Subscriptions

With the subscription API you can perform recurring payments.
With a subscription comes a Mandate, which is what
actually allows the merchant to make multiple payments. When creating a new subscription a mandate is automatically
created aswell. Normally it's not nessecary for a subscription to have more than one mandate, but it is possible if your
use-case requires it.

Mandates

A mandate gives the merchant the permission to create payments on behalf of the customer.
