Discount application information now available for draft orders on the Customer Account API

As of GraphQL Customer Account API version 2026-07, draft orders now expose discount applications.

You can use the new discountApplications field on DraftOrder to query discounts applied to a draft order, and the new discountAllocations field on DraftOrderLineItem to query how discounts are allocated across line items.

For example:

  query DraftOrderDiscounts($id: ID!) {
    draftOrder(id: $id) {
      discountApplications(first: 10) {
        nodes {
          __typename
          ... on DiscountCodeApplication {
            code
          }
          ... on ManualDiscountApplication {
            title
          }
          allocationMethod
          targetSelection
          targetType
          value {
            ... on MoneyV2 {
              amount
              currencyCode
            }
            ... on PricingPercentageValue {
              percentage
            }
          }
        }
      }
      lineItems(first: 10) {
        nodes {
          title
          discountAllocations {
            allocatedAmount {
              amount
              currencyCode
            }
            discountApplication {
              __typename
            }
          }
        }
      }
    }
  }

Use these fields to understand which discounts apply to a draft order and how those discounts affect individual draft order line items.
