Is it possible or I have to use beforeSave event handler.

Hi Akshat,
Yes, you can cancel object creation by throwing an exception from beforeCreate event handler but only if it is a synchronous handler.

What if I use beforeSave event handler?
As I know we don’t have such Data Service event as ‘Save’.
The whole list of events you can find here.
