Check the Subscriptions API reference here.
PPaaS packages comprise one or more number of services. If you wish to use any of our services, you will need to subscribe to the package which comprises the required service. Once the service is subscribed, you will be able to activate/deactivate them for your merchants as per their requirements. Any package can be subscribed or unsubscribed only at merchant administrator (MA) i.e., at an organization level.
