Django payments payu

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:

class payments_payu.provider.PayuProvider(client_secret, second_key, pos_id[, sandbox=False, endpoint="https://secure.payu.com/", recurring_payments=False, express_payments=False, widget_branding=False])

This backend implements payments using PayU.com.

Set up the payment provider:

Example:

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

Here are valid parameters for the provider:

client_secret:PayU OAuth protocol client secret pos_id:PayU POS ID second_key:PayU second key (MD5) shop_name:Name of the shop send to the API sandbox:if True, set the endpoint to sandbox endpoint:endpoint URL, if not set, the will be automatically set based on sandbox settings recurring_payments:  enable recurring payments, only valid with express_payments=True, see bellow for additional setup, that is needed express_payments:  use PayU express form widget_branding:  tell express form to show PayU branding store_card:(default: False) whether PayU should store the card

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,
        'noreply@test.com',
        [user.email],
        fail_silently=False,
    )
