i have and existing e-commerce website/mobile app + delivery app, developed with Laravel and java, all apps and website are currently working just fine. I need an API to call my current delivery function to add a new order from any other e-commerce websites. the other websites will use the api it will get from the server the available areas and times for delivery, then after completing the purchase it will send the order information and delivery time and address back to the server. The data has to be encrypted and has authenticated token.
there are now documentation but the functions and classes are organized neatly, and it will be easy for a Laravel expert to manage.
