Question

我正在构建一个涉及paypal订阅的asp.net网络应用程序。我需要检查用户是否已经取消登录这是否可能，如果是这样，怎么办？我已经看过关于这个主题的其他帖子但我的情况有所不同，因为我要检查登录。我想也许我可以每晚从paypal进行批量数据转储，并检查是否在取消的用户上设置了一个标志。不知道最好的方法是做什么..

Answer 1

如果您想在登录PayPal后检查用户是否已接受或取消协议，则可以使用快速结账令牌进行检查。在买方登录PayPal帐户并在响应中查找变量 BILLINGAGREEMENTACCEPTEDSTATUS 后，您需要在令牌上调用 GetExpressCheckoutDetails API。

BILLINGAGREEMENTACCEPTEDSTATUS = 0表示买家在登录PayPal帐户后未接受协议 或点击取消。

BILLINGAGREEMENTACCEPTEDSTATUS = 1，表示在登录PayPal后点击了“同意并继续”。

我已经包含了一些样本回复。
