验证两个第三方之间的PayPal捐赠 [英] Verify PayPal donation between two 3rd parties

问题描述

我正在开展一个项目，允许用户互相捐款。

I'm working on a project where users will be allowed to send donations among each other.

我想将它与Paypal集成而不是重新发明轮子和建立我自己的捐赠系统，但由于系统的性质，我需要验证从A人到B人的X美元捐赠。

I'd like to integrate it with Paypal instead of reinventing the wheel and building my own donation system, but due to the nature of the system, I will need to verify that a donation of X dollars was sent from person A to person B.

这可能与Paypal有关，还是我运气不好？

Is this possible with Paypal, or am I out of luck?

推荐答案

你需要看看 PayPal即时付款通知（IPN）。

在致电PayPal处理捐赠/付款，您可以指定监听器的URL，这是PayPal将与付款详细信息联系的脚本，然后可以针对PayPal验证该付款以确保其准确/已确认/未伪造。

Within the call to PayPal to handle the donation/payment, you can specify the URL for a "Listener", which is a script which will be contacted by PayPal with details on the payment, and can then authenticate that payment against PayPal to ensure that it is accurate/confirmed/not faked.

在传回监听器的数据中，是付款人的电子邮件地址和收款人，已付金额，收费等等。

Within the data passed back to the Listener is the email addresses of the Payer and the Payee, along with the amount paid, fees charged, etc.

如果您是双方的中间人，并且只要通过付款方式付款您控制的表单/网站，然后您应该能够使用IPN获取这些付款的详细信息，然后按照您的意愿使用该数据。

If you are acting as an intermediary to the two parties, and so long as the payment are made through the form/site you control, then you should be able to use the IPN to get details of those payments and then use that data however you wish to.
