What parameters should I use ?
loopcd (for all analytics platforms including Adobe, Google or Piano Analytics)using the utm_content parameter in substitution is possible (only for Google Analytics)
URL template
Just add the following string at the end of the destination URL &loopcd=DIh|${HAWK_LINE_ID}. If Adloop is the only tracking template : ?loopcd=DIh|${HAWK_LINE_ID}. If you opt for the utm_content , use this value : &utm_content=DIh|${HAWK_LINE_ID}
Shoud I use both adlcoid & utm_content ?
No, choose one.
