TrustPay payments integration library.

Project description

TrustPay payment solution integration helpers.


$ pip install trustpaylib


Form approach

First merge payment request with environment variables, validate it and sign. trustpaylib.TrustPay.finalize_request returns prepared payment request. As form action use trustpay_client.environment.api_url.

>>> pay_request = trustpay_client.finalize_request(pay_request)
>>> trustpay_client.initial_data(pay_request)
{'AID': '9876543210', 'REF': u'1234567890', 'AMT': u'123.45', 'SIG': 'DF174E635DABBFF7897A82822521DD739AE8CC2F83D65F6448DD2FF991481EA3', 'CUR': u'EUR'}
>>> trustpay_client.environment.api_url

Redirects handling

There’s not much you can (or should) do with redirect.


Official TrustPay documentation: DO NOT PERFORM ANY ACTION ON THIS REDIRECT. Data is not signed and therefore cannot beconsidered as a verified payment result, such as the signed results sent to Notification URL or NotificationEmail.

But at least you can check the result code.

>>> # data received as get params to redirect
... redirect_data = {"REF": "1234567890", "RES": 3, "PID": "1212321"}
>>> redirect = trustpaylib.build_redirect(**redirect_data)
>>> trustpay_client.get_result_desc_from_redirect(redirect).short
>>> trustpay_client.get_result_desc_from_redirect(redirect).long
'Payment was successfully authorized. Another notification (with result code 0 - success) will be sent when TrustPay receives and processes payment from 3rd party.'

Notifications handling

For received notification, first check signature.

>>> notification_data = {
...     "AID": "1234567890",
...     "TYP": "CRDT",
...     "AMT": "123.45",
...     "CUR": "EUR",
...     "REF": "9876543210",
...     "RES": "0",
...     "TID": "11111",
...     "OID": "1122334455",
...     "TSS": "Y",
...     "SIG": (
...         "97C92D7A0C0AD99CE5DE55C3597D5ADA"
...         "0D423991E2D01938BC0F684244814A37"
...     ),
... }
>>> notification = trustpaylib.build_notification(**notification_data)
>>> assert trustpay_client.check_notification_signature(notification)

Then check result code.

>>> trustpay_client.get_result_desc_from_notification(notification).short
>>> trustpay_client.get_result_desc_from_notification(notification).long
'Payment was successfully processed.'
