I am using .net SDK to create a refund in the sandbox. The order that I am trying to do the refund on has been created also in the sandbox. And is there in the dashboard.
I am getting an error of “The payment XXXXXXXXXXXX can’t be processed through this API.”
I have tried every unique ID I have, and I must be using the correct payment_id as all the others give me an error of “Could not find payment with id: 123456”
I am getting the same errors when using the API explorer.
