django-oscar-worldpay 1.1

Current status

We believe this product is usable in production, but as always, it is released as-is without warranty. If you find any bugs please submit either a bug report or a pull request.

Security

This package supports the so-called ‘MD5 Encryption’ security of Worldpay, with configurable fields. It also implement the DNS based checking of response callbacks.

It uses C_Parameters internally for passing cart information back, this uses a SHA-based HMAC for verification.

This package doesn’t yet support the callbackPW parameter, patches to add this would be very welcome.

Configuration

The following parameters should be set:

• WORLDPAY_INSTANCE_ID

  A string containing your instance ID, such as ‘12345’

• WORLDPAY_TEST_MODE

  A boolean to determine test mode

• WORLDPAY_MD5_SECRET

  The string entered in the MD5 field of WorldPay’s console, or None

• WORLDPAY_SIGNATURE_FIELDS

  A tuple of field names, such as (‘instId’, ‘cartId’, ‘amount’, ‘currency’), to use with the MD5 Secret

• WORLDPAY_REMOTE_ADDRESS_HEADER

  A string pointing to the key in Request.META that contains the IP of the request’s origin. Usually either REMOTE_ADDR or HTTP_X_FORWARDED_FOR.

Gotchas

Worldpay’s recommended authentication of requests is based on multiple DNS lookups. Please be sure you have a working and reliable DNS setup before using this package. Patches to make this lookup optional and to add the CallbackPW alternative would be welcome.

You also need the dynamic callback response parameter to be enabled. Currently there are two callbacks, a fail and a success callback. If these two were integrated this requirement could be dropped.

License

The package is released under the New BSD license.
