Adding a node to a container using rest api

Hi Thwack,

I need to add a node to a container.  The examples from both solarwinds and some other blogs reflect using XML.  Is it possible to form it into a rest call, using powershell?

forexample

$nodeSetting =

  @{

    containerId=$containerId

    MemberDefinitionInfo=???;

  }

  $nodeSettingjson = ConvertTo-Json $nodeSetting

  $url = "https://$($hostname):17778/SolarWinds/InformationService/v3/Json/Invoke/Orion.Container/AddDefinition"

  $result = Invoke-RestMethod -Uri $url -Credential $solarcreds -Method Post -Body $nodeSettingjson -ContentType application/json

Thanks
