Parsing JSON array with PowerShell - json

Question

I'm having issues returning specific data from an API query with PowerShell. I'm making a simple API call to grab a user which works great.
$Response = Invoke-RestMethod -uri $uri -Method GET -Headers $Headers
$Response
The call returns the following.
Total Sum Users Groups
----- ----- ----- ------
1 1 #{123456789=} #{Test Users=System.Object[]; Global Users=System.Object[]...
$Response.Users returns the following
123456789
---------
#{name= Test Case; fullname=Test Tester Case; office=Area 51;....
The issue is the number "123456789" is a unique identifier that changes with every user. In order to pull the needed data from each user I need to be able to parse and grab just that number.
Here is the JSON output from $Response.Users
{
"123456789": {
"name": "Test Case",
"fullname": "Tester Test Case",
"office": "Area 51",
"country": "United States",
"groups": [
"Test Users",
"Global Users",
"Test OU"
]
}
}
Any help is greatly appreciated!
Thanks

You can access the name of the note property using the default powershell property PsObject and retrieve the name of it:
$json =
#'
{
"123456789": {
"name": "Test Case",
"fullname": "Tester Test Case",
"office": "Area 51",
"country": "United States",
"groups": [
"Test Users",
"Global Users",
"Test OU"
]
}
}
'#
$json | ConvertFrom-Json | ForEach-Object {$_.PsObject.Properties.Name}
Or in your case:
$Response.Users | ConvertFrom-Json | ForEach-Object {$_.PsObject.Properties.Name}
Should do the trick ;-)
