Create a change order item

 https://api.constructiononline.com/api/ChangeOrderItems?coItemInfo={coItemInfo}

This endpoint allows users to create a new change order item for an existing change order in their ConstructionOnline company account. The change order item must be created for a specific change order within an existing project. If a change order ID is not included in the URL of the request, the change order item will fail to create.

The new change order item will be automatically assigned a unique numerical ID called ID, which will be used for any future references. Users should enter the properties for creation in the URL of the request—specifically, in the "coItemInfo" request parameter. The required properties for creation are NAME and CHANGE_ORDER_ID; all other properties are optional and can be entered during item creation or updated at a later time. If successful, the endpoint will return a record of the newly created change order item with the included properties.
