To enable the REST API you can use the following starter in your pom.xml:

<dependency>
  <groupId>org.camunda.bpm.springboot</groupId>
  <artifactId>camunda-bpm-spring-boot-starter-rest</artifactId>
  <version>{project-version}</version>
</dependency>

By default the application path is rest, so without any further configuration you can access the api at http://localhost:8080/rest/engine.

Because we use jersey, one can use spring boot’s common application properties.For example, to change the application path, use

spring.jersey.application-path=myapplicationpath

To modify the configuration or register additional resources, one can provide a bean which extends fromorg.camunda.bpm.spring.boot.starter.rest.CamundaJerseyResourceConfig:

@Component
@ApplicationPath("/rest")
public class JerseyConfig extends CamundaJerseyResourceConfig {
  @Override
  protected void registerAdditionalResources() {
    register(...);
  }
}
