在asp.net中使用paypal進行授權後進行連鎖支付

Question

如何使用Paypal的SetExpressCheckoutPaymentAuthorization和PayPal支付功能。我想授權買方和賣方。當買家付款時，交易完成後，付款將保持不變，然後付款到賣家帳戶，20％的金額將進入管理帳戶，80％的賣家帳戶使用PayPal。請逐步瞭解這一過程。我想在我的asp.net項目中實現這個過程。

Answer 1

可以使用預先批准的概念，自適應支付在那裏你可以從買方獲得許可，在未來任何時候給他充電，一旦他同意你會得到你可以在你的自適應鏈支付使用預準關鍵API調用將付款分配給Primary和Secondary Receiver。通過這種方式，買方不會立即收取費用，而且您將有足夠的時間進行支付。

流將是這樣的：

1.Preapproval：

NVP Request: 
requestEnvelope.errorLanguage=en_US&startingDate=2014-10-19Z&endingDate=2015-10-19Z¤cyCode=USD&cancelUrl=XXXXXXX&returnUrl=XXXXXX&ipnNotificationUrl=XXXXXXXX&maxAmountPerPayment=10.00&maxNumberOfPayments=50&maxNumberOfPaymentsPerPeriod=10&maxTotalAmountOfAllPayments=500.00&memo=This is Preapproval memo&paymentPeriod=DAILY 

NVP Response:

responseEnvelope.ack=Success 
responseEnvelope.correlationId=51317322d3c7d 
responseEnvelope.build=13085071 
preapprovalKey=PA-6D174595N6325214K 

2.Redirect買家到PayPal頁面同意它：

3.充電買家在稍後的時間使用上面收到的PreApproval密鑰：

NVP Request: 
actionType=PAY&requestEnvelope.errorLanguage=en_US&cancelUrl=XXXXX&returnUrl=XXXXXX&ipnNotificationUrl=XXXXXX&applicationId=XXXXXXX&memo=Chain Payment via PreApproval¤cyCode=USD&receiverList.receiver(0).email=XXXXX.co.in&receiverList.receiver(0).amount=5.00&receiverList.receiver(0).primary=true&receiverList.receiver(1).email=EXXXXX.co.in.pro&receiverList.receiver(1).amount=2.00&receiverList.receiver(1).primary=false&feesPayer=EACHRECEIVER&preapprovalKey=PA-6D174595N6325214K&pin=123456&detailLevel.DetailLevelCode=ReturnAll
