How does iOS identify received notification is for MDM?

Question

I want to use MDM to manage number of iOS devices.

According to documentation I do not need anything installed on device. In that case when device receives a notification from APNS server, how will it come to know that this notificaation is for MDM?

Answer 1

Push Notification String: {"aps":{},"mdm":"MagicPushDeviceCode"}.

Answer 2

You need to install at least a root certificate from the MDM-Company (in your case your software / yourself need to deploy the root certificate to the endusers device). As soon as the device has the root certificate installed, you can send some MDM json payloads through APNS.

I think you can deploy the root certificate with many ways including download in safari on your iOS or also with the configuration utility.
