PayU payments provider for django-payments

NOTE: This project is still in development, so use with extreme caution.

PayU payments provider for django-payments. Uses the new PayU REST API. Supports normal, express and recurring payments.

Documentation

The full documentation is at https://django-payments-payu.readthedocs.io.

Quickstart

Install django-payments and set up PayU payment provider backend according to django-payments documentation:

This backend implements payments using PayPal.com.

param client_secret:

PayU OAuth protocol client secret

param pos_id:

PayU POS ID

param second_key:

PayU second key (MD5)

param sandbox:

if True, set the endpoint to sandbox

param endpoint:

endpoint URL, if not set, the will be automatically set based on sandbox settings

param recurring_payments:

enable recurring payments, only valid with express_payments=True, see bellow for additional setup, that is needed

param express_payments:

use PayU express form

param widget_branding:

tell express form to show PayU branding

param store_card:

(default: False) whether PayU should store the card

Example:

# use sandbox
PAYMENT_VARIANTS = {
    'payu': ('payments_payu.provider.PayuProvider', {
        'pos_id': '123456',
        'second_key': 'iseedeadpeople',
        'client_secret': 'peopleiseedead',
        'sandbox': True,
        'capture': False,
    }),
}

Additional settings:

PayU requires users first name, last name and email. Override ether get_user or get_user_email, get_user_first_name and get_user_last_name methods from BasePayment.

NOTE: notifications about the payment status from PayU are requested to be sent to django-payments process_payment url. The request from PayU can fail for several reasons (i.e. it can be blocked by proxy). Use “Show reports” page in PayU administration to get more information about the requests.

Recurring payments:

If recurring payments are enabled, the PayU card token needs to be stored in your application for usage in next payments. The next payments can be either initiated by user through (user will be prompted only for payment confirmation by the express form) or by server. To enable recurring payments, you will need to set additional things:

NOTE: Recurring payments are not enabled by default even in Sandbox, you sould consult their helpdesk to enable this.

• In order to make payments recurring, the card token needs to be stored for the Payment’s user (not just the payment itself). Implement the Payment.set_renew_token() and Payment.get_renew_token().

• Implement Payment.get_payment_url().

• For the server initiated recurring payments you will need to create the new payment and then call payment.auto_complete_recurring().

  • The method returns either string ‘success’ or url where the user can provide his CVV2 or 3D secure information.

  • The 'success' string means, that the payment is waiting for notification from PayU, but no further user action is required.

Example of triggering recurring payment:

payment = Payment.objects.create(...)
redirect_url = payment.auto_complete_recurring()
if redirect_url != 'success':
    send_mail(
        'Recurring payment - action required',
        'Please renew your CVV2/3DS at %s' % redirect_url,
        '[e-mail]',
        [user.email],
        fail_silently=False,
    )
