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.
To navigate to the endpoint declaration from the Endpoints tool window, do one of the following:
Select Jump to source from the endpoint's context menu.
Select the endpoint and press F4.
Double-click the endpoint.
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.
Endpoints marked as deprecated appear with a strikethrough (crossed out).
You can also search for endpoints in Search everywhere. Press Ctrl+Shift+\ and, in the Endpoints tab, start typing a URL. The Endpoints tab is available in Spring, Micronaut, Quarkus, and Ktor projects.
To hide the Endpoints tab from Search Everywhere, open Advanced Settings in the IDE settings (Ctrl+Alt+S) and clear the Show Endpoints tab for relevant projects checkbox.

Item | Description |
|---|---|
Module | Filter endpoints by module or select an external module |
Type | Filter endpoints by type |
Framework | Filter endpoints by framework |
| Configure OpenAPI Sources: Add an external OpenAPI specification (for example, from SwaggerHub) to include endpoints from this specification in the Endpoints tool window and highlight them with a yellow background. In the OpenAPI Specifications window that opens, click For more information, refer to Add a remote OpenAPI specification. |

in the Endpoint details
When you select an endpoint, you can see the details in the dedicated pane. Use 
or 
to show and hide the details pane.
Shows the generated HTTP or gRPC request for the selected endpoint.
If the corresponding server is running, you can submit the request to see the response immediately or open it in a separate HTTP requests file in the editor. For more information, refer to HTTP Client.
Shows the generated OpenAPI specification for the selected endpoints.
You can also generate an OpenAPI specification for an entire module: right-click a module in the Endpoints tool window and select Export Draft of OpenAPI Specification.
To preview the specification in a separate file, click 
.
Provides examples of client code to access the selected endpoint. Use the Frameworks list to select a framework or a language in which you want to show code.
For Retrofit and Ktor, you can also click 
and select Show Boilerplate Code to complete the request sample with all the necessary code elements, such as import statements and HTTP Client instance.
To save the code sample into a file, hover over the code and click . This will save the code into a new scratch file.
Shows the documentation for the selected endpoint. Double-click an endpoint to navigate to its source code.
