我试图让用户从paypal返回详细信息。
问1）如何从paypal获取电子邮件地址和其他详细信息？
问2）系统生成的邮件应该是从成功案例还是从ipn案例发送的？
问3）成功交易后，我在paypal屏幕上收到消息 - '我们会向foo@email.com发送确认电子邮件'。但我根本没有收到任何电子邮件。
注意：我正在测试沙盒。
问4）我没有将任何商品运送到买家的地址。那么是否可以从paypal屏幕删除送货地址？

答案 0 :(得分：0)
如果没有关于PayPal集成的更多信息，则无法完全回答，但是：
Q1：PayPal向买家提供有关IPN和大多数相关API调用（DoExpressCheckout等）的回复信息。在某些情况下，它甚至在付款完成之前就有单独的专用电话来获取买家信息（例如GetExpressCheckout）。如果不知道您正在整合哪种支付产品/ API，就无法说出更多信息。
Q2：无论卖家是否使用IPN，都会在成功付款后发送电子邮件。 IPN和电子邮件是不同的功能，彼此无关。
问题3：沙盒帐户仅发送沙盒电子邮件（以防止人们将其误认为是真正的付款电子邮件）。查看如何在PayPal沙箱中查看沙箱电子邮件。
问题4：是的，许多PayPal产品都可以实现这一点，但具体情况因您所使用的产品而异。例如。您可以在POST参数中传递＆amp; shipping = 0，或者您可能需要设置NoShipping = True ...读取您用于设置/将用户重定向到PayPal授权流程的特定PayPal操作的文档。
