# Group and project members API

## Valid access levels

The access levels are defined in the `Gitlab::Access` module. Currently, these levels are recognized:

- No access (`0`)
- Guest (`10`)
- Reporter (`20`)
- Developer (`30`)
- Maintainer (`40`)
- Owner (`50`) - Only valid to set for groups

CAUTION: **Caution:**
Due to [an issue](https://gitlab.com/gitlab-org/gitlab/-/issues/219299),
projects in personal namespaces will not show owner (`50`) permission
for owner.

## Limitations

The `group_saml_identity` attribute is only visible to a group owner for [SSO enabled groups](../user/group/saml_sso/index.md).

The `email` attribute is only visible to a group owner who manages the user through [Group Managed Accounts](../user/group/saml_sso/group_managed_accounts.md).

## List all members of a group or project

Gets a list of group or project members viewable by the authenticated user.
Returns only direct members and not inherited members through ancestors groups.

This function takes pagination parameters `page` and `per_page` to restrict the list of users.

```plaintext
GET /groups/:id/members
GET /projects/:id/members
```

| Attribute | Type | Required | Description |
| --------- | ---- | -------- | ----------- |
| `id`      | integer/string | yes | The ID or [URL-encoded path of the project or group](README.md#namespaced-path-encoding) owned by the authenticated user |
| `query`   | string | no     | A query string to search for members |
| `user_ids`   | array of integers | no     | Filter the results on the given user IDs |

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/groups/:id/members"
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/:id/members"
```

## List all members of a group or project including inherited members
