Hello,
I am working on retrieve Dev NetApp Cluster information through ONTAP REST API with PowerShell.

But, when I initiate NetApp REST API though PowerShell in my laptop and got error like below.

PS C:\Users\TAC5665> $Cred = Get-Credential

cmdlet Get-Credential at command pipeline position 1

Supply values for the following parameters:

Credential

PS C:\Users\TAC5665> $Params = @{

>> Uri = https://nasoc03.d2-tdbfg.com/api/network/ethernet/ports

>> Authentication = "Basic"

>> Credential = $Cred

>> }

PS C:\Users\TAC5665>

PS C:\Users\TAC5665> Invoke-RestMethod @Params

Invoke-RestMethod : A parameter cannot be found that matches parameter name 'Authentication'.

You don't need Authentication - just Credential is sufficient (I believe they're actually mutually exclusive).

Example:

Invoke-RestMethod -Method Get -Uri 'https://{clusterip}/api/cluster' -Credential (Get-Credential)

Also, since you're using PSv5 and IF ONTAP is using a self-signed certificate you'll need to use the self-signed cert 'hack'.

If you don't already have this:

#Accept Self-Signed Certificates
Add-Type @"
    using System.Net;
    using System.Security.Cryptography.X509Certificates;
    public class TrustAllCertsPolicy : ICertificatePolicy {
        public bool CheckValidationResult(
            ServicePoint srvPoint, X509Certificate certificate,
            WebRequest request, int certificateProblem) {
            return true;
        }
    }
"@ -ea SilentlyContinue -wa SilentlyContinue 

[System.Net.ServicePointManager]::CertificatePolicy = [TrustAllCertsPolicy]::new()
