--- title: Order Discount Function API (deprecated) description: >- Use the Order Discount Function API to create a new type of discount that's applied to an order. api_version: 2026-10 source_url: html: 'https://shopify.dev/docs/api/functions/latest/order-discount' md: 'https://shopify.dev/docs/api/functions/latest/order-discount.md' api_type: functions api_name: order-discount --- # Order Discount Function API (deprecated) **Deprecated:** This is a deprecated API. You should migrate to the [Discount Function API](https://shopify.dev/docs/api/functions/latest/discount#product-discount-function-api-and-order-discount-function-api), which provides a unified schema for creating discount function extensions. [Order discounts](https://shopify.dev/docs/apps/build/discounts#discount-classes) are discounts that apply to the entire order rather than individual products. You can provide a percentage off or a fixed amount off the total order value, and create custom rules for when these discounts apply, such as minimum purchase requirements or customer eligibility. Order discounts can be [combined with other discount classes](https://help.shopify.com/manual/discounts/discount-combinations) under certain conditions. To create a new type of discount that's applied to an order, and isn't [offered out of the box by Shopify](https://help.shopify.com/manual/discounts/discount-types), you can only use the Order Discount API. [Shopify Functions](https://shopify.dev/docs/api/functions/current) enable you to customize Shopify's backend logic. The Order Discount API integrates this logic into the checkout flow. Use the API to create custom order discount functionality, based on data like buyer identity, cost, and delivery groups. ### Use cases * Offer a discount on the order subtotal. * Offer a discount on products in an order. * Offer a tiered discount by spending, such as spend $100 and get 10% off all products. * Offer a special discount to customers based on metadata, like giving an additional 15% off to "Gold Members" of a loyalty program. ## Function target Checkout ### Compatibility with Shopify surfaces Supported (7) Partially supported (2) Unsupported (5) * [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): Not supported * [Draft Order (Admin)](https://shopify.dev/docs/apps/build/b2b/draft-orders): Partially supported This option is disabled by default. * [Draft Order (Checkout)](https://shopify.dev/docs/apps/build/b2b/draft-orders): Partially supported This option is disabled by default. * [Order Edit (Admin)](https://shopify.dev/docs/apps/build/orders-fulfillment/order-management-apps/edit-orders): Not supported * [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): Supported * [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/): Supported * [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): Not 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/2026-10#configuration) to customize the way your function operates. ## Terminal ```terminal shopify app generate extension --template order_discounts ``` *** ## 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 `purchase.order-discount.run` The run target applies discounts to an order, using Shopify data or hardcoded values. The target returns a list of discounts and strategies to be applied to products in an order. For example, you might use this to offer a 20% discount on all products on the order. * Input OBJECT The `Input` object is the complete GraphQL schema that your function can query as input to customize discounts. Your function receives only the fields that you request in the input query.

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. * 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.

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.
