About

python-n26 is a Python 3.6+ library and Command Line Interface to request information from n26 bank accounts. You can use it to check your balance from the terminal or include it in your own Python projects.

Disclaimer: This is an unofficial community project which is not affiliated with N26 GmbH/N26 Inc.

Install

pip3 install n26
wget https://raw.githubusercontent.com/femueller/python-n26/master/n26.yml.example -O ~/.config/n26.yml
# configure username and password
vim ~/.config/n26.yml

Configuration

python-n26 uses container-app-conf to provide different options for configuration. You can place a YAML (n26.yaml or n26.yml) or TOML (n26.toml or n26.tml) configuration file in ./, ~/ or ~/.config/. Have a look at the YAML example and TOML example. If you want to use environment variables:

• N26_USER: username
• N26_PASSWORD: password
• N26_DEVICE_TOKEN: random uuid to identify the device
• N26_LOGIN_DATA_STORE_PATH: optional file path to store login data (recommended for cli usage)
• N26_MFA_TYPE: app will use the paired app as 2 factor authentication, sms will use SMS to the registered number.

Note that when specifying both environment variables as well as a config file and a key is present in both locations the enviroment variable values will be preferred.

Authentication

Device Token

Since 17th of June 2020 N26 requires a device_token to differentiate clients. This requires you to specify the DEVICE_TOKEN config option with a UUID of your choice. To generate a UUID you can use f.ex. one of the following options:

Using python:

python -c 'import uuid; print(uuid.uuid4())'

Using linux built-in tools:

> uuidgen

Using a website: https://www.uuidgenerator.net/

2FA

Since 14th of September 2019 N26 requires a login confirmation (2 factor authentication).

There are two options here:

1. Using the paired phone N26 app to approve login on devices that are not paired. This can be configured by setting app as the mfa_type. You will receive a notification on your phone when you start using this library to request data. python-n26 checks for your login confirmation every 5 seconds. If you fail to approve the login request within 60 seconds an exception is raised.
2. Using a code delivered via SMS to your registered phone number as 2 factor authentication. This can be configured by setting sms as the mfa_type.

If you do not specify a login_data_store_path this login information is only stored in memory. In order to avoid that every CLI command requires a new confirmation, the login data retrieved in the above process can be stored on the file system. Please note that this information must be protected from the eyes of third parties at all costs. You can specify the location to store this data in the Configuration.

Usage

CLI example

> n26 balance
123.45 EUR

Or if using environment variables:

> N26_USER=user N26_PASSWORD=passwd N26_DEVICE_TOKEN=00000000-0000-0000-0000-000000000000 N26_MFA_TYPE=app n26 balance
123.45 EUR

JSON output

If you would like to work with the raw JSON rather than the pretty table layout you can use the global -json parameter:

> n26 -json balance
{
  "id": "12345678-1234-1234-1234-123456789012",
  "physicalBalance": null,
  "availableBalance": 123.45,
  "usableBalance": 123.45,
  "bankBalance": 123.45,
  "iban": "DE12345678901234567890",
  "bic": "NTSBDEB1XXX",
  "bankName": "N26 Bank",
  "seized": false,
  "currency": "EUR",
  "legalEntity": "EU",
  "users": [
    {
      "userId": "12345678-1234-1234-1234-123456789012",
      "userRole": "OWNER"
    }
  ],
  "externalId": {
    "iban": "DE12345678901234567890"
  }
}

API example

from n26.api import Api
api_client = Api()
print(api_client.get_balance())

This is going to use the same mechanism to load configuration as the CLI tool, to specify your own configuration you can use it as:

from n26.api import Api
from n26.config import Config

conf = Config(validate=False)
conf.USERNAME.value = "[email protected]"
conf.PASSWORD.value = "$upersecret"
conf.LOGIN_DATA_STORE_PATH.value = None
conf.MFA_TYPE.value = "app"
conf.validate()

api_client = Api(conf)
print(api_client.get_balance())
