At the moment you can only offer Subscription Payments with Card Payments. To offer subscriptions through Nordea Connect, you will need to have a Card Acquirer agreement with subscriptions enabled.
In order to create a Subscription, log in to Nordea Connect Merchant Portal and choose "Billing plans" from the menu on the left side of your screen. From there you may add a new Subscription by choosing "Create a new plan" or manage the existing Subscription options. After you have created the Billing plans you want to offer to your customers, you can activate them in "Payment forms" or by creating"Payment templates".
