In my last blog post I shared about ‘Scripted REST API’ getDisplayValue() tip. Now, here lets see Out of the Box option. When we query the CI with a query “sysparm_query=name=$($ConfigurationItem)&sysparm_limit=1”

param ( $ConfigurationItem = 'Car-3' ) try { $Uri = "https://dev42835.service-now.com/api/now/table/cmdb_ci?sysparm_query=name=$($ConfigurationItem)&sysparm_limit=1" $admin = "admin" $password = "admin" | ConvertTo-SecureString -AsPlainText -Force $Credential = New-Object pscredential -ArgumentList ($admin , $password) $Result = Invoke-RestMethod -Uri $Uri -Method Get -Credential $Credential [pscustomobject]@{ Name = $Result.result.name ManagedBy = $Result.result.managed_by.value Vendor = $Result.result.vendor.value } } catch { $_.Exception } |
We get the output illustrated below.
Now, add sysparm_display_value=true in the URL and see the results as actual values instead of ID

$Uri = "https://dev42835.service-now.com/api/now/table/cmdb_ci?sysparm_query=name=$($ConfigurationItem)&sysparm_limit=1&sysparm_display_value=true" $admin = "admin" $password = "admin" | ConvertTo-SecureString -AsPlainText -Force $Credential = New-Object pscredential -ArgumentList ($admin , $password) $Result = Invoke-RestMethod -Uri $Uri -Method Get -Credential $Credential [pscustomobject]@{ Name = $Result.result.name ManagedBy = $Result.result.managed_by.display_value Vendor = $Result.result.vendor.display_value } |
After adding the sysparm_display_value=true we see the display_value property! This helps to get readable output. (sysparm_query=name=$($ConfigurationItem)&sysparm_limit=1&sysparm_display_value=true)
Enjoy servicenow and PowerShell!
