As mentioned in the topic, Call Basics, the calls in the Zuora API are like verbs (they perform actions), and the things they perform actions upon are the objects. In other words, the Zuora API objects, such as Account, support the calls, such as subscribe.
The objects provide essential information needed to create and maintain a subscription, such as the information needed to create an account, contact information for that account, methods of payment for that account, and, of course, information relating to the subscription for that account.
