# Get Category Attribute

Everything about one attribute of the Category definition, the tenant's own or the
platform's, in every language: what it is, what its type carries, where the category form
draws it and what may be changed about it — what a screen editing the attribute loads.
## Response
**200 OK** — the attribute under `value`, in the members a create reports it in: what every
attribute has, and what its type carries in every language — a checklist's `options` with
their `translations`, a table's `templates` and `hasStartingTable`, an image's `sizeVariants`
and `fileNameAttributes`, the `linkingPattern` of an image or a file, a related items
attribute's target and `separator`. Then where the form draws it, `placement` (`null` when
the form does not lay it out), and what may be changed about it, `editability`.

GET /Metadata/Categories/attributes('cat_boxmaterial') HTTP/1.1
