# Publish current labels

`POST /v3/label-sets/{labelSetId}/versions`

Publishes an immutable snapshot of current entity, product, and vault-label
content. Geo policies remain live and are not included. When the canonical
content checksum matches the latest published version, the endpoint returns
that version with `publishOutcome: unchanged` and does not create a release.

## Path parameters

- `labelSetId` string, required

## Request body

- object
  - `versionKey` string
  - `aliases` string[]
  - `sourceRepo` string, nullable
  - `sourceRef` string, nullable
  - `sourceSha` string, nullable
  - `schemaAdapter` string

## Response `200`

Publishable label content is unchanged; the latest version is returned.
