APIC-EM REST (GET) call via PoweShell

Trying to execute an APIC-EM REST (GET) call via a PowerShell script.

The APIC-EM is self-certified hence need to use the first bulk of code lines ..

[System.Net.ServicePointManager]::CheckCertificateRevocationList = $false;

 Add-Type @"

    using System;

    using System.Net;

    using System.Net.Security;

    using System.Security.Cryptography.X509Certificates;

    public class ServerCertificateValidationCallback

    {

        public static void Ignore()

        {

            ServicePointManager.ServerCertificateValidationCallback +=

                delegate

                (

                    Object obj,

                    X509Certificate certificate,

                    X509Chain chain,

                    SslPolicyErrors errors

                )

                {

                    return true;

                };

        }

    }

"@

[ServerCertificateValidationCallback]::Ignore();

[System.Net.ServicePointManager]::CheckCertificateRevocationList = $false;

 ;

$Splat = @{

    Method      = 'GET'

    Uri         = 'https://10.122.6.150/api/v1/discovery/1'

    ContentType = "application/json"

    Headers     = @{authorization = "X-Auth-Token:ST-3166-nHrsi63Rbvkwze5aznoN-cas" }

}

 $response = Invoke-RestMethod @Splat

 After running the script (in PS admin window),  getting the following error:

 Invoke-RestMethod : { "response":{"errorCode":"RBAC","message":"Failed to provide a CAS service ticket to validate","detail":"Failed to provide a CAS service ticket to validate"}, "version":"1.0"} At C:\psScripts\rest2.ps1:38 char:13

+ $response = Invoke-RestMethod @Splat

+             ~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException

    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

The Token is working when running a query from through Postman (see screenshot)

the header is called "x-auth-token", not "authorisation".  Did you try:

 Headers     = @{X-Auth-Token = "ST-3166-nHrsi63Rbvkwze5aznoN-cas" }

 changed that to the following and it worked well (command: https://10.122.6.150/api/v1/discovery/count)

 changed the “Write-Host $response” to “Write-output $response” and I do see additional lines,

Refer the code here -https://github.com/darrenstarr/APICEMPowershell

it should be able to automate the entire process of claiming new devices, filling in template variables and deploying them.. Added a far more advanced templating system .
