App Configuration in JSON Format

Rudy_Ooms_MVP By the way: it also does not run, when i try to only add one configuration item like this:

{
    "kind": "androidenterprise#managedConfiguration",
    "productId": "app:com.microsoft.emmx",
    "managedProperty": [
		{
            "key": "com.microsoft.intune.mam.managedbrowser.homepage",
            "valueString": "https://www.sample.com"
        }
    ]
}
