HI

I apologize in advance if that question was asked but I cannot find answers :( 

I need to retrieve following information through API: 

1. retrieve members through API from static computer groups - i need to list computer names that belong to specific computer groups.  All i'm able to find is how to list computer groups, but not how to retrieve members. 

# Endpoint to retrieve computer groups
$computerGroupsUrl = "$jamfUrl/api/v1/computer-groups"

# Request computer groups
$responseComputerGroups = Invoke-RestMethod -Uri $computerGroupsUrl -Method Get -Headers $headers -ErrorAction Stop

 

2. retrieve members through API from smart computer groups - i need to list computer names that belong to specific computer groups

 

3. retrieve data through API from "reports" found under "Search inventory" 

Do you already know the static groups you need the members of? Or do you need to read ALL computer groups, determine which ones are static, then output the members of all of them? Or do you have like 8 static groups and you just want an API script that will list the members?

If its just 1 group then you can do the following. You will need to install JQ (https://jqlang.github.io/jq/download/) as I use this to easily manipulate JSON datasets I get back from the API


If you use this in Jamf, you need to set up an API client &  roles then add the following script parameters:


4: Jamf URL
5: Client ID
6: Client Secret
7: Device group ID


If you want to enter more than one group then adapt how it reads parameter 7 and add it to an array instead a variable then loop through it to get each group and assign the results to a new array.
