How can I retrieve discount details from an order using GraphQL?

[JackL]

I have a discount that applied in a order and it showing this details in the order detail in admin panel

I was trying to retrieve this detail from the graphql, the following is the approach I made

        query ($numProducts: Int!, $cursor: String, $query: String!) {
          orders(first: $numProducts, after: $cursor, query: $query) {
            edges {
              node {
                createdAt
                lineItems(first: 20) {
                  nodes {
                    id
                  }
                }
              }
            }
            pageInfo {
              hasNextPage
              endCursor
            }
          }
        }

I not sure how do I get it from graphql, do anyone have idea?

The `order` object includes connections to (order-level) `discountApplications` and `lineItems`. I'm not sure where the information you highlighted in the screen capture came from, but the following query shows how you can retrieve both the order-level and lineitem-level discount allocations.

{
  "query": "
query getOrder($orderId: ID!) {
  order(id: $orderId) {
    id customer { id } discountCodes
    discountApplications(first: 5) { edges { node {
      ...discountApplicationFields
    } } }
    lineItems(first: 50) { edges { node {
      id quantity currentQuantity name sku
      discountAllocations {
        allocatedAmountSet { shopMoney { amount currencyCode } }
        discountApplication { ...discountApplicationFields }
      }
    } } }
  }
}

fragment discountApplicationFields on DiscountApplication {
  index
  allocationMethod
  targetType
  value {
    __typename
    ... on MoneyV2 { amount currencyCode }
    ... on PricingPercentageValue { percentage }
  }
}
",
"variables":{"orderId":"gid://shopify/Order/12345"}
}

 The response will be like:
