Example: Append to Existing Notes

Notes are replaced, not appended. To preserve existing notes: 
async function appendNote(subscriptionId, newNote) {
  const subscription = await getSubscription(subscriptionId);
  const timestamp = new Date().toISOString().split('T')[0];

  const updatedNotes = subscription.notes
    ? `${subscription.notes}\n\n[${timestamp}] ${newNote}`
    : `[${timestamp}] ${newNote}`;

  return await updateSubscriptionNotes(subscriptionId, {
    notes: updatedNotes
  });
}

​
Example: Log Support Interaction

async function logSupportInteraction(subscriptionId, ticketId, summary) {
  const subscription = await getSubscription(subscriptionId);
  const entry = `Support ticket #${ticketId}: ${summary}`;

  const notes = subscription.notes
    ? `${subscription.notes}\n${entry}`
    : entry;

  await updateSubscriptionNotes(subscriptionId, { notes });
}

​
Example: Bulk Update Notes

async function addNoteToActiveSubscriptions(customerId, note) {
  const { subscriptions } = await listSubscriptions({
    customerId,
    status: 'active'
  });

  for (const sub of subscriptions) {
    const updatedNotes = sub.notes
      ? `${sub.notes}\n${note}`
      : note;

    await updateSubscriptionNotes(sub.subscriptionId, {
      notes: updatedNotes
    });
  }

  return { updated: subscriptions.length };
}

​
Notes Best Practices

  • Be concise but include relevant details
  • Use timestamps when logging events
  • Include references (ticket IDs, order numbers)
  • Avoid sensitive data (use separate secure storage for PII)
