# Get Variant Attribute

Everything about one attribute of the Variant definition, the tenant's own or the platform's,
in every language: what it is, what its type carries, where a variant form draws it and what
may be changed about it — what a screen editing the attribute loads.
`attributeSetId` chooses the form the place is read from: that attribute set's Variant form
(left out, the default Variant form). It decides nothing else.
## 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`.
## Example

```http
GET /Metadata/Variants/attributes('frmt_strapcolour')?attributeSetId=7 HTTP/1.1
X-API-KEY: your-api-key-here
```
