# List backfills

`GET /events/backfills`

This endpoint returns a list of all backfills in a list format.

The list of backfills is ordered starting from the most recently created backfill. The response also includes
[`pagination_metadata`](/api-reference/pagination), which lets the caller retrieve the next page of results if they
exist.

## Query parameters

- `limit` integer — The number of items to fetch. Defaults to 20.
- `cursor` string, nullable — Cursor for pagination. This can be populated by the `next_cursor` value returned from the initial request.
