Referring to LSA Course 7.4, under the chapter Promoting Reuse for the exercise Constructing the Hotel and Hotel Proxy applications,Creating the REST integration interface

-- Instead of the solution specified in the Pega Academy, is it possible to have the below
approach which will avoid creating custom rest services, kindly let know your comments

* Once the email to hotel contacts is triggered, using split for each create individual assignments for
each of the hotel contacts.i.e, 3 assignments for 3 hotel contacts.
* When Hotel Contact login to Hotel Proxy application, Use Pega OOTB API get /assignments to fetch the list of assignments for the respective hotel contacts.
* when the hotel contact submit the booking confirmation use Pega OOTB API post /assignments to
update the case with reservation confirmation.

Thanks,

Dilip
