Trying to create a Devops Agent pool using REST api

I'm trying to create an agent pool (Azure devops Server) using powershell and invoke-restmethod. To do this I'm using the reference below to try a build up a correct json request body. https://docs.microsoft.com/en-us/rest/api/azure/devops/distributedtask/pools/add?view=azure-devops-rest-5.1 All basics in place (credentials etc - I have successfully run other tasks using other uris) Many attempts at finding the correct body, all pretty much with the same result, latest example below;

$requestBodyAgentPool = '{
    "Id": "3"
    "name": "Testpool",
    "isHosted": $false,
    "autoSize": $false,
    "poolType": "automation",
    "isLegacy": $false
}'

Using the following (verified the uri and credentials by running a GET)

$uriPool = "http://localhost/DefaultCollection/_apis/distributedtask/pools?api-version=5.1"

Invoke-RestMethod -Uri $uriPool -Method POST -ContentType 'application/json' -Body $requestBodyAgentPool -Credential $cred

Fails with below which to me means the parameter id is null.

Invoke-RestMethod : {"$id":"1","innerException":null,"message":"Value cannot be null.\r\nParameter name: pool.Name","typeName":"System.ArgumentNullException, mscorlib","typeKey":"ArgumentNullException","errorCode":0,"eventId":0}

I have a feeling this is just my inexperience with coding terms and reading the reference documentation but it is not clear to me if the format is wrong or I'm missing/wrong format a mandatory parameter (id or name?)

Suggest you could use some UI tool such as Postman to verify if you are able to run same Rest API. This will help you narrow down the issue. 

{
"name": "{poolname}",
"autoProvision": $true
}

The request body should be a json format. Try to explicitly add ConvertTo-Json for your post body.
