Not getting '@odata.type' fields in resposne while fetching App Protection policies

Anil Ranolia 0

Hi, I am making below api calls to fetch the list of app protection policies in a tenant:

Android: https://graph.microsoft.com/beta/deviceAppManagement/androidManagedAppProtections
IOS: https://graph.microsoft.com/beta/deviceAppManagement/iosManagedAppProtections
Windows: https://graph.microsoft.com/beta/deviceAppManagement/mdmWindowsInformationProtectionPolicies

In the response, I am getting the response correctly. But i am not getting '@odata.type' field that tells me what type of policy that is.

Is this intentional or a bug? Also please mention if there is any workaround to get this specific field.

Thank you.

Hello Anil!
My understanding is that when you query a specific entity collection endpoint like /androidManagedAppProtections or /iosManagedAppProtections, Microsoft Graph already knows the exact type being returned, so the @odata.type annotation is intentionally omitted from the response. This is standard OData behavior — the type is only included when the response could contain mixed/derived types (i.e., polymorphic collections).

Possible workarounds to get @odata.type:

Use the generic endpoint — Query the parent collection which returns all policy types together:

GET https://graph.microsoft.com/beta/deviceAppManagement/managedAppPolicies

This returns a mixed collection, so @odata.type will be included for each item.

Infer the type from the endpoint — Since you're already calling type-specific endpoints, you can map the type yourself:

/androidManagedAppProtections → #microsoft.graph.androidManagedAppProtection

/iosManagedAppProtections → #microsoft.graph.iosManagedAppProtection

/mdmWindowsInformationProtectionPolicies → #microsoft.graph.mdmWindowsInformationProtectionPolicy

Request it explicitly via $select (may not work on all beta endpoints, but worth trying):

?$select=id,displayName,@odata.type
