Endpoints tool window
The Endpoints tool window provides an aggregated view of both client and server APIs used in your project for HTTP and WebSocket protocols. The tool window can assist you when developing microservices and backend-frontend communication. It is also helpful for exploring third-party APIs.
Supported frameworks
CLion recognizes endpoints from the following frameworks:
Jakarta EE WebSocket
Java EE WebSocket
JAX-WS
JAX-RS
JAX-RS Client
MicroProfile Rest Client
Spring Feign Client
Spring MVC
Spring Reactive WebSocket
Spring RestTemplate
Spring WS
Spring WebClient
Micronaut HTTP Controllers
Micronaut HTTP Client
Micronaut Management Endpoints
Micronaut WebSocket
Ktor
Helidon MP
Helidon SE
Quarkus
OpenAPI 3
Swagger 2
WSDL
Retrofit 2
OkHttp 3+
You can also navigate from the Endpoints tool window or from endpoint usages to the relevant endpoint declaration using the Go to Declaration action Ctrl+B or Ctrl+Click.
In the Endpoints tool window, you can filter the list of endpoints by module, type, and framework. To list endpoints from external sources (for example, from remote OpenAPI specifications), select External under Module.
