# Add RBAC Group Member

**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.

## Path parameters

- `rbac_group_id: string`

  ID of the RBAC Group.

## Headers

- `"anthropic-version": optional string`

  The version of the Claude API you want to use.

## Body parameters

- `user_id: string`

  ID of the User.

## Returns

- `RBACGroupMember object`

  - `type: "rbac_group_member"`

    Object type.

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

    default: 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.

curl https://api.anthropic.com/v1/organizations/rbac_groups/$RBAC_GROUP_ID/members \
    -H 'Content-Type: application/json' \
    -H 'anthropic-version: 2026-10-21' \
