APM call Airwatch API To check device compliance

Hi, I am trying to do this exact use case with a device certificate and serial number in the certificate, but I cannot find which variable to use to query the AW API. Does anyone have any insight into which variable to use for this?

I have been referred to this link but it states it is using the UDID and not the serial number.

session.client.unique_id = Contains the UDID* of the iOS device
