Python GoPay API v2.3

Developed for Fraggo.net s.r.o. <http://www.fraggo.net/>

Django app to integrate GoPay into your project.

I implemented just a part of the API:

paymentStatus
paymentMethodList
createPayment

Feel free to add other parts!

Instalation

pip install https://github.com/creckx/gopay4django/zipball/master

Configuration

Add gopay into installed_apps and set these parameters:

GOPAY_DOMAIN = "http://<your domain>"
GOPAY_GOID = <your go id> # should be integer
GOPAY_FAILED_URL = <success url>
GOPAY_SUCCESS_URL = <failed url>
GOPAY_SECRET_KEY = <your secret key>
GOPAY_TEST_GW = <True or False>
GOPAY_LANG = <lang>
GOPAY_DEFAULT_PAYMENT_CHANNEL = "cz_cs_c"
GOPAY_PAYMENT_CHANNELS = ["cz_gp_u", "cz_gp_w", "cz_rb", "cz_vb", "cz_kb", "cz_cs_c", "cz_mb", "cz_fb", "cz_ge"]

Add this somewhere into your urls.

url(r'^gopay/', include('gopay4django.urls')),

If you don't know what codes you can use, try:

python manage.py payment_channels

When user comes back from GoPay to your site, this app handle the request and decide where will be user redirected. If all goes well, GOPAY_SUCCESS_URL will be used, otherwise GOPAY_FAILED_URL. There is also parametr payment_uuid to get payment data from Payment model.

Usage

gopay = GoPay()
url = gopay.create_payment(
    productName = "Jméno produktu",
    totalPrice = 1000,
    currency = "CZK",
    firstName = "Adam",
    lastName = "Štrauch",
    city = "Hradec Králové",
    street = "Ve Stromovce 123",
    postalCode = "50011",
    countryCode = "CZE",
    email = "info@example.com",
    phoneNumber=123456789,
    p1="some data",
    name="Some name, anything what can help you identify payment in administration"
)

Method create_payment() returns URL to redirect to GoPay payment gateway. After everything is done on gateway, user comes back to GOPAY_FAILED_URL or GOPAY_SUCCESS_URL.

Signal

GoPay sends notifications if something changes (for ex. payment is paid). When it happens, it save new payment status to database, returns 200 to GoPay gateway and sends signal payment_changed which you can catch and do something with it. Here is some example:

from gopay4django.signals import payment_changed

@receiver(payment_changed)
def payment_changed_callback(sender, **kwargs):
    payment = kwargs.get("payment")
    print "Payment %s changed status to %s" % (payment.uuid, payment.state)

Payment object

Payment model is ordinary model, but has two jsons fields, which you can access as dict.

Payment.payment_command
Payment.payment_status

For example:

payment = Payment.objects.all()[0]
payment.payment_status.get("sessionState") # returns state of payment
payment.payment_status.get("p1") # returns optinal paramete p1 (integration manual)
payment.payment_status.get("p2") # returns optinal paramete p2 (integration manual)
