PayPal Rest API-使用更新的交易信息执行支付

Question

我正在使用C#和PayPal Rest API来获得一个批准的支付并执行它。但是，我需要更新与批准的付款相关联的交易记录。PayPal文档中写道：

//Update the payment details in case totals changed because of a new address/zipcode
Details amountDetails = new Details();
amountDetails.subtotal = ValidationHelper.GetString(prices[Order.CartPricesEnum.Subtotal], "0");
amountDetails.tax = ValidationHelper.GetString(prices[Order.CartPricesEnum.Tax], "0");
amountDetails.shipping = ValidationHelper.GetString(prices[Order.CartPricesEnum.Shipping], "0");

Amount amount = new Amount();
amount.total = ValidationHelper.GetString(prices[Order.CartPricesEnum.Total], "0");
amount.currency = "USD";
amount.details = amountDetails;

//update the transaction to make sure we have accounted for any updated prices
Transactions trn = new Transactions();
trn.amount = amount;

List<Transactions> trns = new List<Transactions>();                    
trns.Add(trn);

//Create a payment execution object
PaymentExecution paymentExecution = new PaymentExecution();
paymentExecution.payer_id = payPalPayerID;
paymentExecution.transactions = trns;                    

//Execute (complete) the payment
Payment newPayment = payment.Execute(accessToken, paymentExecution);

{"name":"VALIDATION_ERROR","details":[{"field":"transactions[0].total","issue":"Required field missing"},{"field":"transactions[0].currency","issue":"Required field missing"},{"field":"transactions[0].amount","issue":"This field name is not defined for this resource type"}],"message":"Invalid request - see details","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#VALIDATION_ERROR","debug_id":"bcba38f3c56d7"}

transactions    
array of transaction objects    
Transactional details if updating a payment. Note that this instance of the transactions object accepts only the amount object.

看起来paymentExecution transactions对象只接受amount对象而不接受transaction对象。
