Example

Justtag Group is a European, privacy focused DMP and segment provider. Having a leading position in Poland and growing presence in the CEE region, we created Just ID - an alternative ID solution, designed to respect users’ privacy choices which doesn’t rely on 3rd party cookies. Our aim is to help Publishers and Advertisers to recognize users across various environments and enable ad-tech market players with a smooth transition into post 3rd party cookie era.

Just ID Modes

  • BASIC - In this mode we rely on Justtag library that already exists on publisher page. Typicaly that library expose global variable called __atm

  • COMBINED - Just ID generation process may differ between various cases depends on publishers. This mode combines our js library with prebid for ease of integration

If you have any questions about Just ID, please reach out by emailing prebid@justtag.com.
