How did you test it?

Used "Payments - Create" request in the Postman collection to test the API's

Giropay

Giropay only supports redirect payment type. Hence, the bank name need not be provided.

A redirection link will be found in the response which redirects to the Multisafepay test platform, where the status of the payment can be seen

Ideal

Ideal supports both direct and redirect payment types.

Ideal - Direct

For proceesing a payment through direct type, bank name supported by ideal must be provided.

A redirection link will be found in the response which redirects to the Multisafepay test platform, where the status of the payment can be seen along with the bank name and it's logo.

Ideal - Redirect

For redirect type, the bank name should not be provided.

The redirect url redirects to the Multisafepay test platform where a bank can be chosen.

Upon choosing the bank name, it redirects to the Multisafepay test platform page with the selected bank name and payment status.
