我知道你可能会问我为什么不先尝试 google 解决方案，现在我可以说我已经用 google 搜索过了，不幸的是它提供了太多的解决方案和不同的方法。
我的情况是这样的，我想让那些客户能够每年订阅我的服务。
来自this link，他们提出了太多的解决方案，我不知道哪一个适合我的情况。当然，我想使用免费服务（直接借记需要月费）。
也就是说，我希望每年在我的客户订阅的服务到期时将交易#存储到我的数据库中，并自动向客户和我公司的电子邮件发送确认电子邮件。
总之，
提前致谢。

您可以使用 PayPal Payments Pro 和 Direct Payment API 来处理初始信用卡交易。然后您可以将交易存储在您的系统中，并将您的系统设置为运行 cron 作业并执行参考交易 API 调用以再次向买家收费。这将为您提供设置定期付款配置文件的效果，而无需通过 PayPal 实际使用该服务。
但是，如果您希望减少编码和设置系统以执行 cron 作业等，那么您可以注册 PayPal 的定期付款/定期计费服务，这样您只需调用 API 即可PayPal 设置个人资料。然后 PayPal 会在您的买家应该付款时向他们收费。
