# List ACLs

`GET /kafka/v3/clusters/{cluster_id}/acls`

[![Generally Available](https://img.shields.io/badge/Lifecycle%20Stage-Generally%20Available-%2345c6e8)](#section/Versioning/API-Lifecycle-Policy)
- When calling `/acls` without the `principal` parameter, service
  accounts are returned in numeric ID format (e.g., `User:12345`).
- To retrieve service accounts in the `sa-xxx` format, use
  `/acls?principal=UserV2:*`.
- The `principal` parameter supports both legacy `User:` format and
  new `UserV2:` format for service accounts.
Return a list of ACLs that match the search criteria.
