如何链接PayPal网络钩子和用户

Question

我想我在这里看起来非常简单。

当我通过PayPal PHP SDK 创建新的计费协议时，我通过以下 URL 返回到我的商店。

/paypal-success?success=true&token=EC-3K353628LH3197445  

我已经为 Subscription Created 事件创建了一个发布 JSON 的WebHook，如下所示

将用户重定向回我的商店时生成的令牌似乎不在WebHooks JSON 中。

一旦PayPal用户被重定向回您的商店，您将如何链接他们到传入的WebHooks？

Answer 1

成功 URL 中返回的令牌用于在用户接受协议后激活协议PayPal。 激活协议后，可以检索协议 ID。 该 id 位于资源/id 下的 Web 挂钩中。 "id"： "I-55KA5N9GPPJW"。 可能有更好的方法来解决这个问题，但我创建了一个将协议 ID 与用户 ID 相关联的订阅表，以及一个包含协议 ID 和关联的 Webhook 信息的事务表。
