Motivation and Context

Solves the issue #4397

How did you test it?

I have tested the Multisafe payment connector for Giropay and iDeal methods in Postman suit. You can find my fork of Postman's collection below. In Payments - Create iDeal Payment and Payments - Create Giropay Direct in Quick Start are the requests for the payments.

iDeal

By requesting the iDeal payment method with "Ing" bank name, a redirection link can be found, redirecting to the test portal of Multisafepay, where we can see the bank name we selected. Also, passing bank names not supported by iDeal raises an Error.

Not Passing the bank name in the payment_method_data returns an error, too.

Giropay

Giropay doesn't support the direct method, so it is not compulsory to enter bank_name into the payment_method_data. After a successful request to Multisafepay, We will get a redirection link to the Mutisafepay payment's page.
