# List the token owner's list folders of one kind

> The token owner's folders of one kind: `contactList` and `companyList` folders organise lists (the `folderId` on `GET /business/lists` rows and `PATCH /business/lists/{listId}`), `campaign` folders organise campaigns, and `agent` folders organise agents. Not paginated — every folder of the kind is returned.

Errors:
- `422` `VALIDATION_FAILED` — type missing or outside contactList|companyList|campaign|agent.
- `429` `RATE_LIMITED` — The lists rate bucket is exhausted.
- `400` `INVALID_REQUEST` — agent/campaign kinds only: the owning service rejected the request (its own code is relayed when it sends one).

Requires one of the following token scopes: lists.
