Create an estimate item

 https://api.constructiononline.com/api/EstimateItems?subcatID={subcatID}&itemInfo={itemInfo}

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

The new estimate 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 "itemInfo" request parameter. The only required property for creation is NAME; 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 estimate item with the included properties.
