Quick Start

Get up and running with Access Control Client in just a few steps:

npm install @itwin/access-control-client

import { AccessControlClient } from "@itwin/access-control-client";

const client = new AccessControlClient();
const accessToken = "your-access-token-string";
const roles = await client.roles.getITwinRoles(accessToken, "itwin-id");
console.log(`Found ${roles.data!.length} roles`);

Installation

# Using npm
npm install @itwin/access-control-client

# Using yarn
yarn add @itwin/access-control-client

# Using pnpm
pnpm add @itwin/access-control-client

Basic Usage

Authentication

All API methods require an access token string. See the iTwin Platform documentation for authentication setup.

API Reference

Core Classes

• AccessControlClient - Main client for all access control operations
• IAccessControlClient - Interface defining the client API surface

Sub-Clients

The AccessControlClient exposes the following specialized sub-clients:

Access Management

• permissions - Query permissions across the platform and iTwins
• roles - Manage iTwin roles (CRUD operations)

Group Management

• groups - Manage iTwin groups (CRUD operations)
• groupMembers - Manage members within groups
• groupMemberInvitations - Handle group member invitation lifecycle

User Management

• userMembers - Manage individual user members of iTwins
• ownerMembers - Manage iTwin owner memberships
• memberInvitations - Handle member invitation lifecycle

Advanced Operations

• itwinJobs - Bulk operations for member management
• itwinShares - Manage iTwin sharing and access tokens

Key Features

• ✅ Complete CRUD operations for roles, groups, and members
• ✅ Bulk operations via iTwin Jobs
• ✅ Invitation management for users and groups
• ✅ Sharing capabilities for controlled iTwin access
• ✅ Type-safe API with full TypeScript support

Quick Reference

import { AccessControlClient } from "@itwin/access-control-client";
import type {
  BentleyAPIResponse,
  Role,
  MultipleUserMembersResponse
} from "@itwin/access-control-client";

const client = new AccessControlClient();
const accessToken = "your-access-token-string";
const iTwinId = "your-itwin-id";

// Get roles
const roles = await client.roles.getITwinRoles(accessToken, iTwinId);

// Create a role
const newRole = await client.roles.createITwinRole(accessToken, iTwinId, {
  displayName: "Project Manager",
  description: "Role for project management"
});

// Query user members
const members = await client.userMembers.queryITwinUserMembers(
  accessToken,
  iTwinId,
  { top: 10 }
);

// Add user members
const addedMembers = await client.userMembers.addITwinUserMembers(
  accessToken,
  iTwinId,
  [{
    email: "user@example.com",
    roleIds: ["role-id"]
  }],
  "Welcome message"
);
