ADO - REST - Cannot find a way to get pipeline creator id

I need to know the person who created a pipeline in ADO

https://dev.azure.com/mycompany/myproject/_apis/pipelines/***?api-version=7.1

I get everything but a "createdby" field

{
    "_links": {
        "self": {
            "href": "https://dev.azure.com/****/****/_apis/pipelines/****?revision=**"
        },
        "web": {
            "href": "https://dev.azure.com/****/****/_build/definition?definitionId=****"
        }
    },
    "configuration": {
        "path": "azure-pipelines.yml",
        "repository": {
            "id": "*******************",
            "type": "***************"
        },
        "type": "yaml"
    },
    "url": "https://dev.azure.com/****/****/_apis/pipelines/****?revision=**",
    "id": ***,
    "revision": **,
    "name": "****",
    "folder": "\\****"
}

how can I achieve this ?

thanks for your help

Based on your description, you need to get the user who creates the Pipeline.

To meet your requirement, you can use the Rest API: Definitions - Get Definition Revisions

GET https://dev.azure.com/{organization}/{project}/_apis/build/definitions/{definitionId}/revisions?api-version=7.1

In the Response, you can check the response with revision value 1, where the changed user(changedBy) corresponds to the user who creates the pipeline.

For example:

 "value": [
    {
      "revision": 1,
      "name": "txx",
      "changedDate": "2024-10-15T14:41:59.987Z",
      "changeType": "add",
      "definitionUrl": "xx",
      "changedBy": {
        "displayName": "xxx",
        "url": "xx",
         .....
        "id": "dd61a310-16c1-6ca5-a217-f243df542c22",
        "uniqueName": "xx",
        "imageUrl": "xx",
        "descriptor": "msa.ZGQ2MWEzMTAtMTZjMS03Y2E1LWEyMTctZjI0M2RmNTQyYzIy"
      }
    },
   ]

PowerShell sample:

$token = "PAT"

$BuildDefinitionID = PipelineID

$OrgName= "OrganizationName"

$ProjName= "ProjectName"

$GetBuilddefinitionurl="https://dev.azure.com/$($OrgName)/$($ProjName)/_apis/build/definitions/$($BuildDefinitionID)/revisions?api-version=7.1"

$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($token)"))

$GetBuildRevisions= Invoke-RestMethod -Uri $GetBuilddefinitionurl -Headers @{Authorization = "Basic $token"} -Method Get  -ContentType application/json


foreach($revision in $GetBuildRevisions.value)
{

   if($revision.revision -eq "1")
   {
      $PipelineCreatorID = $revision.changedBy.id

      $PipelineCreatorName= $revision.changedBy.uniqueName

      echo "Creator ID: $PipelineCreatorID ; Creator Name: $PipelineCreatorName"
   }

}
