Initialization of the giropay payment

You send the transaction data and receive a link (redirect URL) as a reply. Afterwards, you send your customer a redirection to that URL. This may be done through an HTTP redirect header, an HTML page with a corresponding meta tag or Javascript. The actual payment processing takes place as the customer logs into his online banking platform and confirms the prefilled transfer form there by entering a TAN. The notification of your application about the payment outcome is done via a GET request sent by GiroCheckout to the URL specified in the urlNotify parameter.
