# Interact with the Order Lifecycle

#### Overview

Changing the status of an order is an important part of tillit as it controls the execution of activities. To correctly trigger these activity, the correct endpoint need to be utilised. It is not advised that you change the status of an order via the `PUT:/core/order-instance` endpoint Instead the `POST:/core/order-manager` endpoint needs to be used.
