stripe-payments - 为什么 Stripe checkout Webhooks 将 customer_email 发送到 null？

Question

我尝试在 Checkout Stripe 新界面上付款后获取客户电子邮件。 stripe Webhook 发布的 JSON 总是发送带有 null 值的 customer_email。

stripe Checkout 页面要求提供客户电子邮件，所以我不明白为什么 Stripe 会将此值发送回 null。

虽然，客户值(value)不为空。

客户输入的电子邮件实际上位于 CheckoutSession 链接到的 Customer 对象上。 [0] customer_email 字段是其他字段(您的代码可能已将此字段设置为将电子邮件预填充到 session 中)。

因此，从 API (cus_FoWzBx2yusHfs9) 检索客户对象并检查那里的 email 字段；或检索 Session 对象和 expand the Customer field.
