How does it work?

        1. Call POST v2/moneyins/paybybank/transfer/init, to receive a redirect URL and the transaction Id. <br /><p></p>
        2. Redirect the end-user to your bank selection page, were they can select their bank from the displayed list. <br /><p></p><b>Note:</b> If you specify the bankId in the request body, the end-user will be directed to their bank. <br />
        For further information on how to obtain bankIds, see: /v2/moneyins/ paybybank/transfer/banks 
        3. Once the end-user selects their bank they are redirected to the bank webpage to enter their credentials.
        <p></p><b>Note:</b> If you have previously specified the bankId the end-user only needs to enter their bank credentials at this stage. <br /><p></p>
        4. After successfully entering their credentials, the end-user will go through Strong Customer Authentication (SCA) to confirm their identity (SCA examples include: face recognition or mobile Bank App software). Some bank ask to SCA before entering credentials.<br /><p></p>
        5. Once successfully authenticated the end-user only needs to verify and validate the amount, comments and so forth on the bank website.
        <p></p>
        6. After submitting the payment, the end-user will be redirected to:
         <ul><li>returnUrl in case of success</li><li>cancelUrl in case of cancellation</li><li>errorUrl in case of error.</li></ul>
        These 3 URLs must be publicly accessible for the end-user. It must also be accessible to our WebKit server to send requests to the end-user.
