Integrate Tookan in Karenderia

Hello, Currently we have a code bought in codecanyon called Karenderia. This code is developed for multi-restaurant and also has modules to be added. One of the modules that we want to modify is the one that manages the deliveries' shipments. This module is poor and does not fulfill the functions we require. The specific module is this [login to view URL] that does not work without the main engine of the website to which it connects by API which is this [login to view URL] We want to integrate tookan [login to view URL] and eliminate the current one so that it is in charge of managing all the receipt of orders.
