# Add RBAC Group Member

`BetaRbacGroupMember beta().organization().rbacGroups().members().add(params, requestOptions = RequestOptions.none())`

**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.

## Parameters

  - `Optional<String> rbacGroupId` (path parameter)

    ID of the RBAC Group.

  - `String userId`

    ID of the User.

## Returns

- `class BetaRbacGroupMember`

  - `JsonValue type = "rbac_group_member"`

    Object type.

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

  - `LocalDateTime createdAt`

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

    format: date-time

  - `String email`

    Email of the User.

  - `String rbacGroupId`

    ID of the RBAC Group.

  - `String userId`

    ID of the User.

            .rbacGroupId("rbac_group_id")
            .userId("user_01WCz1FkmYMm4gnmykNKUu3Q")
