The Python FinTech package (SEPA, EBICS & more)

Project description

This package contains all the functionality that is required to work with EBICS, SEPA and other financial technologies. The usage has been realised as simple as possible but also as flexible as necessary.

Features

  • Support of EBICS versions 2.4, 2.5 and 3.0

  • Support of EBICS websockets

  • Obtain bank account statements (incl. CAMT and MT940 parser)

  • Create and submit SEPA credit transfers (pain.001)

  • Create and submit SEPA direct debits CORE/B2B (pain.008)

  • Mostly full SEPA support (including special schemes for CH and IT)

  • Automatic calculation of the lead time based on holidays and cut-off times

  • Integrated mandate manager (beta)

  • Plausibility check of IBAN and BIC

  • Validation of payment orders against the SEPA Clearing Directory of the German Central Bank

  • Bankcode/Account to IBAN converter according to the rules of the German Central Bank

  • Currency converter

  • DATEV converter (CSV and KNE)

The FinTech package provides you the possibility to manage all of your everyday commercial banking activities such as credit transfers, direct debits or the retrieval of bank account statements in a flexible and secure manner.

All modules can be used free of charge. Only the unlicensed version of the EBICS module has few restrictions. The upload of SEPA documents is limited to a maximum of five transactions and bank account statements can not be retrieved for the last three days.

Examples

Simple SEPA Credit Transfer (pain.001)

import fintech
fintech.register()
from fintech.sepa import Account, SEPACreditTransfer

# Create the debtor account from an IBAN
debtor = Account('DE89370400440532013000', 'Max Mustermann')
# Create the creditor account from a tuple (IBAN, BIC)
creditor = Account(('AT611904300234573201', 'BKAUATWW'), 'Maria Musterfrau')
# Create a SEPACreditTransfer instance
sct = SEPACreditTransfer(debtor)
# Add the transaction
tx = sct.add_transaction(creditor, 10.00, 'Purpose')
# Render the SEPA document
print(sct.render())

Simple SEPA Direct Debit (pain.008)

import fintech
fintech.register()
from fintech.sepa import Account, SEPADirectDebit

# Create the creditor account from a tuple (ACCOUNT, BANKCODE)
creditor = Account(('532013000', '37040044'), 'Max Mustermann')
# Assign the creditor id
creditor.set_originator_id('DE98ZZZ09999999999')
# Create the debtor account from a tuple (IBAN, BIC)
debtor = Account(('AT611904300234573201', 'BKAUATWW'), 'Maria Musterfrau')
# For a SEPA direct debit a valid mandate is required
debtor.set_mandate(mref='M00123456', signed='2014-02-01', recurrent=True)
# Create a SEPADirectDebit instance of type CORE
sdd = SEPADirectDebit(creditor, 'CORE')
# Add the transaction
tx = sdd.add_transaction(debtor, 10.00, 'Purpose')
# Render the SEPA document
print(sdd.render())

EBICS

import fintech
fintech.register()
from fintech.ebics import EbicsKeyRing, EbicsBank, EbicsUser, EbicsClient

keyring = EbicsKeyRing(keys='~/mykeys', passphrase='mysecret')
bank = EbicsBank(keyring=keyring, hostid='MYBANK', url='https://www.mybank.de/ebics')
user = EbicsUser(keyring=keyring, partnerid='CUSTOMER123', userid='USER1')
# Create new keys for this user
user.create_keys(keyversion='A006', bitlength=2048)

client = EbicsClient(bank, user)
# Send the public electronic signature key to the bank.
client.INI()
# Send the public authentication and encryption keys to the bank.
client.HIA()

# Create an INI-letter which must be printed and sent to the bank.
user.create_ini_letter(bankname='MyBank AG', path='~/ini_letter.pdf')

# After the account has been activated the public bank keys
# must be downloaded and checked for consistency.
print(client.HPB())

# Finally the bank keys must be activated.
bank.activate_keys()

# Download CAMT53 bank account statements
data = client.C53(
    start='2019-02-01',
    end='2019-02-07',
    )
client.confirm_download()
