Orders invoicing with coupons

Validate approved payment

Before consulting the discounts applied to certain order payments, you should check that the payment detail in the order has status: paid, and the payment with status: approved.

When the sale is through a shopping cart, you must remember:

• The pack_order tag is generated automatically to be able to discriminate if the order is associated with a cart and cannot be deleted by the buyer or seller.
• The pack_id field shows the cart number to which the order belongs.

Check discount coupons to invoice

Using the order payment/s, you can check the discount coupons. Check the fee_details node to get the discount value, as long as the fee_payer field equals collector and the type equals coupon_fee.

To get the discount total value on the invoice you must add the amounts with type: coupon_fee.

Order payment example:

curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadopago.com/v1/payments/15733180247
