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

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()

Thanks a lot for advise. Di do not know detail about our Env using which certificate, but I tried above command from our PowerShell v.5.1 env and got error like below

PS C:\Users\TAC5665> Invoke-RestMethod -Uri "https://nasoc03.d2-tdbfg.com/api/cluster" -Credential (Get-Credential)

cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential
Invoke-RestMethod : The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
At line:1 char:1
+ Invoke-RestMethod -Uri "https://nasoc03.d2-tdbfg.com/api/cluster" -Cr ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

 

What I research before The parameter authentication is only available within powershell 6.0+.

https://github.com/dnewsholme/GoogleDynamicDNS/issues/1

Is that true?

Plz advise on that.
