Powershell api issue not able to reach to tenant URL

[hranjan3 (Himanshu Ranjan)]

Hi, Can someone please suggest me solution for one issue I am facing while trying to use Sailpoint API from Powershell. Here is the detailed info about issue:

This is one simple script I have:

$Parameters = @{
    "Filters" = 'name co "Test User"'
}

# Accounts List
try {

    Invoke-Paginate -Function "Get-Accounts" -Increment 250 -Limit 1000 -InitialOffset 0 -Parameters $Parameters

} catch {
    Write-Host ("Exception occurred when calling Invoke-Paginate: {0}" -f $_.ErrorDetails)
    Write-Host ("Response headers: {0}" -f $_.Exception.Response.Headers)
}

I am executing it from Powershell version 7 but its giving error message:

PS C:\Users\Documents\Sailpoint powershell works\SPAPITest> .\Test-api-2.ps1
Conversion from JSON failed with error: Unexpected character encountered while parsing value: A. Path '', line 0, position 0.

Trial with other script: I have one more script:

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Accept", "application/json")
$headers.Add("Authorization", "Bearer <token>")

$certData = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2(, [Convert]::FromBase64String($cert))


$response = Invoke-RestMethod 'https://tenant.api.identitynow.com/v3/certifications' -Method 'GET' -Headers $headers
$response | ConvertTo-Json

while running this script I get error message:

PS C:\Users\Documents\Sailpoint powershell works\SPAPITest> .\test2.ps1
Invoke-RestMethod: C:\Users\Documents\Sailpoint powershell works\SPAPITest\test2.ps1:8
Line |
   8 |  $response = Invoke-RestMethod 'https://tenant.api.identitynow.com/v3/ …
     |              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | A connection attempt failed because the connected party did not properly respond after a period of time, or
     | established connection failed because connected host has failed to respond.

Trial case 3: for the same script I did little modification and tried to run from Powershell version 5.2:

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Accept", "application/json")
$headers.Add("Authorization", "Bearer <token>")

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;
        }
    }
"@
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy


$response = Invoke-RestMethod 'https://tenant.api.identitynow.com/v3/certifications' -Method 'GET' -Headers $headers
$response | ConvertTo-Json

It works fine.

But when I modify above script for powershell 7 version like:

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Accept", "application/json")
$headers.Add("Authorization", "Bearer <token>")

$certData = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2(, [Convert]::FromBase64String($cert))


$response = Invoke-RestMethod 'https://tenant.api.identitynow.com/v3/certifications' -Method 'GET' -Headers $headers
$response | ConvertTo-Json

it gives error message:

Invoke-RestMethod: C:\Users\Documents\Sailpoint powershell works\SPAPITest\test2.ps1:8
Line |
   8 |  $response = Invoke-RestMethod 'https://tenant.api.identitynow.com/v3/ …
     |              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | A connection attempt failed because the connected party did not properly respond after a period of time, or
     | established connection failed because connected host has failed to respond.
null

Could you please suggest if anything I am missing or changes I need to make to fix this issue.

Try to force it to use TLS by adding the following line before you make any calls:

[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12

thanks Kevin, I tried adding the suggested line but error remains same.

I forgot to add info - all my scripts are running fine in my local system without adding any info for certificate or TLS… but when I try to run same script from one other windows server which I access using RDP, its not working.

Hi Kevin,
Can you try the below. Create a variable and add the url in the same and then use it in the Invoke-Method. I am suspecting there many be issues related to encoding of the URL.

$Uri = ‘https://tenant.api.identitynow.com’
Invoke-RestMethod $Uri

I’d suggest using VSCODE and the debugger to step through the code and investigate the specifics.

Also verify that the version of powershell on the other host is the same as the host you have it working.
