Azure DevOps set permissions via Rest Api Access Control List

Question

I'm trying to set permissions using ACL with project permission namespace. In the request bodyInfo, I am passing '16' for allow so that I will allow Administer Build (16) permission for the group but nothing happens.

$securityNamespaceId = "52d39943-cb85-4d7f-8fa8-c6baac873819"
$groupDesc = "Microsoft.TeamFoundation.Identity;S-1-9-1551374245-3474010476-3658975049-2966243200-2961816057-1-3769221364-1224424009-2749800435-4143997070"
$projectId = "12313142-eec0-4c3d-b9b5-44d0c3973b3e"
$token = "`$PROJECT:vstfs:///Classification/TeamProject/$($projectId)"
$allowMask = 16
$denyMask = 0

$bodyInfo = @" 
   { 
      "token": "$Token", 
      "merge": false, 
      "accessControlEntries": [ 
         { 
            "descriptor": "$groupDesc", 
            "allow": $AllowMask, 
            "deny": $DenyMask, 
            "extendedinfo": {} 
         } 
      ] 
   } 
"@

$uri = "https://dev.azure.com/{organization}/_apis/accesscontrolentries/52d39943-cb85-4d7f-8fa8-c6baac873819?api-version=5.0"

$result = (Invoke-RestMethod -Method Post -Uri $uri -Body $bodyInfo -Headers $headers -ContentType "application/json")

Answer 1

In your script,you want to use project-level token to modify Administer Build permission in build security. I tested it on postman and found that using project-level token to modify the build security permission, the response status was 200, but in the UI, the permissions were not actually changed.You can try to use build-level token to make changes to build security permission.

Hope this helps.
