# Socket.IO Subscribe

## Overview

![The Socket.IO Subscribe Node.](https://2561100106-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Ff6JZovzOqBctA4C1o76u%2Fuploads%2Fgit-blob-2a117cf27d35923860676ea389ff5c97eec3702f%2Fsocketiosubscribenodereal.png?alt=media)

The **Socket.IO Subscribe Node** starts listening to the specific **Socket.IO** event given. This means that the server filters for the desired data with the particular `Namespace` and `Event name`.

**Socket.IO Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **Socket.IO Subscribe** will not show up in the [**Toolbox**](https://docs.incari.com/incari-studio/2023.2/toolbox/overview). Please refer to the [**Plugins Editor**](https://docs.incari.com/incari-studio/2023.2/modules/plugins/communication/socketiomanager) to find out more information.

[**Scope**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2023.2/toolbox/communication/overview.md#scopes): **Project**, **Scene**.
