PowerShell – How do I iterate a PSCustomObject nested object?

I feel like this is something simple and I’m just not getting it, and I’m not sure if my explanation is great.
I have this below JSON file, and I want to get "each App" (App1, App2, App3) under the "New" object

In this script line below I’m essentially trying to replace "TestApp2" with some variable. I guess I’m trying to get TestApp2 as an object without knowing the name.
And I realize that the foreach loop doesn’t do anything right now

Write-Host $object.Value.TestApp2.reply_urls

JSON:

{
  "New": {
    "App1": {
      "reply_urls": [
        "https://testapp1url1"
      ]
    },
    "App2": {
      "reply_urls": [
        "https://testapp2url1",
        "https://testapp2url2"
      ]
    },
    "App3": {
      "reply_urls": [
        "https://testapp3url1",
        "https://testapp3url2",
        "https://testapp3url3"
      ]
    }
  },
  "Remove": {
      "object_id": [
        ""
      ]
  }
}

Script:

$inputFile = Get-Content -Path $inputFilePath -Raw | ConvertFrom-Json
foreach ($object in $inputFile.PsObject.Properties)
{
    switch ($object.Name)
    {
        New
        {
            foreach ($app in $object.Value)
            {
               Write-Host $object.Value.TestApp2.reply_urls
               # essentially want to replace this line with something like
               # Write-Host $app.reply_urls
            }
        }

        Remove
        {
        }
    }
}

Output:

https://testapp2url1 https://testapp2url2

>Solution :

You can access the object’s PSObject.Properties to get the property Names and property Values, which you can use to iterate over.

For example:

foreach($obj in $json.New.PSObject.Properties) {
    $out = [ordered]@{ App = $obj.Name }
    foreach($url in $obj.Value.PSObject.Properties) {
        $out[$url.Name] = $url.Value
    }
    [pscustomobject] $out
}

Produces the following output:

App  reply_urls
---  ----------
App1 {https://testapp1url1}
App2 {https://testapp2url1, https://testapp2url2}
App3 {https://testapp3url1, https://testapp3url2, https://testapp3url3}

If you just want to output the URL you can skip the construction of the PSCustomObject:

foreach($obj in $json.New.PSObject.Properties) {
    foreach($url in $obj.Value.PSObject.Properties) {
        $url.Value
    }
}
