Mollie API 1.5.2.0
- Added FailedDateTime property to the PaymentResponse class.
- Fixed documentation mistakes for the method and webhookurl properties of the paymentrequest class.
- Renamed the "Message" property of the RefundRequest class "Description", since this was changed recently.
- Added support for the "Refund" paymentmethod, since this is used by the settlement payment revenue's value.
