Discounts are reported as additional line items, where you can either apply the discount to a specific item, or to the whole invoice (see reference_number parameter below). If the discount applies to the entire invoice, you can omit the reference_number parameter.
Discounts need to have a parameter “type” put to “Discount” in the line item details.
In the below example, we reported a transaction with 2 line items related to the sale, and a discount was applied to the 2nd line item.
Discount items should have negative signs next to unit_price, net_price, and tax_amount.
