Unable to Set LineItemDiscount on OrderCreateLineItemInput

GraphQL Admin API Troubleshooting
1

I want to create a discount that applies only to a specific LineItem, but OrderLineItem does not have a field to represent this.

Hi Shota,

Have you tried using the orderEditAddLineItemDiscount mutation? It allows you to specify a lineItemId and a discount. It would look something like this:

mutation AddLineItemDiscount {
  orderEditAddLineItemDiscount(
    discount: {
      description: "10% off specific item",
      percentValue: 10.0
    },
    id: "gid://shopify/OrderEdit/1234567890",
    lineItemId: "gid://shopify/LineItem/0987654321"
  ) {
    addedDiscountStagedChange {
      description
      id
      value {
        ... on PricingPercentageValue {
          percentage
        }
      }
    }
    calculatedLineItem {
      id
      title
      discountedUnitPriceSet {
        presentmentMoney {
          amount
          currencyCode
        }
      }
    }
    userErrors {
      field
      message
    }
  }
}

Hi Liam,

I didn’t know that. Thanks for telling me! But I hope it will be possible to achieve this with just orderCreate.
