• Authentication: Header (Bearer / API Key) or Query Parameter — stored as n8n credentials
• Extra query parameters: Add any number of key-value pairs appended to the URL
• Auto-reconnect: Configurable interval and max attempt limit (0 = unlimited)
• Initial message: Send a payload immediately after connecting
• Return WS resource: Expose the raw WebSocket object for sending reply messages
