我遇到了Paypal定期付款的问题。 CreateRecurringPaymentsProfile（）返回已创建的配置文件（ProfileID）的ID。同时，我在IPN网址上收到以下确认信息：
payment_cycle - Daily
txn_type - recurring_payment_profile_
created
last_name - User
next_payment_date - 03:00:00 Oct 06, 2011 PDT
residence_country - US
initial_payment_amount - 0.00
currency_code - USD
time_created - 23:21:02 Oct 05, 2011 PDT
verify_sign - ...
period_type - Regular
payer_status - verified
test_ipn - 1

outstanding_balance - 0.00
---------->recurring_payment_id - I-6EFKVB5FXRGH

显然，ProfileID和recurring_payment_id是相等的。在此之后，收到有关付款的确认信息：
mc_gross - 20.00
outstanding_balance - 0.00
period_type - Regular
next_payment_date - 03:00:00 Oct 07, 2011 PDT

这三个值：ProfileID以返回CreateRecurringPaymentsProfile（）; recurring_payment_profile_created中的recurring_payment_id; recurring_payment中的recurring_payment_id应该是相同的。 （因为似乎没有其他方法可以正确识别此特定订阅的付款） 此外，每次recurring_payment_id不同时，Paypal会多次发送recurring_payment（在IPN上）。
我应该使用recurring_payment_id来确定特定订阅的付款方式，还是有另一种正确的方式来识别它？
答案 0 :(得分：8)
个人资料ID = recurring_payment_id。如果recurring_payment_id不同，我们会讨论不同的ProfileID（换句话说：不同的定期付款资料）。
