  title: Autodesk Add a New Version to an Existing File
  summary: Search a folder for a file, read its current tip, create a new version, and list the version history.
  description: >-
    Autodesk Docs and BIM 360 never overwrite a file; they version it. This is the
    flow a desktop sync agent or a CI pipeline runs when it has new bytes for a file
    that already exists: search the folder for the file by display name, read its
    current tip version, create a new version pointing at freshly uploaded storage,
    and list the version history to confirm the new tip. Every step spells out its
    request inline so the flow can be read and executed without opening the underlying
    OpenAPI description.

  summary: Version an existing project file rather than replacing it.
  description: >-
    Searches a folder hierarchy for the item by display name, reads the item to
    capture its current tip, creates a new version bound to a storage object, and
    lists versions to confirm the history.
  inputs:
    type: object
    required:
    - projectId
    - folderId
    - fileName
    - storageObjectId
    properties:
      projectId:
        type: string
        description: The project containing the file.
      folderId:
        type: string
        description: The folder to search beneath for the existing file.
      fileName:
        type: string
        description: Display name of the file to version (e.g. "tower.rvt").
      fileType:
        type: string
        description: File extension to narrow the search (e.g. "rvt").
      storageObjectId:
        type: string
        description: >-
          The storage object URN holding the new bytes for this version.
      versionExtensionType:
        type: string
        description: >-
          The version extension type for the host product (e.g.
          "versions:autodesk.bim360:File").
        default: versions:autodesk.bim360:File
  steps:
  - stepId: findExistingFile
    description: >-
      Search the folder hierarchy for the file by display name. Search walks
      subfolders, unlike a plain folder contents listing, and requires the data:search
      scope.
    operationId: searchFolder
    parameters:
    - name: project_id
      in: path
      value: $inputs.projectId

      value: $inputs.folderId
    - name: filter[displayName]
      in: query
      value: $inputs.fileName
    - name: filter[fileType]
      in: query
      value: $inputs.fileType

    - condition: $statusCode == 200
    - context: $response.body

      type: jsonpath
    outputs:
      itemId: $response.body#/data/0/id
      matches: $response.body#/data
  - stepId: readCurrentTip
    description: >-
      Read the item to capture the version that is currently the tip, so the caller
      can tell what it is superseding.
    operationId: getItem
    parameters:
    - name: project_id
      in: path

      reserved: $response.body#/data/attributes/reserved
  - stepId: createNewVersion
    description: >-
      Create the new version, relating it to the existing item and to the storage
      object holding the new bytes. This becomes the item's tip.
    operationId: createVersion
