using API, we want to retrieve some informations about Web scenarios, like the average response time for the first (and uniq) step.
We retrieve the web scenario information without any problem (using httptest.get).
But to get the average response time, we use the historyGet, but we must set in parameter (itemid) the id of the average response time (I get the itemid in the frontend url).
In other word, I don't understand how is linked the web scenario id to the average download time of the 1st step.
I've also check on database but cannot see the relation.
Thanks for your help
