# REST API Usage

## Configuration

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

Sample configuration:

``` json
    "api_server": {
        "enabled": true,
        "listen_ip_address": "127.0.0.1",
        "listen_port": 8080,
        "verbosity": "info",
        "jwt_secret_key": "somethingrandom",
        "CORS_origins": [],
        "username": "Freqtrader",
        "password": "SuperSecret1!"
    },
```

!!! Danger "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.

!!! Danger "Password selection"
    Please make sure to select a very strong, unique password to protect your bot from unauthorized access.

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:

``` output
{"status":"pong"}
```

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

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

``` python
import secrets
secrets.token_hex()
```

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

### 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.

``` json
    "api_server": {
        "enabled": true,
        "listen_ip_address": "0.0.0.0",
        "listen_port": 8080
    },
```

Add the following to your docker command:

``` bash
  -p 127.0.0.1:8080:8080
```

A complete sample-command may then look as follows:

```bash
docker run -d \
  --name freqtrade \
  -v ~/.freqtrade/config.json:/freqtrade/config.json \
  -v ~/.freqtrade/user_data/:/freqtrade/user_data \
  -v ~/.freqtrade/tradesv3.sqlite:/freqtrade/tradesv3.sqlite \
  -p 127.0.0.1:8080:8080 \
  freqtrade trade --db-url sqlite:///tradesv3.sqlite --strategy MyAwesomeStrategy
```

!!! Danger "Security warning"
    By using `-p 8080:8080` the API is available to everyone connecting to the server under the correct port, so others may be able to control your bot.

## 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.

``` bash
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

``` json
{
    "api_server": {
        "enabled": true,
        "listen_ip_address": "0.0.0.0",
        "listen_port": 8080
    }
}
```

``` bash
python3 scripts/rest_client.py --config rest_config.json <command> [optional parameters]
```

## 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.

``` bash
> 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"}

> access_token="eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE1ODkxMTk2ODEsIm5iZiI6MTU4OTExOTY4MSwianRpIjoiMmEwYmY0NWUtMjhmOS00YTUzLTlmNzItMmM5ZWVlYThkNzc2IiwiZXhwIjoxNTg5MTIwNTgxLCJpZGVudGl0eSI6eyJ1IjoiRnJlcXRyYWRlciJ9LCJmcmVzaCI6ZmFsc2UsInR5cGUiOiJhY2Nlc3MifQ.qt6MAXYIa-l556OM7arBvYJ0SDI9J8bIk3_glDujF5g"
# 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:

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

## CORS

All web-based frontends are subject to [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/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 configure this themselves via the `CORS_origins` configuration setting.
It consists of a list of allowed sites 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:

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

!!! 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.
