Question

如何在Paypal中使用Paypal的两个功能 - SetExpressCheckoutPaymentAuthorization和Chained Payment。我想授权买家和卖家。当买家付款时，它将在交易完成时保持为paypal，然后付款进入卖家账户，20％的金额将进入管理员账户，80％的进入卖家账户使用Paypal。请逐步了解此过程。我想在我的asp.net项目中实现这个过程。

您可以在自适应付款中使用PreApproval的概念，您可以在将来的任何时间获得买方的许可，并且一旦他同意您将获得可在您的自适应链支付API中使用的预批准密钥致电支付给主要和次要接收者的付款。通过这种方式，买家不会立即收取费用，您将有足够的时间进行支付。

Flow将是这样的：

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.timestamp=2014-10-18T14:31:26.577-07:00
responseEnvelope.ack=Success
responseEnvelope.correlationId=51317322d3c7d
responseEnvelope.build=13085071
preapprovalKey=PA-6D174595N6325214K

2.将买家转到PayPal页面同意：

https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-preapproval&preapprovalkey=PA-6D174595N6325214K

3.使用上面收到的PreApproval Key向买家提供以下信息：

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
