Interface SubscriptionItemDeleteParams

Delete all usage for the given subscription item. Allowed only when the current plan's usage_type is metered.

Determines how to handle prorations when the billing cycle changes (e.g., when switching plans, resetting billing_cycle_anchor=now, or starting a trial), or if an item's quantity changes. The default value is create_prorations.

If set, the proration will be calculated as though the subscription was updated at the given time. This can be used to apply the same proration that was previewed with the upcoming invoice endpoint.
