PaymentExpress PxPay Gateway for Django

Installation:

pip install django-pxpay or easy_install django-pxpay

Usage:

You'll need to add a few items in your settings.py: PXPAY_USERID, PXPAY_KEY and, optionally, PXPAY_CURRENCY.

from django.shortcuts import redirect, render_to_response
from django.template.context import RequestContext
from django.http import Http404
from pxpay.gateway import Gateway


def payment(request, amount):
    # Create a transaction.
    txn = Gateway().transaction(
        TxnType='Purchase',
        AmountInput='%.2f' % amount,
        CurrencyInput='AUD',  # Alternatively, can be provided in settings.py
        MerchantReference='Some reference')

    # Send payment request.
    response = Gateway().process_transaction(
        txn,
        UrlFail=request.build_absolute_uri(reverse('process_payment')),
        UrlSuccess=request.build_absolute_uri(reverse('process_payment')))

    # Redirect to PaymentExpress hosted payment page.
    if response.is_valid:
        return redirect(response.get_data['URI'])

    # Show error.
    else:
        return payment_result(request, False, 'Invalid Transaction Request')


def process_payment(request):
    # Proper PaymentExpress request would always have these.
    if 'result' in request.GET and 'userid' in request.GET:

        # Process PaymentExpress response.
        process_response = Gateway().process_response(
            Response=request.GET['result'])

        # Show payment result.
        return payment_result(
            request,
            bool(int(process_response.get_data['Success'])),
            process_response.get_data['ResponseText'])

    # Rise 404 if no required arguments were passed.
    raise Http404


def payment_result(request, success, msg):
    return render_to_response(
        'payment.html',
        {'success': success, 'msg': msg},
        context_instance=RequestContext(request))
