Shopify Admin API GraphQL Nested Query

[henrytran721]

Hello! I have a query here for DiscountCode and I want to filter by `createdBy` an external app. I want to retrieve all DiscountCodes that have not been created by an external app however, I'd like to do this query at the top level to return them. Is this possible in this API? Thank you. 

{
  discountNodes(first: 19, query: "status:active", reverse: true) {
    edges {
      node {
        id
        discount {
          ... on DiscountCodeBasic {
            title
            status
            codes(first: 1) {
              edges {
                node {
                  code
                  createdBy {
                    id
                    title
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}

Hi , there

 Appears that there is no direct method to filter DiscountCodes based on the createdBy field. However, you can retrieve all the discount codes through a query and then apply manual filtering in your program logic.  what do you think?
