prevent splitting if subtotal.lt(&threshold) { let deliverable_line_ids: Vec = input .cart() .deliverable_lines() .iter() .map(|line| line.id().clone()) .collect(); let operations = vec![ schema::Operation::DeliverableLinesMustFulfillFromSameLocationAdd( schema::DeliverableLinesMustFulfillFromSameLocationAddOperation { deliverable_line_ids: Some(deliverable_line_ids), }, ), ]; return Ok(schema::CartFulfillmentConstraintsGenerateRunResult { operations }); } // No constraints if the subtotal is above the threshold Ok(schema::CartFulfillmentConstraintsGenerateRunResult { operations: vec![] }) } ``` ##### Performance Cost (Rust) 33239 instructions ##### Function Code (JavaScript) ```javascript // @ts-check /** * @typedef {import("../generated/api").RunInput} RunInput * @typedef {import("../generated/api").CartFulfillmentConstraintsGenerateRunResult} CartFulfillmentConstraintsGenerateRunResult */ /** * @type {CartFulfillmentConstraintsGenerateRunResult} */ const NO_CHANGES = { operations: [], }; /** * @param {RunInput} input * @returns {CartFulfillmentConstraintsGenerateRunResult} */ export function cartFulfillmentConstraintsGenerateRun(input) { // Parse configuration from metafield const configuration = input.fulfillmentConstraintRule.metafield?.jsonValue ??

Customized constraint types aren't currently supported. *** ## Merchant interface The function's title and description are merchant-facing values, and are rendered as part of the user interface in the [Shopify admin settings](https://admin.shopify.com/settings) under **Shipping and delivery** > **Order routing**. *** ## Additional resources Explore comprehensive guides and references to help you build, deploy, and optimize your Shopify Functions. ### Working with Functions These guides cover essential concepts for building Shopify Functions effectively.
