I need a way to get the UniqueID from a detected target

Hi,

I'm developing an AR aplication with Unity that works with Vuforia, but stores all the data in a external database. 

I'm using Cloud Recognition and a Cloud database to store all the targets.

In order to match the target recognised by the Cloud recogniton with it data (which , as I mention above, is stored in a external database because I'm not using the metadata option of Vuforia) I need to get the UniqueID of the recognised target to get the current data from my database based on this id.

I know that I can get the name of the recognised target but I need and ID that is unique in all cases.
