  title: Grafana Roll a Dashboard Back to a Previous Version
  summary: Inspect a dashboard's version history, review a target version, and restore it.
  description: >-
    Someone broke a dashboard and you need the last good one back. This workflow
    reads the current dashboard, lists its version history, pulls the full model
    of the target version so the change can be reviewed before it is applied,
    and then restores it. The review step matters: restoring is itself a new
    version, so looking before you leap is cheaper than rolling back a rollback.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.

    required:
    - dashboardUid
    - targetVersion
    properties:
      dashboardUid:
        type: string
        description: UID of the dashboard to roll back.
      targetVersion:
        type: integer

  steps:
  - stepId: readCurrentDashboard
    description: >-
      Read the dashboard as it stands today, capturing the current version so
      the rollback can be described and, if needed, reversed.
    operationId: getDashboardByUID
    parameters:
    - name: uid
      in: path
      value: $inputs.dashboardUid
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      currentDashboard: $response.body#/dashboard
      currentVersion: $response.body#/dashboard/version
      meta: $response.body#/meta
  - stepId: listVersions
    description: >-
      List the dashboard's version history, newest first, so the target version
      can be confirmed to exist and its commit message read.
    operationId: getDashboardVersionsByUID
    parameters:
    - name: uid
      in: path
      value: $inputs.dashboardUid
    - name: limit
      in: query
      value: $inputs.limit

      versions: $response.body#/versions
      latestVersion: $response.body#/versions/0/version
  - stepId: reviewTargetVersion
    description: >-
      Fetch the full stored model of the target version. Read this before
      restoring so you know exactly what is about to become current.
    operationId: getDashboardVersionByUID
    parameters:
    - name: uid
      in: path
      value: $inputs.dashboardUid
    - name: DashboardVersionID

  - stepId: restoreVersion
    description: >-
      Restore the reviewed version. Grafana applies it as a new version on top of
      the history rather than deleting anything, so the broken version remains in
      the record.
