I have the problem that I have to use the JS and PHP API of Piwik on my site at the same time. Which is in general no problem but each visitor is tracked twice. I'm already pushing the IP with my PHP code but that's obviously not enough. Now I thought I could set a unique VisitorID but it seems that this is not possible in the JS API.
What can I do to get tracked each visitor just once?
Thanks in advance, Martin
