I am trying to get all the applications installed on all the devices ios,ipad,iphone,android and windows devices using microsoft graph API.
my approach was first to get all the devices using https://graph.microsoft.com/v1.0/deviceManagement/manageddevices and then passing each device id to https://graph.microsoft.com/v1.0/deviceManagement/manageddevices('device_id')?$expand=detectedApps
but there are huge number of devices so the number of API calls i have to make is too many.
Is there any alternate way to do it .
Note:i tried https://graph.microsoft.com/v1.0/deviceManagement/manageddevices?$expand=detectedApps here but this seems to be not working.
Thanks
managedDevice resource type doesn't have any relationship to detectedApp but detectedApp resource type has a relationship to managedDevice.
Make a first call to get all devices
GET https://graph.microsoft.com/v1.0/deviceManagement/manageddevices
You can reduce the size of the response by selecting only some properties you need
GET https://graph.microsoft.com/v1.0/deviceManagement/manageddevices?$select=id
Then the second call to get detected apps and expand managedDevices
GET https://graph.microsoft.com/v1.0/deviceManagement/detectedApps?$expand=managedDevices
GET https://graph.microsoft.com/v1.0/deviceManagement/detectedApps?$expand=managedDevices($select=id)
Group detected apps from the second call by managed device id and compare them with a list of all devices from the first call to find out which devices have apps.
