Once we have processed your request, you will also receive a REFUND webhook.\nApply a discount\nThere are several ways to apply a discount to the invoice:\n\nApply a discount to individual line items.\nApply a discount to the whole purchase.\nLet Adyen add a discount line for you. This is the fallback option in case the other methods do not work for you.\n\nThe examples below apply a 30% discount to the shopper's basket, which contains:\n\nOne pair of shoes, original price EUR 12.00 including 20% VAT\nTwo pairs of socks, original price EUR 4.50 including 20% VAT\n\nApply a discount to individual line items\nWith this method of applying a discount, you reduce the cost of the applicable line items instead of discounting the basket as a whole. To apply a discount to individual line items:\n\nCalculate the reduced amount of each line item you want to discount.\nSend a payment request in which each line item specifies the discounted amounts:\n\namountExcludingTax\ntaxAmount\namountIncludingTax\n\n\n\n Sample basket with discounts applied to individual items\n \n \n Product\n Quantity\n Item Price (EUR)\n VAT (EUR)\n Total price (EUR)\n \n \n \n \n Shoes (with 30% discount)\n 1\n 7,00\n 1,40\n 8,40\n \n \n Socks (with 30% discount)\n 2\n 2,63\n 0,52\n 6,30\n \n \n Purchase amount\n 12,26\n \n \n VAT\n 2,44\n \n \n TOTAL\n 14,70\n \n \n\n\n \n\nApply a discount to the whole purchase\nWith this method of applying a discount, you specify the line items with their original price and then apply a discount to the basket as a whole by adding a discount line.\nTo apply a discount to the entire basket:\n\nCalculate the discount to the product total and the VAT.\nIn your payments request, send each fully priced line item, plus a line Item to specify the discount with the following parameters:\n\nid: Discount\ndescription: Discount\namountExcludingTax: The discount amount, preceded by a minus sign\ntaxAmount: The discount amount, preceded by a minus sign\namountIncludingTax: The discount amount, preceded by a minus sign\n\n\n\n Sample basket with a discount applied to the entire basket\n \n \n Product\n Quantity\n Item Price (EUR)\n VAT (EUR)\n Total price (EUR)\n \n \n \n \n Shoes\n 1\n 10,00\n 2,00\n 12,00\n \n \n Socks\n 2\n 3,75\n 0,75\n 9,00\n \n \n Total before discount\n 21,00\n \n \n Product discount\n 5,25\n \n \n VAT discount\n 1,05\n \n \n Total discount (30%)\n 6,30\n \n \n TOTAL\n 14,70\n \n \n\n\n \n\nLet Adyen add a discount line for you\nWith this method of applying a discount, Adyen calculates that amount.value is less than the total value of the line items, so a discount must have been applied. In this case, Adyen adds a line item for the discount before sending to Klarna.\n\n \n\nAdjust an authorization\nIf you want to adjust an authorized payment that has not yet been fully captured, your API request must specify all captured and refunded lineItems. See Adjust an authorization for detailed instructions. This is available for Klarna with Checkout API v70 and later.\nBelow are two examples of adjusting an authorized payment:\n\nCancel part of the authorization before capture\nAdd a new product to a partially captured order\n\nThese examples are based on the following order:\n\n \n\nCancel part of the authorization before capture\nIf you want to cancel or adjust the authorization before capturing, you can declare the new amount and associated lineitems.\nThe following example removes Item #2 from the above order by declaring the new basket composition and amount.\n\n \n\nAdd a product from a partially captured order\nIf you want to add products to a partially captured or refunded order, you must include the already captured or refunded lineItems in the update request, in addition to the new order content.\nIn the following example, Item #1 from the above order is captured, and we add a third item to the order:\n\n \n","type":"page","locale":"pt","boost":17,"hierarchy":{"lvl0":"Home","lvl1":"Payment methods","lvl2":"Klarna","lvl3":"Specifying invoice lines and discounts"},"hierarchy_url":{"lvl0":"https:\/\/docs.adyen.com\/pt","lvl1":"https:\/\/docs.adyen.com\/pt\/payment-methods","lvl2":"https:\/\/docs.adyen.com\/pt\/payment-methods\/klarna","lvl3":"\/pt\/payment-methods\/klarna\/invoice-lines"},"levels":4,"category":"Payment method","category_color":"green","tags":["Specifying","invoice","lines","discounts"]},"articleFiles":{"basket.png":"![\"\"](\"https:\/\/docs.adyen.com\/user\/pages\/docs\/08.payment-methods\/42.klarna\/12.invoice-lines\/basket.png\")
