This is exactly what we are trying to do also, our third party is an affiliate tracker, so I don't think Google Analytics is what is in mind with what Iminardo is talking about, or for what we need either.
We need to pull more info like the order info you've mentioned on the confirm page but the regonline coding is obscured or hidden (for lack of better words). Our situation also involves trying to track registration types as they have different price points - as well as when clients select multiple tickets. So far as we can tell with the generic coding, it will only pull one type - maybe we have to do a "when amount is > or < ..." type of calculation? I'm a bit out of my realm here! An example of our 3rd party "simple as pasting a code" is as follows for only one level of ticket:

So how to get the report if we have registration type denoting different ticket/price levels? How do we also capture multiple tickets? Can the regonline administrator reply as to if it is possible to write the coding so that it points to variables found in the confirmation page?
Thanks in advance!!
