Use this to review billable metric setup before associating it with products. Returns the metric's `name`, `event_type_filter`, `property_filters`, `aggregation_type`, `aggregation_key`, `group_keys`, `custom fields`, and `SQL query` (if it's a SQL billable metric). Important: - Archived billable metrics will include an `archived_at` timestamp; they no longer process new usage events but remain accessible for historical reference. ## OpenAPI ````yaml /openapi.json get /v1/billable-metrics/{billable_metric_id} openapi: 3.0.1 info: title: Metronome version: 1.0.0 servers: - url: https://api.metronome.com description: Production server security: - bearerAuth: [] tags: - name: Customers description: >- [Customers](https://docs.metronome.com/provisioning/create-customers/) in Metronome represent your users for all billing and reporting.
