If the customer does not have an Everifin account, they can still save the account for future use in the Everifin payment gateway. In this case, after being redirected to PayGate, the customer must check the checkbox to save the selected account for future use in this browser. At the same time, the customer authorises the payment gateway to store this data for 90 or 180 days. During this period, the customer does not need to select the bank or insert the bank login details again. Confirmation of the payment will only take place via the second factor, reducing the time the customer has to interact with the bank to fill in the confirmation details.
Payment initiation
Payment should be initiated exactly the same way as default one-time anonymous payment. Please follow the documentation on Paygate Redirect Flow or https://documenter.getpostman.com/view/19017018/2s93kxbRWa#49488198-9737-4ad4-a863-44fb2356554b
