问题描述
当有人开始定期订阅时，我会传递 custom 变量，该变量包含我系统上用户的用户 ID.付款后，我收到两个 IPN，subscr_signup 和 subscr_payment.两者都有自定义变量，可以让我识别用户.
When someone starts a recurring subscription, i pass on the custom variable which contains the User ID of the user on my system. After the payment I receive two IPNs, subscr_signup and subscr_payment. Both have the custom variable in them which lets me identify the user.
但是，对于未来的定期付款，IPN 会继续传递自定义变量吗?我应该依赖 subscr_id 而不是自定义吗?
However, for future recurring payments, will the IPN continue to pass on the custom variable? Should I rely on the subscr_id instead of custom?
谢谢.
推荐答案
我从 此页面.是的，自定义变量将始终在每个连续的 IPN 帖子中按原样传递.
I found the answer from this page. Yes, the custom variable will always be passed as-is in every consecutive IPN post.
引用:
自定义通过注册和支付 IPN 帖子传递回来，并通过连续的 IPN 帖子传递回来.没有一个变量在第一个支付 IPN 中传回，而不是在连续的支付中重现.唯一可区分的因素是注册或第一期付款的价格是否不同.
