You can choose HTTP methods, depending upon the nature of the HTTP call, and make a request to it. Please refer to all the methods while you use it. It will then create a WebClient object and also allow you to customize your call with several methods that it offers. In step 3, we have created an instance of WebClient and initialized it by using the WebClient builder. public interface ContentService ', id).retrieve().bodyToMono(Post.class) Create an interface with a method that will return the response from the REST call. Add Spring WebFlux dependency to you POM.XML

If you are using any other build tool, please find the dependency on the Internet, as they should be easily available. Note that I would be using a Maven build tool to show the demo. So, make sure you are using Spring WebFlux already if you plan to use WebClient to make API calls. The main advantage of using the WebClient is that it is reactive, as it uses Webflux and is also non-blocking by nature and the response will always be returned in either Mono or Flux. You can leverage any of these methods to make calls to the external service asynchronously. This includes methods like GET, POST, PUT, PATCH, DELETE, and OPTIONS. WebClient is simply an interface that offers methods to make calls to rest services. It was introduced in Spring 5 as part of the web reactive framework that helps build reactive and non-blocking web applications. If you are using Spring WebFlux, you can choose to use WebClient to call external rest services. In this article, we will talk about the Spring Boot WebClient.
