Python implementation of Transbank's Webpay protocol.

Installation

pip install tbk

Usage

Set environment variable for Commerce and initialize.

os.environ['TBK_COMMERCE_ID'] = "597026007976"
os.environ['TBK_COMMERCE_KEY'] = "-----BEGIN RSA PRIVATE KEY-----\nMIIEowIBAAKCAQEAn3HzPC1ZBzCO3edUCf/XJiwj3bzJpjjTi/zBO9O+DDzZCaMp...""

from tbk.webpay.commerce import Commerce

commerce = Commerce.create_commerce()
# for development purposes you can use
# commerce = Commerce(testing=True)

If you want to set the official webpay log (for certification issues):

from tbk.webpay.logging import configure_logger
from tbk.webpay.logging.official import WebpayOfficialHandler

configure_logger(WebpayOfficialHandler(LOG_BASE_PATH))

Create a new payment and redirect user.

from tbk.webpay.payment import Payment

payment = Payment(
    request_ip='127.0.0.1', # customer request ip
    commerce=commerce,
    success_url='http://localhost:8080/webpay/success/',
    confirmation_url='http://111.122.133.144:8080/webpay/confirmation/', # callback url with IP
    failure_url='http://localhost:8080/webpay/failure/',
    session_id='SOME_SESSION_VALUE',
    amount=123456, # could be int, str or Decimal
    order_id=1,
)
payment.redirect_url

Then to confirm payment, use an endpoint with:

from tbk.webpay.confirmation import Confirmation

def confirm_payment(request):
    confirmation = Confirmation(
        commerce=commerce,
        request_ip=request.ip_address,
        data=request.POST
    )

    # validate_confirmation validate if order_id and amount are valid.
    if confirmation.is_success() and validate_confirmation(confirmation.order_id, confirmation.amount):
        return HttpResponse(commerce.acknowledge)

    return HttpResponse(commerce.reject)
