Create a change order

 https://api.constructiononline.com/api/ChangeOrders?coInfo={coInfo}

This endpoint allows users to create a new change order for a project in their ConstructionOnline company account. If successful, the endpoint will return a record of the newly created change order. The new change order will be automatically assigned a unique numerical ID called 'ID', which will be used for any future references. The required fields for this endpoint include NAME, PRJ_ID, and CONDITION; all other properties are optional and can be entered during project creation or updated at a later time. Users must enter the properties for creation in the URL of the request.

Individual change order items cannot be added using this endpoint.
