Introduction

A brief introduction to real-time data streaming with Benzinga’s WebSocket API.

Welcome to the Benzinga WebSocket API documentation. This guide will help you get started with accessing Benzinga’s real-time data streams, enabling you to subscribe to continuous updates on financial data, including live market quotes, trades, news, and other key insights.

WebSocket Endpoint

All WebSocket connections can be established using the following endpoint:

wss://api.benzinga.com

Authentication

The Benzinga WebSocket API requires bearer authentication. When initiating a WebSocket connection, include your API token in the connection URL as a query parameter in the following format: you must include your API token in the token query param in the format token: <token>.

Refer to the Authentication page for more information on obtaining and managing your API token.

Subscribing to Streams

Once connected, you can subscribe to specific data streams based on your requirements, such as stock quotes, trade data, or news updates. Each subscription requires a unique identifier and specific parameters depending on the data type.

Example Subscription Message

To subscribe to a live stock quote stream, send a JSON message formatted as follows:

{
  "action": "subscribe",
  "symbol": "AAPL",
  "type": "quote"
}

Rate Limiting

Please note that the Benzinga API has rate limits to prevent abuse and ensure service stability. Only 1 connection per API token is allowed at a time. If you exceed the rate limit, you will receive an error response.
