You can delete a subscription in Chargebee using the Delete Subscription button on the right panel of the subscription details page. Or you can use the delete a subscription API for this. Find more details regarding this here.

Here's a screenshot.

Note: Chargebee's hierarchy is Customer > Subscription > Invoices > Transactions. If a delete action is carried out (irreversible), the downward data linked to the entity will also be deleted.

For example, deleting a subscription will cause all linked invoices and transactions to be deleted. Deleting a customer will delete all linked subscriptions and data linked to it.
