Tracking Pixel Question (need help)?

Right now I have 10 websites setup through Piwik. All these websites are sending traffic to another on another domain. Well is there a way I can just place one pixel on our success page on this other domain. Therefore tracking all the conversions from these other sites (coming from different domains)?

I am not sure if there is a way to do this. Or maybe I can add multiple numbers to idsite=3 somehow. Or add something there. Vs placing all these pixels on ours success page which would take forever.

Anyone?

Yes you can use several javascript trackers with different idsites

I figured out that you could do it, but I am having an issue look at 301 Moved Permanently.
