Cancel all running flow runs for a flow in an environment

I am repeating a sample found within the CLI for Microsoft 365 examples which was insanely helpful for me.

I created a bulk update of about 2000 items within a SharePoint list – each one triggered a flow and with 2000 flows running at the same time, they started to time out, fail and just not complete – I needed to cancel all of them and start again

I found the code block on the M365 CLI site as i listed above.
You need the following

Install the M365 CLI in windows

npm i -g @pnp/cli-microsoft365

Log into m365 through a browser using

m365 login

Then run the following

$flowEnvironment = 'YourEnvironmentId'
$flowGUID = 'TheFlowGUID'
$flowRuns = m365 flow run list --environment $flowEnvironment --flow $flowGUID --output json | ConvertFrom-Json
foreach ($run in $flowRuns) {
  if ($run.status -eq "Running") {
    Write-Output "Run details: " $run
    # Cancel all the running flow runs
    m365 flow run cancel --environment $flowEnvironment --flow $flowGUID --name $run.name --confirm
    Write-Output "Run Cancelled successfully"
  }
}

The Environment and flow GUID can be found within the URL of your flow

Within the flow manage, open your flow – the references we are looking for are in the URL

https://us.flow.microsoft.com/manage/environments/Default-8a47f942-xxxx-yyyy-a2c7-ced012b09a0a/flows/f0d07662-9ab2-bbbb-aaaa-dd11f2f47a47/details

The environment = ‘Default-8a47f942-xxxx-yyyy-a2c7-ced012b09a0a’

The flow GUID = ‘f0d07662-9ab2-bbbb-aaaa-dd11f2f47a47’
