# Group clusters API (certificate-based) (DEPRECATED) **(FREE)**
> - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/30213) in GitLab 12.1.
> - [Deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5.
WARNING:
This feature was [deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5.
Similarly to [project-level](../user/project/clusters/index.md) and
[instance-level](../user/instance/clusters/index.md) Kubernetes clusters,
group-level Kubernetes clusters allow you to connect a Kubernetes cluster to
your group, enabling you to use the same cluster across multiple projects.
Users need at least the Maintainer role for the group to use these endpoints.
## List group clusters
Returns a list of group clusters.
```plaintext
GET /groups/:id/clusters
```
Parameters:
| Attribute | Type | Required | Description |
| --------- | -------------- | -------- | ----------------------------------------------------------------------------- |
| `id` | integer/string | yes | The ID or [URL-encoded path of the group](index.md#namespaced-path-encoding) |
Example request:
```shell
curl --header "Private-Token: <your_access_token>" "https://gitlab.example.com/api/v4/groups/26/clusters"
```
Example response:
```json
[
