Is it possible to get the exact hashing algorithm that was used for a previous experiment? I want to analyze behavior of users and segment them based on the experiment variation they would have viewed. For example, we ran a test on two different navigations, and we have click tracking for the nav links, but for the nav link clicks I’d like to classify which variation they would have seen based on their anonymous_id and experiment key.

yes

Do you share the code for the hashing algorithm so I can calculate post-hoc? I found a way around this, but it would help my predicament of joining the GA4 events table on itself

sure, we're open source

ah ty ty, I’m in Big Query so probably can’t use the SDK

true
