  /**
   * Creating the backfill enables adding or replacing past events, even those that
   * are older than the ingestion grace period. Performing a backfill in Orb involves
   * 3 steps:
   *
   * 1. Create the backfill, specifying its parameters.
   * 2. [Ingest](ingest) usage events, referencing the backfill (query parameter
   *    `backfill_id`).
   * 3. [Close](close-backfill) the backfill, propagating the update in past usage
   *    throughout Orb.
   *
   * Changes from a backfill are not reflected until the backfill is closed, so you
   * won’t need to worry about your customers seeing partially updated usage data.
   * Backfills are also reversible, so you’ll be able to revert a backfill if you’ve
   * made a mistake.
   *
   * This endpoint will return a backfill object, which contains an `id`. That `id`
   * can then be used as the `backfill_id` query parameter to the event ingestion
   * endpoint to associate ingested events with this backfill. The effects (e.g.
   * updated usage graphs) of this backfill will not take place until the backfill is
   * closed.
   *
   * If the `replace_existing_events` is `true`, existing events in the backfill's
   * timeframe will be replaced with the newly ingested events associated with the
   * backfill. If `false`, newly ingested events will be added to the existing
   * events.
   *
   * If a `customer_id` or `external_customer_id` is specified, the backfill will
   * only affect events for that customer. If neither is specified, the backfill will
   * affect all customers.
   *
   * When `replace_existing_events` is `true`, this indicates that existing events in
   * the timeframe should no longer be counted towards invoiced usage. In this
   * scenario, the parameter `deprecation_filter` can be optionally added which
   * enables filtering using
   * [computed properties](/extensibility/advanced-metrics#computed-properties). The
   * expressiveness of computed properties allows you to deprecate existing events
   * based on both a period of time and specific property values.
   *
   * You may not have multiple backfills in a pending or pending_revert state with
   * overlapping timeframes.
