About data version
In all API methods we use the
dv parameter - the version of the data being sent.
This parameter allows us to maintain API backward compatibility in cases
when a method significantly changes its signature or the signature of its return value.
In that case, we can determine the version of the API used by the client by the value of the dv parameterAt the moment none of our model has had significant changes,
so always use
dv = 1 as the value of this parameter in your queries.
