# Container tags

> Multi-tenant containers — settings, merge, and delete.

`containerTag` is the primary multi-tenant key (user id, workspace id, etc.). These endpoints manage settings and lifecycle for a tag.

| Endpoint                                   | Use when                        |
| ------------------------------------------ | ------------------------------- |
| `GET /v3/container-tags/{containerTag}`    | Read tag settings               |
| `PATCH /v3/container-tags/{containerTag}`  | Update tag settings             |
| `DELETE /v3/container-tags/{containerTag}` | Delete a container and its data |
| `POST /v3/container-tags/merge`            | Merge one tag into another      |
| `GET /v3/container-tags/merge/{mergeId}`   | Poll merge status               |
