Add Subscription Items

The Cleverbridge platform supports product recommendations for subscriptions. The use cases presented in the subsequent topics, show how to add a subscription item to an already active subscription.


If the add-on item is usage-based, then the client must track consumption and maintain the customer's unused balance.

If you want to offer a one-time product to a subscription customer, use the Process Cart API endpoint rather than subscription APIs. For more information, see Process Cart > Use Cases.
