DTM: Event Based Rules: Serialize from value
Hi,
I have created some Event Based Rules to track critical conversion activities. Currently the Custom Event Variables I with these rules are set to "Record Once Per Visit".
My preference is to record these events once per Visitor.
I see there is another option to "Use Event ID" and I can see an option in my Event Based Rules to "Serialize from value".
How do I use this option?
I would like serialize using the "Marketing Cloud Visitor ID" (MCVID). What do I type into that box? If it helps, I'm capturing the MCVID in an eVar.
Thanks,
Ali
