REST API & FreqUI

FreqUI

Freqtrade provides a builtin webserver, which can serve FreqUI, the freqtrade UI.

By default, the UI is not included in the installation (except for docker images), and must be installed explicitly with freqtrade install-ui. This same command can also be used to update freqUI, should there be a new release.

Once the bot is started in trade / dry-run mode (with freqtrade trade) - the UI will be available under the configured port below (usually http://127.0.0.1:8080).

Alpha release

FreqUI is still considered an alpha release - if you encounter bugs or inconsistencies please open a FreqUI issue.

developers

Developers should not use this method, but instead use the method described in the freqUI repository to get the source-code of freqUI.

Configuration

Enable the rest API by adding the api_server section to your configuration and setting api_server.enabled to true.

Sample configuration:

    "api_server": {
        "enabled": true,
        "listen_ip_address": "127.0.0.1",
        "listen_port": 8080,
        "verbosity": "error",
        "enable_openapi": false,
        "jwt_secret_key": "somethingrandom",
        "CORS_origins": [],
        "username": "Freqtrader",
        "password": "SuperSecret1!",
        "ws_token": "sercet_Ws_t0ken"
    },

Security warning

By default, the configuration listens on localhost only (so it's not reachable from other systems). We strongly recommend to not expose this API to the internet and choose a strong, unique password, since others will potentially be able to control your bot.

API/UI Access on a remote servers

If you're running on a VPS, you should consider using either a ssh tunnel, or setup a VPN (openVPN, wireguard) to connect to your bot. This will ensure that freqUI is not directly exposed to the internet, which is not recommended for security reasons (freqUI does not support https out of the box). Setup of these tools is not part of this tutorial, however many good tutorials can be found on the internet.

You can then access the API by going to http://127.0.0.1:8080/api/v1/ping in a browser to check if the API is running correctly. This should return the response:

{"status":"pong"}

All other endpoints return sensitive info and require authentication and are therefore not available through a web browser.

Security

To generate a secure password, best use a password manager, or use the below code.

import secrets
secrets.token_hex()

JWT token

Use the same method to also generate a JWT secret key (jwt_secret_key).

Password selection

Please make sure to select a very strong, unique password to protect your bot from unauthorized access. Also change jwt_secret_key to something random (no need to remember this, but it'll be used to encrypt your session, so it better be something unique!).

Configuration with docker

If you run your bot using docker, you'll need to have the bot listen to incoming connections. The security is then handled by docker.

    "api_server": {
        "enabled": true,
        "listen_ip_address": "0.0.0.0",
        "listen_port": 8080,
        "username": "Freqtrader",
        "password": "SuperSecret1!",
        //...
    },

Make sure that the following 2 lines are available in your docker-compose file:

    ports:
      - "127.0.0.1:8080:8080"

Security warning

By using 8080:8080 in the docker port mapping, the API will be available to everyone connecting to the server under the correct port, so others may be able to control your bot.

Rest API

Consuming the API

You can consume the API by using the script scripts/rest_client.py. The client script only requires the requests module, so Freqtrade does not need to be installed on the system.

python3 scripts/rest_client.py <command> [optional parameters]

By default, the script assumes 127.0.0.1 (localhost) and port 8080 to be used, however you can specify a configuration file to override this behaviour.

Minimalistic client config

{
    "api_server": {
        "enabled": true,
        "listen_ip_address": "0.0.0.0",
        "listen_port": 8080,
        "username": "Freqtrader",
        "password": "SuperSecret1!",
        //...
    }
}

Message WebSocket

The API Server includes a websocket endpoint for subscribing to RPC messages from the freqtrade Bot. This can be used to consume real-time data from your bot, such as entry/exit fill messages, whitelist changes, populated indicators for pairs, and more.

This is also used to setup Producer/Consumer mode in Freqtrade.

Assuming your rest API is set to 127.0.0.1 on port 8080, the endpoint is available at http://localhost:8080/api/v1/message/ws.

To access the websocket endpoint, the ws_token is required as a query parameter in the endpoint URL.

To generate a safe ws_token you can run the following code:

>>> import secrets
>>> secrets.token_urlsafe(25)
'hZ-y58LXyX_HZ8O1cJzVyN6ePWrLpNQv4Q'

You would then add that token under ws_token in your api_server config. Like so:

"api_server": {
    "enabled": true,
    "listen_ip_address": "127.0.0.1",
    "listen_port": 8080,
    "verbosity": "error",
    "enable_openapi": false,
    "jwt_secret_key": "somethingrandom",
    "CORS_origins": [],
    "username": "Freqtrader",
    "password": "SuperSecret1!",
    "ws_token": "hZ-y58LXyX_HZ8O1cJzVyN6ePWrLpNQv4Q" // <-----
},

You can now connect to the endpoint at http://localhost:8080/api/v1/message/ws?token=hZ-y58LXyX_HZ8O1cJzVyN6ePWrLpNQv4Q.

Reuse of example tokens

Please do not use the above example token. To make sure you are secure, generate a completely new token.

Using the WebSocket

Once connected to the WebSocket, the bot will broadcast RPC messages to anyone who is subscribed to them. To subscribe to a list of messages, you must send a JSON request through the WebSocket like the one below. The data key must be a list of message type strings.

