# Endpoints tool window

> **TL;DR**
> `View | Tool Windows | Endpoints`

Procedure: Enable the HTTP Client plugin

This functionality relies on the [HTTP Client](https://plugins.jetbrains.com/plugin/13121-http-client)  plugin, which  is bundled and enabled in IntelliJ IDEA   by default. If the relevant features are not available, make sure that you did not disable the plugin.    For more information, refer to [Open plugin settings](managing-plugins.html#open-plugin-settings).

1. Press `Ctrl+Alt+S` (Windows), `⌘ Comma` (macOS), `⌘ Comma` (IntelliJ IDEA Classic (macOS)), `⌘ Comma` (macOS System Shortcuts), `Ctrl+Alt+S` (XWin), `Ctrl+Alt+S` (GNOME), `Ctrl+Alt+S` (KDE), `Ctrl+Alt+S` (Emacs), `Ctrl+Alt+S` (Sublime Text), `⌘ Comma` (Sublime Text (macOS)), `Ctrl+Alt+S` (NetBeans), `Ctrl+Alt+S` (Visual Studio), `⌘ Comma` (Visual Studio (macOS)), `Ctrl+Alt+S` (Eclipse), `⌘ Comma` (Eclipse (macOS)) to open settings and then select `Plugins`.

2. Open the Installed tab, find the HTTP Client plugin, and select the checkbox next to the plugin name.

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.

> **Note:**
> The Endpoints tool window is available in any project, but it lists endpoints only when the project contains one of the [supported frameworks](#supported-frameworks). If the tool window is not shown, find it through [Search Everywhere](searching-everywhere.html) or open it from `View | Tool Windows | Endpoints`.

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` (Windows), `⌘ ↓` (macOS), `F4` (IntelliJ IDEA Classic (macOS)), `F4` (macOS System Shortcuts), `F4` (XWin), `F4` (GNOME), `F4` (KDE), `F4` (Emacs), `F4` (Sublime Text), `F4` (Sublime Text (macOS)), `F4` (NetBeans), `F4` (Visual Studio), `⌘ ↓` (Visual Studio (macOS)), `F12` (Eclipse), `F3` (Eclipse (macOS)).

* 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](openapi.html#remote-spec))  , select  External  under  Module  .

Endpoints marked as deprecated appear with a strikethrough (crossed out).

| ![the Configure OpenAPI Sources icon](https://resources.jetbrains.com.cn/help/img/idea/2026.2/product.icons.expui.openApi.svg) |    > **Note:** > The action is available if the [OpenAPI Specifications](https://plugins.jetbrains.com/plugin/14394-openapi-specifications) plugin is installed and enabled.      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 ![the Add button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.add.svg) in the Remote Specifications list, and specify the URL of an OpenAPI specification file or find an OpenAPI specification on [SwaggerHub](https://app.swaggerhub.com/). This also adds URLs defined in the specification to [code completion](auto-completing-code.html).

## Endpoint details

When you select an endpoint, you can see the details in the dedicated pane. Use ![the Show Side Panel icon](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app-client.expui.general.previewHorizontally.svg) or ![](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app-client.expui.general.previewVertically.svg) to show and hide the details pane.

HTTP Client:

Shows the generated HTTP or [gRPC](http-client-in-product-code-editor.html#grpc-requests)  request for the selected endpoint.

If the corresponding server is running, you can click Submit Request to see the response immediately or Open in Editor to edit it in a separate HTTP requests file in the editor. For more information, refer to [HTTP Client](http-client-in-product-code-editor.html).

![Endpoints tool window: HTTP Client tab](https://resources.jetbrains.com.cn/help/img/idea/2026.2/endpoints-tool-window-http.png)

OpenAPI:

> **Note:**
> The tab is available if the [OpenAPI
> Specifications](https://plugins.jetbrains.com/plugin/14394-openapi-specifications) plugin is installed and enabled.
>
>
>
> For [gRPC](http-client-in-product-code-editor.html#grpc-requests) requests, the tab is not enabled because gRPC APIs are defined through .proto files.

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.

![Endpoints tool window: OpenAPI tab](https://resources.jetbrains.com.cn/help/img/idea/2026.2/endpoints-tool-window-openapi.png)

To [preview the specification](openapi.html#preview-api) in a separate file, click ![The Export Draft of OpenAPI Specification button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app-client.expui.general.save.svg).

Documentation:

Shows the documentation for the selected endpoint. Double-click an endpoint to navigate to its source code.

![Endpoints tool window: Documentation tab](https://resources.jetbrains.com.cn/help/img/idea/2026.2/endpoints-tool-window-options.png)

Examples:

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 ![the Show icon](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app-client.expui.general.show.svg) and select Show Boilerplate Code to complete the request sample with all the necessary code elements, such as import statements and HTTP Client instance.

![Endpoints tool window: Example tab](https://resources.jetbrains.com.cn/help/img/idea/2026.2/ij_endpoints_client_examples.png)

To save the code sample into a file, hover over the code and click ![Save icon](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app-client.expui.general.save.svg). This will save the code into a new scratch file.

## Services diagram

IntelliJ IDEA provides a diagram to show the interactions between microservices. In the Endpoints tool window, click ![Service Diagram icon](https://resources.jetbrains.com.cn/help/img/idea/2026.2/microservices-ui.icons.expui.diagramAction.svg).
