Usage

Prepare payment data

In your checkout view prepare TrustPay payment data:

trustpay_payment_data = {
    # required
    'amount': 123.45,
    'currency': trustpay.CURRENCY_EUR,
    'reference': u'ORDER-123',  # Don't put # sign in reference. It will be returned back as GET parameter.

    # not required
    'language': get_language_code(request),
    'country': trustpay.COUNTRY_SLOVAK_REPUBLIC,
    'description': u'This is Trustpay test payment',
    'customer_email': u'[email protected]'
}

and create TrustPay form with hidden fields and 'Pay' submit button:

trustpayform = TrustPayClient(is_test=settings.DEBUG).get_form(**trustpay_payment_data)

Render payment form

Put TrustPay form to your template:

{% include 'trustpay/helpers/form.html' with form=trustpayform submit_label='Pay with TrustPay' %}

Handle return views

By default, SuccessReturnView, ErrorReturnView, CancelReturnView simply print request data and error message if any. You should override templates trustpay/success_return.html, trustpay/error_return.html and trustpay/cancel_return.html or define your own return views. If you decide to use your own return views, don't forget to set TRUSTPAY_SUCCESS_RETURN_URL, TRUSTPAY_ERROR_RETURN_URL and TRUSTPAY_CANCEL_RETURN_URL settings.

Handle notification view

trustpay.views.NotificationView stores every notification from TrustPay service to database. You shouldn't have set BasicAuth or any other authentication on this view (reverse('trustpay_notification')), because TrustPay won't be able to access it.

I recommend you to create a cron job which will handle each safe notification (with flag is_safe - it means the payment request from merchant was signed and return signature is correct).

Helpers

get_result_message(result_code)
returns result message by result code
get_language_code(request)
returns TrustPay supported language code by request

Constants

trustpay package contains all TrustPay supported currencies and countries.
