  title: Microsoft Office Update a OneDrive File and Verify the Write
  summary: Read a file's metadata, back up its current bytes, upload new content, and read the item back.
  description: >-
    The read-modify-write round trip every OneDrive automation needs on
    Microsoft Graph. The workflow inspects the target driveItem to capture its
    size and last-modified stamp, downloads the current bytes so the caller
    holds a rollback copy, uploads replacement content, and reads the item back
    to prove the write landed and the modified timestamp advanced. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.

  summary: Safely replace the content of an existing OneDrive file and confirm the result.
  description: >-
    Captures the pre-update state of a driveItem, takes a content backup,
    replaces the content with the supplied bytes, and re-reads the item to
    verify the new size and lastModifiedDateTime.
  inputs:
    type: object
    required:
    - itemId
    - fileContent
    properties:
      itemId:
        type: string
        description: The id of the existing driveItem whose content is replaced.
      fileContent:
        type: string
        description: >-
          The replacement file content uploaded as an octet-stream body. This
          PUT replaces the item's content in full; it is not a partial patch.
  steps:
  - stepId: inspectBeforeUpdate
    description: >-
      Read the driveItem before writing so the caller records the pre-update
      size and lastModifiedDateTime to compare against after the upload.
    operationId: getMyDriveItem
    parameters:
    - name: item_id
      in: path
      value: $inputs.itemId
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      itemId: $response.body#/id
      itemName: $response.body#/name
      sizeBefore: $response.body#/size
      lastModifiedBefore: $response.body#/lastModifiedDateTime
  - stepId: backupContent
    description: >-
      Download the current bytes before they are overwritten so the caller can
      restore the previous version if the update is later rejected.
    operationId: downloadMyDriveItemContent
    parameters:
    - name: item_id

    - condition: $statusCode == 200 || $statusCode == 302
    outputs:
      backupStatus: $statusCode
  - stepId: uploadContent
    description: >-
      Replace the item's content with the supplied bytes. Graph returns the
      updated driveItem describing the newly written file.

  - stepId: verifyAfterUpdate
    description: >-
      Read the item back as an independent confirmation that the write is
      durable and that lastModifiedDateTime advanced past the pre-update stamp.
