Paypal定期付款IPN

Question

我在Paypal内部设置了一个IPN，每次使用Payflow Pro进行定期付款时都会打到。 如何让它发回我需要的自定义ID的变量，以确保我可以用来扩展成员资格？

到目前为止，我已经尝试过ProfileID，payer_business_name，option_name1，rp_invoice_id，invoice和custom，当它通过时都没有发回。

Answer 1

如果custom变量包含在POST中，它应该可以正常工作。 或者，您可以将任何您喜欢的变量name = value对添加到notify_url，只要它们不与PayPal的IPN变量冲突即可。

Answer 2

rp_invoice_id在recurring_payments_profile_created和regular recurring_payment IPN中都返回。 这是两者的样本。

如果您的IPN中没有获得rp_invoice_id，那么它必须无法正确地包含在您的API请求中。
