Thanks for your question. Yes, we can use any data layer that is set but we'd always recommend to keep a flat structure for ease of use in Tealium and for the user. However, if you have an existing data layer then if you get in contact with your Account Manager they should be able to help you with some code which can be run in an extension in Tealium to flatten the Universal Variable object for use in Tealium (this will run inside Tealium).
Hi and thanks for quick replay.
What should i use for output, UV is a JSOn object (using the extension to flatten) i tried utag_data but cant se anything in the datalayer,using the google tealium tools and recording, i just started with tealium, worked with opentag and innometrics befor so i know som JS and jQuery coding.
