Discount Representations in the Get Shipment Packages Service

Understanding Order Discounts

Discount fields in the getShipmentPackages service — which discounts are seller-funded, which are Trendyol-funded, and how to read them.

Key Rule: lineItemSellerDiscount represents the discount covered by the seller, while lineItemTyDiscount represents the discount covered by Trendyol. The two are completely independent.

Net unit price: lineItemPrice = lineGrossAmount − lineItemSellerDiscount − lineItemTyDiscount

Field Hierarchy

Package Level

Summarizes the entire order.

Field	Description
`packageGrossAmount`	Total gross amount (before discounts)
`packageSellerDiscount`	Total seller discount
`packageTyDiscount`	Total Trendyol discount *
`packageTotalDiscount`	Total discount (Seller + TY)
`packageTotalPrice`	Net amount payable
`discountDisplays[]`	Campaign names and discount amounts

* packageTyDiscount may be populated only for commercial=true (B2B) orders.

Line Level — `lines[]`

Per-product unit totals.

Field	Description
`lineGrossAmount`	Unit gross price (before discounts)
`lineSellerDiscount`	Seller discount (sum of items)
`lineTyDiscount`	TY discount (sum of items)
`lineTotalDiscount`	Total unit discount
`lineUnitPrice`	Net unit price

Item Level — `discountDetails[]`

Separate discount entry per unit. For a line with quantity=N, discountDetails returns an array of N elements.

Field	Description

`lineItemSellerDiscount`	Seller discount applied to this item
`lineItemTyDiscount`	Trendyol discount applied to this item

}

        }
      ]
    }
  ]
}

3. Trendyol Coupon

  "packageSellerDiscount": 0.00,
  "packageTyDiscount": 75.00,
  "packageTotalDiscount": 75.00,
  "packageTotalPrice": 425.00,

          "lineItemTyDiscount": 75.00
        }
      ]
    }
  ]
}

4. Trendyol Campaign (Flash Sale / Deals)

A platform-wide campaign organized by Trendyol such as Flash Sale, Deals, or "20% Off in Cart". The full discount is funded by Trendyol.

  "packageSellerDiscount": 0.00,
  "packageTyDiscount": 160.00,
  "packageTotalDiscount": 160.00,
  "packageTotalPrice": 640.00,
  "discountDisplays": [
    {
      "displayName": "20% Off in Cart",

      "lineSellerDiscount": 0.00,
      "lineTyDiscount": 160.00,

          "lineItemTyDiscount": 160.00
        }
      ]
    }
  ]
}

5. Combined Discount (Seller + Trendyol)

When a seller campaign and a Trendyol coupon are both applied to the same order, both fields are populated.

{
  "packageGrossAmount": 600.00,
  "packageSellerDiscount": 60.00,
  "packageTyDiscount": 50.00,
  "packageTotalDiscount": 110.00,
  "packageTotalPrice": 490.00,
  "discountDisplays": [
    {
      "displayName": "10% Seller Discount",
      "discountAmount": 60.00
    },
    {
      "displayName": "50 TL Coupon",
      "discountAmount": 50.00
    }
  ],
  "lines": [
    {
      "lineGrossAmount": 600.00,
      "lineSellerDiscount": 60.00,
      "lineTyDiscount": 50.00,
      "lineTotalDiscount": 110.00,
      "lineUnitPrice": 490.00,
      "discountDetails": [
        {
          "lineItemPrice": 490.00,
          "lineItemSellerDiscount": 60.00,
          "lineItemTyDiscount": 50.00
        }
      ]
    }
  ]
}

6. Multiple Quantities (quantity > 1)

When 2 units of the same product are ordered, discountDetails returns a separate entry for each unit. lineSellerDiscount is the sum of all items in that line.

{
  "packageGrossAmount": 700.00,
  "packageSellerDiscount": 70.00,
  "packageTyDiscount": 0.00,
  "packageTotalDiscount": 70.00,
  "packageTotalPrice": 630.00,
  "discountDisplays": [
    {
      "displayName": "10% Seller Discount",
      "discountAmount": 70.00
    }
  ],
  "lines": [
    {
      "quantity": 2,
      "lineGrossAmount": 350.00,
      "lineSellerDiscount": 35.00,
      "lineTyDiscount": 0.00,
      "lineTotalDiscount": 35.00,
      "lineUnitPrice": 315.00,
      "discountDetails": [
        {
          "lineItemPrice": 315.00,
          "lineItemSellerDiscount": 35.00,
          "lineItemTyDiscount": 0.00
        },
        {
          "lineItemPrice": 315.00,
          "lineItemSellerDiscount": 35.00,
          "lineItemTyDiscount": 0.00
        }
      ]
    }
  ]
}
