Returns all selection subcategories for the project that corresponds with the provided ID
https://api.constructiononline.com/SelectionSubCategories?projectID={projectID}
This endpoint allows users to extract all selection subcategories from a project within their ConstructionOnline company account. Users must know the unique ID assigned to the project to call this endpoint. This endpoint does not return individual selection choices belonging to each subcategory. Please note that the ConstructionOnline API refers to selections (middle tier level of organization for client selections) as selection subcategories, as mentioned below.
NOTE:
In ConstructionOnline, client selections are organized into three different tiers: Category > Selection > Choice
Category is the broadest level of organization, Selection is the secondary level of organization, and Choice is the most granular level of organization. Users approve selections at the Choice level.
However, the ConstructionOnline API refers to the different levels of client selections using the following terms: Category > Subcategory > Choice
👉 In other words, a selection is referred to as a selection subcategory object in the API.
