Response

Returns an object with number, label, revision, created_by, client and created_at. This is a real response, shortened to two items per list.

{
  "number": 3,
  "label": "Before launch",
  "revision": 7,
  "created_by": null,
  "client": {
    "name": "docs-examples",
    "interface": "rest"
  },
  "created_at": "2026-10-07T20:14:41.903Z"
