# Long-running operations

Long-running requests answer `202 Accepted` with a `Location` header that points to
`/api/v1/operations/{id}` and an `Operation` object. Poll it until `status` is `succeeded` or `failed`. Operation types
are `storyboard.preview` and `film.comments_apply`; more may follow within v1.

The operation also reports its end in the event feed (`operation.completed`), so you can follow it there instead of
polling. See [Operations](/api/operations) for the object and the endpoint.
