Profile
Profile in response
It is very important to synchronize profile.id
returned in response with the profile id saved on a client side.
When the profile in response is different from the one we have sent that it means that the client should update its
profile.id
and send new one with the next call. If you miss this part then the profile.id
will be recreated with
each call to /track API. That may ruin the whole profile.
