Answer 1

When using this endpoint GET {urn}/metadata/{guid}/properties , you get all the properties of objects.

To get categories , you should use this endpoint GET {urn}/metadata/{guid} which gives you the hierarchy tree of all objects in the scene.

Revit files usually has this structure categories / families / types / instances , so if you parse the tree, you can easily get all objects for a given category .
