# Add RBAC Group Member

`$client->beta->organization->rbacGroups->members->add(string rbacGroupID, string userID): BetaRBACGroupMember`

**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

- `rbacGroupID: string` (path parameter)

  ID of the RBAC Group.

- `userID: string`

  ID of the User.

## Returns

- `class BetaRBACGroupMember`

  - `"rbac_group_member" type`

    Object type.

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

  - `\Datetime createdAt`

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

  - `string email`

    Email of the User.

  - `string rbacGroupID`

    ID of the RBAC Group.

  - `string userID`

    ID of the User.
