Change subscriptions

A subscription represents a customer's entitlement to a product and determines their access to that product, as well as their payment schedule. Subscriptions are created when the customer places an order. Once you have a created a subscription, you may make changes to your subscription, depending on what options are available. You may be able to upgrade or downgrade the options on the current edition, or move to a different edition.

A subscription can be changed through the UI by selecting the "Update Edition" tab on the Manage->Account->Applications page for the given application. through an AppDirect-powered marketplace.

Once you have a created company, a user, a payment instrument for that user,  and a subscription on behalf of that user, you may manage the subscription.  This includes changing a subscription. AppDirect supports an OAuth-authenticated REST interface that allows API users to read, create, edit, and delete marketplace records that describe a subscription. These functions are all part of the Billing API, which is invokable through standard HTTP methods (GET, POST, PUT, and DELETE) using standard REST conventions. All calls to the Billing API occur under its endpoint URL, https://www.appdirect.com/api/billing/v1.
