Hello, I received a tutorial from
Thanks to the guys at voluum, they took some time creating this for me and I thought I would share. I have not tried this yet, so please check for yourself.
Voluum Support,

I made a general tutorial for you, please take a look and adjust it for your needs. If something is unclear let me know.
Let’s say we’ve got a campaign called ‘Normal Campaign’, and on the lander, there’s a backbutton script – preventing the user from leaving our Landing Page, and instead redirecting him to another landing page.
If he converts from the second landing page, we want to know, which campaign/landing page he originally entered.
So, we have to create a secondary Campaign, and a secondary Traffic Source. Let’s call the Campaign ‘After Backbutton Campaign’, and the traffic source ‘Traffic Source Especially For Backbutton’.
The ‘After Backbutton Campaign’ has to be technically set up as one of the offers for ‘Normal Campaign’. In general, our traffic flow should look like this:

Let’s jump right into it and for a good start create the ‘Traffic Source Especially For Backbutton’’ as follows:

As you see, we have defined 2 custom variables, and that’s how we are going to pass the data from one campaign to another.
Now, let’s create ‘After Backbutton Campaign’:

Now we have to create an Offer that will only redirect the user to the ‘After Backbutton Campaign’, let’s call it ‘BackButtonRedirect’.

Please notice that we have campaign.id={campaign.id}&lander.id={lander.id} in the URL pointing to ‘After Backbutton Campaign’.
Now, let’s finally properly configure our ‘Normal Campaign’:

That’s it. With all that configured properly, while redirecting user from one campaign to another, Voluum will append that first campaign’s ID and lander ID to the URL, and the second campaign will ‘catch’ this information and show it in reports.
This way, you will be able to know, where the BackButton Redirect script is the most effective.
To see it in reports, adjust your report groupings accordingly:

And that's it. Enjoy
WOW!
This came in right on time for me.
I will be testing this and see how it goes.
Thanks a lot webdev.
Wondering why they are not passing the clickid though?
Thanks very much webdev for taking the time to post this! Quite a few people have asked about how to do this. Next time instead of explaining with words I could just refer them to your tutorial.
