Spring Boot is a popular framework for creating powerful RESTful APIs, and in this tutorial, we will use it to develop a simple API that simulates a credit score rating. The API endpoint we will create will allow a user to retrieve a credit score rating by sending a request to the API. However, it is important to note that we will not be linking up to any actual backend systems to pull a real credit score. Instead, we will use a random number generator to generate the score and return it to the user. Although this API is relatively simple, it will demonstrate the basics of REST API development using Java and Spring Boot. This tutorial will provide a hands-on introduction to building RESTful APIs with Java Spring Boot.
