# Add RBAC Group Member

`$ ant beta:organization:rbac-groups:members add`

**POST** `/v1/organizations/rbac_groups/{rbac_group_id}/members`

Add a User to an RBAC Group. Membership of groups provisioned by an identity provider (source type `"scim"`) cannot be modified via the API while an organization in the tenant uses SCIM provisioning.

The RBAC Groups API is available to Claude Enterprise organizations only.

  ID of the RBAC Group.

- `--user-id: string`

  ID of the User.

## Returns

- `beta_rbac_group_member: object`

  - `type: "rbac_group_member"`

    Object type.

    For RBAC Group Members, this is always `"rbac_group_member"`.

  - `created_at: string`

    RFC 3339 timestamp of when the User was added to the RBAC Group.

    format: date-time

  - `email: string`

    Email of the User.

  - `rbac_group_id: string`

    ID of the RBAC Group.

  - `user_id: string`

    ID of the User.
