Development of a REST API for the Rinjani Visitor Application using Extreme Programming

Mount Rinjani National Park on Lombok Island, West Nusa Tenggara, has become a popular ecotourism destination. However, the management of this ecotourism is still not optimal, especially in terms of online marketing efforts. The positive response from tourists to this effort shows great potential for further development. The community needs a separate information system to overcome these problems. This research aims to develop an API for an application called Rinjani Visitor. This API development will use the REST architecture due to its flexibility and scalability, with JSON as the data communication format. The extreme programming method was chosen for system development because it is flexible and adaptive to changing needs. The developed REST API has successfully passed testing with the black box method to test the functionality of each endpoint and obtained satisfactory results for performance testing. This REST API was deployed to Google Cloud, integrated into web and mobile applications, and then released to the public. With an information system like this, it is hoped that the management of the ecotourism business in the Mount Rinjani area can be optimized.
