Which global instant notifications do I enable at 2checkout.com?

On the 2checkout option page /wp-admin/admin.php?page=membershipgateways&action=edit&gateway=twocheckout, it says: In order for recurring payments to log properly you must enable your global instant notifications url pointing to http://url.com/paymentreturn/twocheckout

When I go to https://www.2checkout.com/va/notifications/, do I want to enable just a single notification (like "Recurring Installment Success") or do I set this URL in the "Global URL" area -- for all the areas?
