[英]PayPal IPN not working
I'm setting up so that my customers can subscribe for x amount a month for a service. 我正在进行设置,以便我的客户可以每月订阅x金额的服务。
When a payment is made, everything is fine. 付款后,一切都很好。 But it seems that when somebody cancels a subscription it still goes through as a completed payment.
但是似乎当有人取消订阅时,它仍会作为完成的付款进行。
Any help would be greatly appreciated. 任何帮助将不胜感激。

There are different transaction types possible with PayPal IPN. PayPal IPN可能有不同的交易类型。 See here: https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNandPDTVariables/
参见此处: https : //developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNandPDTVariables/
Typically, your back-end or administrative processes will perform specific actions based on the kind of IPN message received.
通常,您的后端或管理过程将根据收到的IPN消息的种类执行特定的操作。 You can use the txn_type variable in the message to trigger the kind of processing you want to perform.
您可以在消息中使用txn_type变量来触发要执行的处理类型。
It sounds like you are simply assuming the transaction type is a payment, but you are, in fact, getting an incomplete or canceled payment notification. 听起来您只是在假设交易类型为付款,但实际上您收到的付款通知不完整或已取消。
