Good morning to everyone.
I am doing a study to integrate PayPal into a major ecommerce site.
The site is in Java J2EE platform and to make my tests I have done so a small java application that simulates the payment by calling the various API PayPal / Sandbox.
I use the protocol NVP and the flow is this:
SetExpressCheckout - Sale type
DoExpressCheckoutPayment - Sale type
At this point I try to make a refund with the command RefundTransaction, but PayPal accepts only REFUNDTYPE Full, Partial type is not accepted and I receive the code 1009.
Can you tell me if you can make a partial refund in this case?
Thank you.
