php - 支付成功后获取交易明细

Question

我正在尝试从 Paypal 取回用户输入的详细信息。

问题 1) 如何从 paypal 获取电子邮件地址和其他详细信息？

Q 2) 系统生成的邮件应该从成功案例发送还是从ipn案例发送？

Q 3) 交易成功后，我在 paypal 屏幕上收到消息 - “我们将向 foo@email.com 发送一封确认电子邮件”。但我根本没有收到任何电子邮件。

注意:我正在沙盒上进行测试。

问题 4) 我没有向买家的地址运送任何元素。那么是否可以从 paypal 屏幕上删除运送地址？

Answer 1

如果没有关于 PayPal 集成的更多信息，无法完整回答，但是:

Q1:PayPal 在 IPN 和大多数相关 API 调用(DoExpressCheckout 等)的响应中提供买家信息。在某些情况下，即使在付款完成之前，它也会有单独的专用调用来获取买家信息(例如 GetExpressCheckout)。在不知道您要集成到哪个支付产品/API 的情况下不能说更多。

Q2:无论卖家是否使用IPN，付款成功后都会发送邮件。 IPN 和电子邮件是独立的功能，彼此无关。

问题 3:沙盒帐户只发送沙盒电子邮件(以防止人们将它们误认为是真正的付款电子邮件)。了解如何在 PayPal 沙盒中查看您的沙盒电子邮件。

问题 4:是的，许多 PayPal 产品都可以做到这一点，但具体情况因您集成的产品而异。例如。您可以在 POST 参数中传递 &shipping=0，或者您可能需要设置 NoShipping=True...阅读您用于设置/将用户重定向到 PayPal 授权流程的特定 PayPal 操作的文档。
