FreshAgent Get Asset Data - powershell

Question

I am trying to fetch asset data from the Fresh client with Powershell. I am able to get any asset by typing it's name but I want to save some of the variables it returns so I can use it further.
$naam = Read-Host "Voer product naam in"
# Set global variables
$APIKey = 'Myapikey'
$EncodedCredentials = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $APIKey,$null)))
$HTTPHeaders = #{ "X-ApiKey" = $APIKey}
$HTTPHeaders.Add('Authorization', ("Basic {0}" -f $EncodedCredentials))
$HTTPHeaders.Add('Content-Type', 'application/json')
$URL = 'https://helpdesk.company.nl/cmdb/items/list.json?field=name&q='+$naam
(Invoke-WebRequest -Method Get -Uri $URL -Headers $HTTPHeaders ).content
The following are some of the values that return after I run the above
{"config_items":[{"id":25000477949,"name":"SYS-MB1334","description":null,"ci_type_id":25000015988,"impact":1,"created_at":"2020-03-12T10:14:40+01:00","updated_at":"2020-04-24T16:42:42+02:00"
I would like to save the name and id variable for example

Answer 1

Unfortunately, the JSON you show is invalid.
Suppose the json returned from
$output = (Invoke-WebRequest -Method Get -Uri $URL -Headers $HTTPHeaders ).Content
looks like:
{"config_items":
[{"id":25000477949,"name":"SYS-MB1334","description":null,"ci_type_id":25000015988,"impact":1,"created_at":"2020-03-12T10:14:40+01:00","updated_at":"2020-04-24T16:42:42+02:00"},
{"id":12345678901,"name":"SYS-MB9876","description":null,"ci_type_id":12358745896,"impact":1,"created_at":"2020-03-12T10:14:40+01:00","updated_at":"2020-04-24T16:42:42+02:00"}]
}
Then you can collect the properties you need from the config_items using:
$result = ($output | ConvertFrom-Json).config_items |
Select-Object #{Name = 'Id'; Expression = {$_.id}},
#{Name = 'Name'; Expression = {$_.name}}
# output on screen
$result
# output to CSV file
$result | Export-Csv -Path 'X:\TheOutput.csv' -NoTypeInformation
Output on screen would look like
Id Name
-- ----
25000477949 SYS-MB1334
12345678901 SYS-MB9876
Hope that helps
