Hey, If my understanding is correct, this faq answer is not precise. It mentions hasing the
user id
with the
trackingKey
but I think it hashes the experiment
hashAttribute
(which could or could not be the users id) and the
trackingKey
, am I correct or it always uses the
id
attribute?

agreed, our docs could be more clear on this. Typically (but not necessarily) the
hashAttribute
should be set to be the user_id, session_id, or device_id; but it could be anything uniquely identifiable.
