Python client for EET

Simple and mosty untested implementation of EET (e-trzby) as defined by Czech Financial Administration (http://www.etrzby.cz/) It works with all developer certificates from http://www.etrzby.cz/cs/archiv-technicke-specifikace.

Tested on Python 2.7.11 and 3.4.3

The module depends on:

• lxml
• requests
• pyOpenSSL
• pytz

The API is not stable yet and subject to change.

python setup.py install

import eet

eet_client = eet.EET(CERT_PATH, CERT_PASS, 1, 'pokladna1')
payment = eet_client.create_payment('P12321', 3248, test=False)
payment.set_amount(eet.TAX_BASIC, 1000, 210)
result = eet_client.send_payment(payment)
print (result['fik'])

The code above assumes that you have path to the PKCS12 certificate stored in CERT_PATH and password for this certificate in CERT_PASS.

The general workflow is:

• Create instance of eet.EET
• Create an empty payment report using EET.create_payment()
• Add amount for different tax rates using payment.set_amount()
• send payment using EET.payment(payment)
• If there's any error during the communication with servers, an exception is thrown
• The result is a dict, always containing key 'fik'.
  • If fik is None, the EET servers returned an error, you can query it using keys 'kod' and 'message'
  • If fik is not None, then it contains FIK returned from the servers

The code above sends the payments to the EET Playgroud by default. To use different servers (production), use eet_url parameter in EET constructor.
