Use this endpoint to retire billable metrics that are no longer used. After a billable metric is archived, that billable metric can no longer be used in any new Products to define how that product should be metered. If you archive a billable metric that is already associated with a Product, the Product will continue to function as usual, metering based on the definition of the archived billable metric.
Archived billable metrics will be returned on the getBillableMetric and listBillableMetrics endpoints with a populated archived_at field.
