Transformation Code Examples

​
Basic Event Payload

basic_event.js
function handler(webhook) {
  if (webhook.eventType === "payment.succeeded") {
    const p = webhook.payload.data;
    webhook.payload = {
      name: "payment.succeeded",
      data: {
        payment_id: p.payment_id,
        amount: (p.total_amount / 100).toFixed(2),
        currency: p.currency || "USD",
        customer_email: p.customer.email,
        customer_name: p.customer.name,
        payment_method: p.payment_method || "unknown"
      },
      user: {
        email: p.customer.email
      },
      ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
    };
  }
  return webhook;
}

​
Subscription Event Handler

subscription_event.js
function handler(webhook) {
  const s = webhook.payload.data;
  switch (webhook.eventType) {
    case "subscription.active":
      webhook.payload = {
        name: "subscription.started",
        data: {
          subscription_id: s.subscription_id,
          customer_email: s.customer.email,
          customer_name: s.customer.name,
          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
        },
        user: {
          email: s.customer.email
        },
        ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
      };
      break;
    case "subscription.cancelled":
      webhook.payload = {
        name: "subscription.cancelled",
        data: {
          subscription_id: s.subscription_id,
          customer_email: s.customer.email,
          cancelled_at: s.cancelled_at,
          cancel_at_next_billing: s.cancel_at_next_billing_date
        },
        user: {
          email: s.customer.email
        },
        ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
      };
      break;
  }
  return webhook;
}

​
Dispute Event Handler

dispute_event.js
function handler(webhook) {
  if (webhook.eventType.startsWith("dispute.")) {
    const d = webhook.payload.data;
    webhook.payload = {
      name: webhook.eventType,
      data: {
        dispute_id: d.dispute_id,
        payment_id: d.payment_id,
        amount: (d.amount / 100).toFixed(2),
        status: d.dispute_status,
        stage: d.dispute_stage,
        remarks: d.remarks || "",
        urgent: webhook.eventType === "dispute.opened"
      },
      user: {
        email: d.customer?.email || "unknown"
      },
      ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
    };
  }
  return webhook;
}
