Reached out to support and they said they didnt have a way to bulk remove duplicate devices . 

They have this link but its a little lacking. 

https://developer.automox.com/openapi/axconsole/operation/deleteDevice/

With Chat GPT and a little trouble shooting, i came up with this powershell script that worked for me. 

you will need to do an export of all devices, find the duplicates and get a list of device id’s and put them in column A with deviceid as the header, save as *.csv. 

Enjoy!

#Add api key and orgid!

$apiKey = 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'
$orgId = xxxxxx
$headers = @{ 
      "Authorization" = "Bearer $apiKey"
      "Content-Type"  = "application/json"
      
}

#Edit csv path and log path!

# Paths
$csvPath = "C:\Path\*.csv"
$logPath = "C:\Path\*.txt"

# Clear previous log
if (Test-Path $logPath) {
    Remove-Item $logPath
}
New-Item -Path $logPath -ItemType File -Force | Out-Null

# Read device IDs
$deviceIds = Import-Csv -Path $csvPath

foreach ($row in $deviceIds) {
    $deviceId = $row.DeviceId

    if (-not vstring]::IsNullOrWhiteSpace($deviceId)) {
        $url = "https://console.automox.com/api/servers/" + $deviceId + "?o=$orgId"
        write-output $url
        try {
            $response = (Invoke-WebRequest -Method Delete -Uri $url -Headers $headers).Content
            $successMsg = "$(Get-Date -Format 'yyyy-MM-dd HHss') - Deleted device ID ${deviceId}: $($response.StatusCode) $($response.StatusDescription)"
            Write-Host $successMsg
            Add-Content -Path $logPath -Value $successMsg
        }
        catch {
            $errorMsg = "$(Get-Date -Format 'yyyy-MM-dd HHss') - Failed to delete device ID ${deviceId}: $($_.Exception.Message)"
            Write-Host $errorMsg
            Add-Content -Path $logPath -Value $errorMsg
        }
    }
    else {
        $skipMsg = "$(Get-Date -Format 'yyyy-MM-dd HHss') - Skipped empty or invalid DeviceId row."
        Write-Host $skipMsg
        Add-Content -Path $logPath -Value $skipMsg
    }
