As in Create Script Templates :
Auth0 calls the Get User script before the Create script. Be sure to implement both database action scripts if you are creating new users. When the script finishes execution, the Login script runs to verify that the user was created successfully.
However, I am integrating with my app via restful calls, I need not to call Login after create, is that possible? or at least, no know the caller inside Login if its by user or after create?
