Paypal Rest API與信用卡付款方式

Question

這就是我創建PayPal付款的方式。

 var apiContext = GetApiContext(clientId, clientSecret);

 CreditCard creditCard = new CreditCard();
 creditCard.number = "4877274905927862";
 creditCard.type = "visa";
 creditCard.expire_month = 11;
 creditCard.expire_year = 2018;
 creditCard.cvv2 = "874";
 creditCard.first_name = firstName;
 creditCard.last_name = lastName;

 Amount amount = new Amount();
 amount.total = "7.47";
 amount.currency = "USD";

 Transaction transaction = new Transaction();
 transaction.amount = amount;
 transaction.description = "This is the payment transaction description.";

 List<Transaction> transactions = new List<Transaction>();
 transactions.Add(transaction);

 FundingInstrument fundingInstrument = new FundingInstrument();
 fundingInstrument.credit_card = creditCard;

 List<FundingInstrument> fundingInstruments = new List<FundingInstrument>();
 fundingInstruments.Add(fundingInstrument);

 Payer payer = new Payer();
 payer.funding_instruments = fundingInstruments;
 payer.payment_method = "credit_card";

 Payment payment = new Payment();
 payment.intent = "sale";
 payment.payer = payer;
 payment.transactions = transactions;

 Payment createdPayment = payment.Create(apiContext);

對於payment.execute，我需要付款ID和付款人ID。 但付款人ID變為空你能告訴我，我怎樣才能獲得付款人ID？ 我錯過了什么嗎？

Answer 1

您無需payment.Execute(...)當您使用信用卡付款時，請執行payment.Execute(...) 。

創建付款后...

Payment createdPayment = payment.Create(apiContext);

...，只需調用createdPayment.id即可獲取付款ID。

如果想通過paypal方法payment.Create(...) ，則需要payment.Create(...) ，然后payment.Execute(...) （在買方通過重定向到PayPal批准付款后）。

關於付款人ID

當您使用paypal方法payment.Create(...) ，您會進行payment.Create(...)然后將買方重定向到PayPal。 在買家批准付款后，PayPal會重定向到您的網址，並在查詢字符串中為您提供PayerID 。 然后，您將執行以下付款：

var execution = new PaymentExecution { payer_id = Request.Params["PayerID"] };
payment.Execute(apiContext, execution);

請參考Paypal pro API。 我認為這對你有好處，並為你提供更好的知識。
