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，我使用的是检查订阅的 cron每日
问题是我们错过了一个订阅，如果它不能在应该收费的日期收费。有时，由于账户中没有资金或卡发生任何原因导致延迟几天，客户卡无法扣款。
我想知道何时在 chargify 中收取客户卡，以便那时我可以生成新订单，我已经使用了上述 PHP 库，但找不到可以获取我信息的函数。
任何人都可以为此提供帮助或任何其他解决方案来解决此问题吗？
谢谢
Chargify 有一个特殊的功能，称为“Webhooks”（就像 Paypal、Stripe 等）。每当客户的订阅有活动（如每月续订）时，Chargify 都会直接向您的服务器发送一个 POST 请求以提醒您。
具体文档在这里：https ://docs.chargify.io/webhooks
不需要 cron 工作！
您可以通过 webhook 设置并在客户收费后立即获取所有信息，为此您需要在您的服务器上设置 webhook url，然后将其添加到 chargify 帐户，登录后转到 Settings -> Webhooks -> Add url 例如：
http://www.domain.com/webhooks/
在“webhooks”目录下创建 index.php 文件，你会从 chargify 得到一个数组，如下所示：

我希望这有帮助。
最简单的方法是将最后一次成功的交易日期存储在数据库中，并经常检查自上次使用 cron 或 mysql 事件调度程序更新以来是否已过去一个月，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来更新数据库
