Data Tag how to extract the data?

Hi, How do i use the event data from the client in the server? I need to send it to facebook serverside, and Stape says that the Facebook tag automaticllaly send the data from data tag to facebbok, but when i check in events manager i dont see it geting send.

Variables, select New then Data Layer and put the name down in the event data, for last_name it would be last_name

call it “DLV - last_name”

The server has an ‘Event Data’ variable so you can make a variable for the data you want and add that data to the tags you want.
In the event data variable, specify the path to it just like you do on the web in data layer variables.
