The payment methods are to be built in the following order:

1. CreditCard
   • Authorize
   • Purchase
   • Capture
   • Refund
   • Void
   • Query Pseudo Card (PKN Info)
   • Recurring (repeat) transaction)
2. PayPal
   • Purchase
3. DirectDebit
   • Authorize with payment page
   • Authorize without payment page
   • Purchase with payment page
   • Purchase without payment page
   • Capture
   • Refund
   • Void
   • Query Pseudo Card (PKN Info)
4. Giropay
   • Authorize (not sure if this is available)
   • Purchase (initialise)
   • Check bankstatus
   • Giropay issuer bank query
   • Retrieve sender information
   • Bank selection widget (not a message, perhaps a helper)
5. Paydirekt
   • Authorize
   • Purchase
   • Capture
   • Refund
   • Void
6. iDEAL
   • Purchase
7. EPS

iDEAL and EPS are not used in Germany, so are taking a lower priority.

The PaymentPage payment type supports multiple payment types, selectable by the user.

• Get Transaction message (covers all payment types)

To select for these payment types, we either need multiple gateways - one per payment type - or an option at the top level to switch between them. The multiple gateway approach would involve an awful lot of classes to deal with, so I'm going to head down the option approach, and see how that goes.

Direct Debit comes in two related forms:

• With a payment page.
• Without a payment page.

I've not looked into it enough yet to tell whether we need to treat it as two payment types, or just one with some data/logic differences triggered by the parameters.

There are other services too, so be added to this list. They include listing banks and customers, and managing card tokens.
