Cross device user matching

How can I identify and match a user across different devices?

For example, suppose someone sees my Google ad on their laptop but later completes a calendar booking using their mobile phone from my website. In this case, since I am using Stape Store, how can I identify that it is the same person and match the booking with the original Google Click ID (GCLID)?

Hi @Rosa_Paula

To support cross-device tracking, you need to create a user master cookie. This ID is typically linked to the user’s account and as soon as the user switches devices and log in into their account, you will be able to restore the cookies on the new device based on that master cookie.

This is the most reliable solution at the moment, but yes, unfortunately, it requires some additional coding on your part.
