Atomx User Sync / Cookie Sync | Atomx is now supporting User Syncing. It’s an increasingly common technical process in digital advertising that enables platforms to identify the same user with an anonymous identifier. What exactly happens? The matching process of the SSP cookie ID to the DSP cookie ID happens through a parallel process to serving ads called ‘cookie syncing’. A cookie synchronization is necessary because as a standard security process, web servers can only request cookies that are set to their own domain. Since the SSP sits between the user and all the DSP bidders in a real-time auction, the DSP needs a way to identify the users it is looking for.
If you want to get the User Sync process going with Atomx, please contact your network manager. More Details on Atomx User Syncing you find in this documentation -> https://wiki.atomx.com/usersync
