  title: Power BI Export a Report for Archive
  summary: Capture a report's metadata and page structure, then download the underlying PBIX file.
  description: >-
    The backup and source-control pattern for Power BI content. Exporting the
    PBIX on its own produces a binary with no context, so an archive that is
    actually restorable also needs the report's dataset binding and its page
    structure recorded alongside the file. This workflow reads the report
    metadata, enumerates its pages, and then downloads the PBIX. The export
    returns the file as a binary response body rather than JSON. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.

  summary: Archive a report as a PBIX file together with its metadata and pages.
  description: >-
    Reads a report's metadata and dataset binding, lists its pages, and exports
    the PBIX binary so the report can be archived or committed to source control.
  inputs:
    type: object
    required:
    - reportId
    properties:
      reportId:
        type: string
        description: The identifier of the report to export.
  steps:
  - stepId: inspectReport
    description: >-
      Read the report metadata, capturing the dataset binding and modification
      stamps that give the archived file its restore context.
    operationId: getReport
    parameters:
    - name: reportId
      in: path
      value: $inputs.reportId
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      reportName: $response.body#/name
      datasetId: $response.body#/datasetId
      reportType: $response.body#/reportType
      modifiedDateTime: $response.body#/modifiedDateTime
      modifiedBy: $response.body#/modifiedBy
  - stepId: listPages
    description: >-
      Enumerate the report's pages and their display order, recording the
      structure that the exported binary would otherwise leave opaque.
    operationId: getPages
    parameters:
    - name: reportId
      in: path
      value: $inputs.reportId
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      pages: $response.body#/value
      firstPageName: $response.body#/value/0/name
  - stepId: exportPbix
    description: >-
      Download the report as a PBIX file. The response body is the binary file
      itself rather than a JSON document.
