title: Adding a discount amount to payment request to PAYPAL through REST API
body: <p>I am using PAYPAL Rest API for payment transaction. I am calling context(/v1/payments/payment) for authorization and passing the ItemList as part of Transaction object.</p>
  
  <p>Requirement: To Display Discount/GiftCard amount as part of the ItemList on the Paypal authentication page.</p>
  
  <p>Problem: The API doesn't allow to put negative amount to an item and validation error is thrown.</p>
  
  <p>Can anyone tell me if it is possible to display discount/gift card negative amount. (It is possible in Classic API though)</p>
