Python EET API

Simple to use and mostly secure (mainly pedantic) API for Czech EET Gate.

Instalation

pip install ...

Usage

Basic usage with single request

from eet import invoices, helpers

cert_text = b'''
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
'''

key_text = b'''
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
'''

# prepare certificate and private key
cert = helpers.parse_cert(cert_text)
pk   = helpers.parse_key(key_text)

# create config
config = invoices.Config(cert, pk, 141, "1patro-vpravo")

# create factory using config
factory = invoices.Factory(config)

# build new invoice & send
invoice = factory.new("141-18543-05", 236.00, zakl_dan1=100.0, dan1=21.0)
response = invoice.send()
# note: if resending, you should set `eet.invoice.Hlavicka["prvni_zaslani"] = eet.types.boolean(False)`
#       or use scheduler ;-)

# now validate response and get fik
codes = response.codes()
if response:
    print("BKP: {0}\nFIK: {1}".format(codes.bkp, codes.fik))
else:
    print("BKP: {0}\nPKP: {1}".format(codes.bkp, codes.pkp))

Example of scheduler

from eet import invoices, helpers, remote

... # prepare invoice as before

# create instance of scheduler
scheduler = remote.Scheduler()

# same as before but now you can resend invoices
response = scheduler.process(invoice)

# call dispatch is reasonable time interval from your mainloop

import time
while True:
    scheduler.dispatch()

    time.sleep(60)