{
  "type": "subscribe",
  "data": ["whitelist", "analyzed_df"] // A list of string message types
}

For a list of message types, please refer to the RPCMessageType enum in freqtrade/enums/rpcmessagetype.py

Now anytime those types of RPC messages are sent in the bot, you will receive them through the WebSocket as long as the connection is active. They typically take the same form as the request:

{
  "type": "analyzed_df",
  "data": {
      "key": ["NEO/BTC", "5m", "spot"],
      "df": {}, // The dataframe
      "la": "2022-09-08 22:14:41.457786+00:00"
  }
}

Reverse Proxy setup

When using Nginx, the following configuration is required for WebSockets to work (Note this configuration is incomplete, it's missing some information and can not be used as is):

Please make sure to replace <freqtrade_listen_ip> (and the subsequent port) with the IP and Port matching your configuration/setup.

http {
    map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
    }

    #...

    server {
        #...

        location / {
            proxy_http_version 1.1;
            proxy_pass http://<freqtrade_listen_ip>:8080;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
            proxy_set_header Host $host;
        }
    }
}

To properly configure your reverse proxy (securely), please consult it's documentation for proxying websockets.

  • Traefik: Traefik supports websockets out of the box, see the documentation
  • Caddy: Caddy v2 supports websockets out of the box, see the documentation

SSL certificates

You can use tools like certbot to setup ssl certificates to access your bot's UI through encrypted connection by using any fo the above reverse proxies. While this will protect your data in transit, we do not recommend to run the freqtrade API outside of your private network (VPN, SSH tunnel).

OpenAPI interface

To enable the builtin openAPI interface (Swagger UI), specify "enable_openapi": true in the api_server configuration. This will enable the Swagger UI at the /docs endpoint. By default, that's running at http://localhost:8080/docs - but it'll depend on your settings.

Advanced API usage using JWT tokens

Note

The below should be done in an application (a Freqtrade REST API client, which fetches info via API), and is not intended to be used on a regular basis.

Freqtrade's REST API also offers JWT (JSON Web Tokens). You can login using the following command, and subsequently use the resulting access_token.

> curl -X POST --user Freqtrader http://localhost:8080/api/v1/token/login
{"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk2ODEsIm5iZiI6MTU4OTExOTY4MSwianRpIjoiMmEwYmY0NWUtMjhmOS00YTUzLTlmNzItMmM5ZWVlYThkNzc2IiwiZXhwIjoxNTg5MTIwNTgxLCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.qt6MAXYIa-l556OM7arBvYJ0SDI9J8bIk3_glDujF5g","refresh_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk2ODEsIm5iZiI6MTU4OTExOTY4MSwianRpIjoiZWQ1ZWI3YjAtYjMwMy00YzAyLTg2N2MtNWViMjIxNWQ2YTMxIiwiZXhwIjoxNTkxNzExNjgxLCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJ0eXBlIjoicmVmcmVzaCJ9.d1AT_jYICyTAjD0fiQAr52rkRqtxCjUGEMwlNuuzgNQ"}

# Use access_token for authentication
> curl -X GET --header "Authorization: Bearer ${access_token}" http://localhost:8080/api/v1/count

Since the access token has a short timeout (15 min) - the token/refresh request should be used periodically to get a fresh access token:

> curl -X POST --header "Authorization: Bearer ${refresh_token}"http://localhost:8080/api/v1/token/refresh
{"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk5NzQsIm5iZiI6MTU4OTExOTk3NCwianRpIjoiMDBjNTlhMWUtMjBmYS00ZTk0LTliZjAtNWQwNTg2MTdiZDIyIiwiZXhwIjoxNTg5MTIwODc0LCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.1seHlII3WprjjclY6DpRhen0rqdF4j6jbvxIhUFaSbs"}

CORS

This whole section is only necessary in cross-origin cases (where you multiple bot API's running on localhost:8081, localhost:8082, ...), and want to combine them into one FreqUI instance.

Technical explanation

All web-based front-ends are subject to CORS - Cross-Origin Resource Sharing. Since most of the requests to the Freqtrade API must be authenticated, a proper CORS policy is key to avoid security problems. Also, the standard disallows * CORS policies for requests with credentials, so this setting must be set appropriately.

Users can allow access from different origin URL's to the bot API via the CORS_origins configuration setting. It consists of a list of allowed URL's that are allowed to consume resources from the bot's API.

Assuming your application is deployed as https://frequi.freqtrade.io/home/ - this would mean that the following configuration becomes necessary:

{
    //...
    "jwt_secret_key": "somethingrandom",
    "CORS_origins": ["https://frequi.freqtrade.io"],
    //...
}

In the following (pretty common) case, FreqUI is accessible on http://localhost:8080/trade (this is what you see in your navbar when navigating to freqUI). freqUI url

The correct configuration for this case is http://localhost:8080 - the main part of the URL including the port.

{
    //...
    "jwt_secret_key": "somethingrandom",
    "CORS_origins": ["http://localhost:8080"],
    //...
}

Note

We strongly recommend to also set jwt_secret_key to something random and known only to yourself to avoid unauthorized access to your bot.
