Chargify有一个特别的功能，叫做"Webhooks"(就像Paypal、Stripe等(。每当客户的订阅有活动时(比如每月续订(，Chargify都会直接向您的服务器发送POST请求，提醒您注意。
我正在使用Chargify API(https://github.com/jforrest/Chargify-PHP-Client/)，我们有成千上万的客户每月订阅，所以他们在特定日期收费，我使用的是每天检查订阅的cron
问题是，如果订阅不能在本应收费的日期收费，我们就会错过订阅。有一段时间，由于账户中没有资金，或者他们的卡出现了任何原因，导致延迟几天，客户卡无法收费。
我想知道什么时候客户卡在chargify中收费，这样我就可以生成一个新的订单，我已经使用了上面的PHP库，但找不到一个函数来获取我的信息。
有人能帮助解决这个问题吗？或者有其他解决方案可以解决这个问题？
感谢
具体文档如下：https://docs.chargify.io/webhooks
不需要cron作业！
您可以通过webhook进行设置，并在客户收费后立即获得所有信息，为此，您需要在服务器上设置webhook url，然后将其添加到chargify帐户，登录后转到设置->webhook->添加url，例如：
http://www.domain.com/webhooks/
在"webhooks"目录下创建index.php文件，您将从chargify获得一个数组，如下所示：

我希望这能有所帮助。
最简单的方法是将上次成功的交易日期存储在数据库中，并经常使用cron或mysql事件调度程序检查自上次更新以来是否已经过去了一个月，从未使用过chargify，但paypal api可以与您的服务器通信并返回交易状态，您可以在您的网站上使用它来更新数据库
