# Close backfill

`POST /events/backfills/{backfill_id}/close`

Closing a backfill makes the updated usage visible in Orb. Upon closing a backfill, Orb will asynchronously reflect
the updated usage in invoice amounts and usage graphs. Once all of the updates are complete, the backfill's status
will transition to `reflected`.

## Path parameters

- `backfill_id` string, required
