Here is a quick version that can go with the post Clint suggests.
Add three data sources: timestamp, univar1, univar2
Add a Set Data Values Extension and set it up like:
Set: timestamp To: JS Code -> (new Date()).getTime();
Set: univar1 To: Text -> "ID" (do not use quotes)
Set: univar2 To: Text -> "summ" (do not use quotes)
In the Generic Tag select image in the drop-down. Then paste this into both HTTP and HTTPS lines:
In the static parameters paste this:
Then in the mappings section map:
timestamp -> t
referrer -> r
univar1 -> a1
univar2 -> a2
This should get you there.
Thank you Jared!
One more question:
I want to set a1 and a2 to use dynamic values from js. In this case can I mapp
bookingID(js) -> a1 (where bookingID is already defined)
totalPrice(js) -> a2 (where totalPrice is already defined)
Or I need to still use the Set Data Value Extension?
