Update Attribute
PUT/api/attributes/:id
Updates an existing attribute. All fields are optional (PATCH semantics). Providing option_values syncs them — values not included will be deleted.
products:writeGrant this scope to your token under Settings → Developer → Personal Access Tokens.
Authentication: Requires Bearer token.
Each entry in option_values may carry an optional variant SWATCH — swatch_hex (a hex colour, max 20) and/or swatch_image_url (an image URL, max 500). When the attribute is used as a variant axis (e.g. Color), channels that support swatches (Walmart) render this chip for every variant that selects the value. Send null to clear a swatch.
Returns 422 with code IsLinked if the update would remove an option value that is still assigned to a product — the response lists the in-use values under errors[].data.in_use. Add those values back, or reassign/clear them on the affected products, before removing the option.

Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.
Unprocessable Entity
