1-Click SDD payment
1-Click payment (or payment by token) requires a signed recurring mandate.
With each payment, the Merchant transmits the UMR to be debited in his or her payment form.
The payment gateway retrieves the mandate information and displays it to the Buyer.
The Buyer confirms the bank details and receives a direct debit notification.
The date of funds transfer is calculated on the basis of the pre-notification delay and the capture delay.
It is transmitted in the response via the vads_presentation_date field.
