  title: Microsoft Power Automate Cancel an In-Flight Run
  summary: Find a run that is still executing, confirm it is live, and cancel it.
  description: >-
    When a flow hangs on a stuck approval or a slow downstream call, an operator
    needs to stop that specific execution without deactivating the flow itself.
    This workflow lists the run history, branches on whether an execution is
    still Running or Waiting, re-reads that run to confirm it is genuinely live
    rather than acting on stale list data, and cancels it. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Cancel a flow run that is still in flight.
  description: >-
    Scans the run history for an execution in a Running or Waiting state,
    re-reads it to confirm it is still live, and cancels that single run while
    leaving the flow itself active.
  inputs:
    type: object
    required:
    - environmentName
    - flowName
    properties:
      environmentName:
        type: string
        description: The name of the environment holding the flow.
      flowName:
        type: string
        description: The name or ID of the flow whose run should be cancelled.
  steps:
  - stepId: listRuns
    description: >-
      List the flow's run history and branch on whether any execution is still
      in flight. A history of only terminal runs means there is nothing to cancel.
    operationId: listFlowRuns
    parameters:
    - name: environmentName

      value: $inputs.environmentName
    - name: flowName

  - stepId: confirmRunStillLive
    description: >-
      Re-read the candidate run immediately before cancelling. A long-running run
      can complete between the list and the cancel, and cancelling a finished run
      is a no-op worth avoiding.
