Application of Rest Api Technology in Android-Based Beauty Salon Service Reservation System

Abstract

The beauty business is experiencing rapid growth along with the changing times, where almost all activities now adopt digital technology. This transformation has had a significant impact on the beauty business world, especially in salons like Elsa Eyelash Salon. Although some salons have switched to online booking, there are still some that use a manual system. To overcome this challenge, this research develops an Android-based reservation system application with Rest API. The development method applied is the waterfall method, with an emphasis on requirements analysis, design, implementation, and testing. The implementation results show an intuitive user interface, making it easier for customers to make reservations online. Functional tests were conducted using the black box testing method, which successfully identified potential bugs before the application was widely used. The hope is that this application can improve the quality of service in beauty salons and provide a better customer experience. Thus, this application is expected to be an effective solution to support the development of the beauty industry in the future.
