# listContactTasks

List every to-do task on one contact (by contactId from findContacts/getContact/listMyTasks): title, description, dueDate, completedAt, and assigned participants. Use it to review a contact's outstanding work before a call, or to find the taskId + contactId pair completeTask needs. Appointments are separate: see listAppointments.
