Subject: Re: create/update differentiation in eagle service API
Hi Murali,
There is no easy way to distinguish create and update. But looks it is not that
important to know if policy is created or updated. If we do want to know if it
is created or updated, we can look at the policy¹s history and the first change
must be create.
Thanks
Edward
