Below PowerShell script helped me to pull the list using PAT.

function GetUrl() { param( [string]$orgUrl, [hashtable]$header, [string]$AreaId )

# Area ids

# Build the URL for calling the org-level Resource Areas REST API for the RM APIs
$orgResourceAreasUrl = [string]::Format("{0}/_apis/resourceAreas/{1}?api-preview=5.0-preview.1", $orgUrl, $AreaId)

# Do a GET on this URL (this returns an object with a "locationUrl" field)
$results = Invoke-RestMethod -Uri $orgResourceAreasUrl -Headers $header

# The "locationUrl" field reflects the correct base URL for RM REST API calls
if ("null" -eq $results) {
    $areaUrl = $orgUrl
}
else {
    $areaUrl = $results.locationUrl
}

return $areaUrl

}

$orgUrl = "https://dev.azure.com/myorg" $personalToken = "mytoken"

Write-Host "Initialize authentication context" -ForegroundColor Yellow $token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($personalToken)")) $header = @{authorization = "Basic $token"}
