Plugin

Stream Deck provides an API for distributing plugins as native console apps, for example those written in C++, C#, etc, with communication being handled by a dedicated WebSocket connection.

warning

Creating native plugins is an advanced technique, and is not recommended. Instead, consider using the Stream Deck SDK with Node.js native addons.

Registration

In order to establish a connection with Stream Deck, your plugin must first register itself using a unique identifier. The information required to establish the connection is provided as a command line parameter, along with:

Parameter	Description
`-port`	The port the WebSocket is running on.
`-info`	A serialized JSON string that contains information about Stream Deck, Stream Deck devices, and your plugin. See RegistrationInfo.
`-pluginUUID`	Your plugin's unique registration identifier.
`‑registerEvent`	Name of the registration event.

Upon startup, your plugin must connect to the WebSocket on the specified -port, and send a registration message as a JSON serialized string in the following format:

Registration event type

type RegisterEvent = {
	event: string; // -registerEvent parameter
	uuid: string; // -pluginUUID parameter
};

RegistrationInfo

Information about the Stream Deck application, the plugin, the user's operating system, user's Stream Deck devices, etc.
