What is FTX Websocket API?

FTX Websocket API is a tool that allows developers to access real-time market data and trading information from the FTX exchange. The API is built using websockets, which are a more efficient way of transmitting data compared to traditional REST APIs. With FTX websocket API, developers can create custom trading bots, market analysis tools, and much more.

Why Use FTX Websocket API?

There are several benefits to using FTX websocket API in your projects:

  1. Real-time data: With FTX websocket API, you can access real-time market data and trading information, which is crucial for trading strategies.
  2. Efficiency: Websockets are more efficient than traditional REST APIs, as they allow for real-time data transmission without the need for constant requests and responses.
  3. Customization: FTX websocket API allows for customization of data streams, so you can tailor the data you receive to your specific needs.

Getting Started with FTX Websocket API and Python

Before you can start using FTX websocket API with Python, you will need to set up your development environment. Here are the steps you need to follow:

Step 1: Install Python

If you don’t already have Python installed on your system, you can download it from the official website. Make sure to install the latest version of Python.

Step 2: Install Required Libraries

You will need to install several Python libraries to use FTX websocket API. These include:

  • websockets: This library provides a simple way to create websockets in Python.
  • requests: This library is used to send HTTP requests to the FTX API.
  • json: This library is used to parse JSON data received from the FTX API.

You can install these libraries using pip:

pip install websockets requests json

Step 3: Create an API Key on FTX

You will need to create an API key on FTX to access the websocket API. To do this, log in to your FTX account and navigate to the API tab. Click on “Create API key” and follow the on-screen instructions.

Step 4: Connect to the FTX Websocket API

Once you have set up your development environment and created an API key on FTX, you can start connecting to the websocket API. Here is a basic Python script that connects to the FTX websocket API:

import asyncioimport websocketsimport json
async def connect():uri = "wss://ftx.com/ws/"async with websockets.connect(uri) as websocket:subscribe_msg = {"op": "subscribe", "channel": "ticker", "market": "BTC-PERP"}await websocket.send(json.dumps(subscribe_msg))while True:response = await websocket.recv()print(response)
asyncio.get_event_loop().run_until_complete(connect())

This script connects to the FTX websocket API and subscribes to the ticker channel for the BTC-PERP market. The script then waits for incoming data and prints it to the console.

FTX Websocket API Channels

FTX websocket API supports several channels that developers can subscribe to. Here are the main channels:

  • ticker: Provides real-time ticker data for a specific market.
  • trades: Provides real-time trade data for a specific market.
  • orderbook: Provides real-time order book data for a specific market.
  • fills: Provides real-time fill data for a specific account.
  • orders: Provides real-time order data for a specific account.

Developers can subscribe to these channels by sending a subscribe message to the websocket API.

FTX Websocket API Authentication

To access private data on FTX websocket API, such as account information and orders, you will need to authenticate your requests. Here is an example Python script that connects to the FTX websocket API and authenticates:

import asyncioimport websocketsimport jsonimport hmacimport hashlibimport time
async def connect(api_key, api_secret):ts = int(time.time() * 1000)prehash = f'{ts}websocket_login'signature = hmac.new(api_secret.encode('utf-8'), prehash.encode('utf-8'), hashlib.sha256).hexdigest()auth_payload = {"args": {"key": api_key,"sign": signature,"time": ts},"op": "login"}
async with websockets.connect("wss://ftx.com/ws/") as websocket:await websocket.send(json.dumps(auth_payload))while True:response = await websocket.recv()print(response)
asyncio.get_event_loop().run_until_complete(connect(api_key="your_api_key", api_secret="your_api_secret"))

This script connects to the FTX websocket API and authenticates using an API key and secret. The script creates a signature using HMAC-SHA256 and sends an authentication message to the API. The script then waits for incoming data and prints it to the console.

FTX Websocket API Limitations

While FTX websocket API is a powerful tool for developers, it does have some limitations. Here are some of the main limitations:

  • Data rate limits: FTX websocket API has data rate limits that restrict the amount of data you can receive in a given time period.
  • Connection limits: FTX websocket API has connection limits that restrict the number of connections you can have to the API at the same time.
  • Market coverage: FTX websocket API does not support all markets on the FTX exchange.

Developers should keep these limitations in mind when using FTX websocket API in their projects.
