### 跟踪支付事件

```javascript track_payments.js icon="js" expandable theme={null}
function handler(webhook) {
  if (webhook.eventType === "payment.succeeded") {
    const p = webhook.payload.data;
    webhook.url = "https://track.customer.io/api/v2/entity";
    webhook.payload = {
      type: "person",
      identifiers: {
        id: p.customer.customer_id
      },
      action: "payment_completed",
      name: "Payment Completed",
      attributes: {
        email: p.customer.email,
        name: p.customer.name,
        payment_amount: (p.total_amount / 100).toFixed(2),
        payment_method: p.payment_method || "unknown",
        payment_id: p.payment_id,
        currency: p.currency || "USD"
      }
    };
  }
  return webhook;
}
```

### 跟踪订阅生命周期

```javascript track_subscriptions.js icon="js" expandable theme={null}
function handler(webhook) {
  const s = webhook.payload.data;
  switch (webhook.eventType) {
    case "subscription.active":
      webhook.url = "https://track.customer.io/api/v2/entity";
      webhook.payload = {
        type: "person",
        identifiers: {
          id: s.customer.customer_id
        },
        action: "subscription_started",
        name: "Subscription Started",
        attributes: {
          email: s.customer.email,
          subscription_id: s.subscription_id,
          product_id: s.product_id,
          amount: (s.recurring_pre_tax_amount / 100).toFixed(2),
          frequency: s.payment_frequency_interval,
          next_billing: s.next_billing_date
        }
      };
      break;
    case "subscription.cancelled":
      webhook.url = "https://track.customer.io/api/v2/entity";
      webhook.payload = {
        type: "person",
        identifiers: {
          id: s.customer.customer_id
        },
        action: "subscription_cancelled",
        name: "Subscription Cancelled",
        attributes: {
          email: s.customer.email,
          subscription_id: s.subscription_id,
          cancelled_at: s.cancelled_at,
          cancel_at_next_billing: s.cancel_at_next_billing_date
        }
      };
      break;
  }
  return webhook;
}
```

### 跟踪客户属性

```javascript track_attributes.js icon="js" expandable theme={null}
