detectedApp resource relationship to managedDevices in Graph API

Question

Based on the detectedApp resource page for the Graph API, there is a relationship with the managedDevices resource.

When I try to use the expand parameter, the results for managedDevices are empty, selecting properties has no effect:

GET https://graph.microsoft.com/v1.0/deviceManagement/detectedApps?$expand=managedDevices

 {
            "id": "",
            "displayName": "Adobe Acrobat (64-bit)",
            "version": "22.003.20282",
            "sizeInByte": 0,
            "deviceCount": 17,
            "publisher": "",
            "platform": "windows",
            "managedDevices": []
        },

Is the expand Parameter not supported for this relationship?

Answer 1

@Chen, Byron, Thanks for posting in Q&A. Based on my checking, for the relationship with the managedDevices, I find we can use it to query one discovered app's managed device using the following method:

Action: Get

URL:https://graph.microsoft.com/beta/deviceManagement/detectedApps('<appid>')/managedDevices?$filter=&$top=20&$skip=0

Note: Change the appid with the one in your environment.

Hope the above information can help.

Answer 3

I have thousands of applications. I am trying to discover all the managed devices. Would it be better to iterate over all the application IDs, or is there a way to retrieve all managed devices and all detected applications using two API requests, one for devices and one for applications, to obtain all the fields with a common key between the two tables?
