Request Body

Name Type Description
authentication

AuthenticationMechanism

The authentication mechanism used by the device.
capabilities

DeviceCapabilities

The set of capabilities of the device. For example, if this device is an edge device or not.

connectionStateUpdatedTime

string

The date and time the connection state was last updated.
deviceId

string

The unique identifier of the device.
deviceScope

string
