# Zapier Trigger: Change Order Status Change

> Zapier trigger that fires when a change order's status changes in Portal.io.

This endpoint is used by the Portal.io Zapier integration. It fires when a change order's status changes in your Portal.io account. A change order is a child proposal linked to a parent proposal.

The payload is identical to the [Proposal Status Change](/api-reference/zapier-triggers/proposal-status-change) trigger. The system automatically routes the event as a change order trigger when the proposal has a parent.
