Wirecard

A Python wrapper for the Wirecard REST API. Only supports credit card payments with 3D secure enrolment.

All examples below use Wirecard test data. You can find them in the links below:

• API Credentials
• 3D Credit Card

Setting up environment variables

export WIRECARD_USERNAME='70000-APILUHN-CARD'
export WIRECARD_PASSWORD='8mhwavKVb91T'
export WIRECARD_MERCHANT_ACCOUNT_ID='33f6d473-3036-4ca5-acb5-8c64dac862d1'
export WIRECARD_API_URL='https://api-test.wirecard.com/engine/rest/payments'
export WIRECARD_ORIGIN_IP='127.0.0.1'

Using it

from wirecard import AccountHolder, Card, RequestedAmount, Wirecard


card = Card(
    account_number='4012000300001003',
    expiration_month='01',
    expiration_year='2023',
    security_code='003',
    _type='visa',
)
account_holder = AccountHolder(
    first_name='John',
    last_name='Doe',
)
requested_amount = RequestedAmount(
    amount='10.99',
    currency='ZAR',
)

w = Wirecard()

result = w.check_3d_enrollment(card, account_holder, requested_amount)

# If everything is fine, you should redirect the user to the ACS page
# https://document-center.wirecard.com/display/PTD/Payment+Features#PaymentFeatures-ACSHTTPSRedirect

# Here's a Django View Example
transaction_id = result.get('payment').get('transaction-id')
acs_url = result.get('payment').get('three-d').get('acs-url')
pareq = result.get('payment').get('three-d').get('pareq')

context = {
    'acs_url': acs_url,
    'pareq': pareq,
    'term_url': 'https://your_callback_url',
    'md': f'{"transaction_id": {transaction_id}, "cvv": {card.security_code}}',
}

return render(
    request,
    'acs_template.html',
    context,
)

# The bank successfully calls your callback
# Here's a Django View Example
pares = request.POST.get('PaRes')
md = json.loads(request.POST.get('MD', 'null'))

parent_transaction_id = md['transaction_id']
cvv = md['cvv']

w = Wirecard()
result = w.authorize_and_capture_payment(pares, parent_transaction_id, cvv)

Instead of using environment variables, you can initialize the Wirecard with the necessary information:

w = Wirecard(
    username='70000-APILUHN-CARD',
    password='8mhwavKVb91T',
    merchant_account_id='33f6d473-3036-4ca5-acb5-8c64dac862d1',
    url='https://api-test.wirecard.com/engine/rest/payments',
)

Exceptions

• WirecardFailedInit: raised when the initialization of Wirecard fails
• WirecardInvalidCard: raised when an invalid card is given to Card
• WirecardInvalidRequestedAmount: raised when an invalid card is given to RequestedAmount
• WirecardFailedTransaction: raised when any communication with the Wirecard platform fails
• WirecardInvalidResponse: Raised when Wirecard fails to return JSON
