# Create a list

`POST /lists`

Upload a list of creator handles + emails. Two paths: JSON body OR multipart CSV (file field name `file`, columns `creator_name` required + `email` optional). Returned `list_id` is what callers pass to automations as `lists_selected`.

## Headers

- `Idempotency-Key` string, nullable
- `X-Dry-Run` string, nullable

## Request body

  - `description` string, nullable
  - `creator_handles` string[] — TikTok handles, with or without leading '@'. Deduplicated case-insensitively at insert time.
