## Create list items

**post** `/accounts/{account_id}/rules/lists/{list_id}/items`

Appends new items to the list.

This operation is asynchronous. To get current the operation status, invoke the `Get bulk operation status` endpoint with the returned `operation_id`.

There is a limit of 1 pending bulk operation per account. If an outstanding bulk operation is in progress, the request will be rejected.
