How to list vCenter (VCSA) services in powershell / Powercli

I need to list the Linux-based vCenter (VCSA) Services in powercli / powershell script. I don't know of any powercli cmdlet that will list the services. I thought of using vSphere REST API newly introduced in vSphere 6.5

The two calls I tried using postman / vSphere API explorer failed with unable to authorize:

https://{server}/rest/vcenter/services

https://{server}/rest/appliance/services

I was able to use [email protected] to list vms and create new vms, so I am not sure what's going on

Tested listing services using vSphere REST API in postman and REST explorer

 $url = "https://{server}/rest/vcenter/services"
Invoke-RestMethod -Method 'Get' -Uri $url -Credential $Cred

My questions: 1) Is there a powercli command to list services in linux based vCenter (VCSA) 2) Any idea how to have this done using vSphere REST API

Solution

The below worked. Please use an SSO account when prompted for credentials and confirm the account use has privilege to view the services from vSphere client.

Check: https://communities.vmware.com/thread/618154

$vcenter = <vcsa-FQDN>
$BaseUri = "https://$vcenter/rest/"

$SessionUri = $BaseUri + "com/vmware/cis/session"

$Cred = Get-Credential

$auth = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($Cred.UserName + ':' + $Cred.GetNetworkCredential().Password))

$header = @{

    'Authorization' = "Basic $auth"

}

$authResponse = (Invoke-RestMethod -Method Post -Headers $header -Uri $SessionUri).Value

$sessionHeader = @{"vmware-api-session-id" = $authResponse }

$result = Invoke-Restmethod -Method Get -Headers $sessionHeader -Uri ($BaseUri + "vcenter/services")

$result.value.value | select Name_Key, Health, State, Description_Key
