How to scope an OAuth client to specific divisions for multi-tenant BPO access

What You Will Build

• This tutorial demonstrates how to create an API client that authenticates with Genesys Cloud and restricts its data access to a specific organizational division, enabling secure multi-tenant operations for Business Process Outsourcing (BPO) providers.
• The implementation uses the Genesys Cloud PureCloud Platform Client V2 SDK and the underlying REST API endpoints for identity and division management.
• The primary programming language covered is Python 3.10+, with conceptual notes applicable to JavaScript and Java implementations.

Prerequisites

• OAuth Client Type: A Genesys Cloud OAuth client with Client Credentials grant type. The client must have the admin:division and admin:division:read scopes to manage division assignments, and the specific business scopes (e.g., analytics:conversation:read) to access data.
• API Version: Genesys Cloud API v2 (stable).
• Runtime: Python 3.10 or higher.
• Dependencies:
  • purecloudplatformclientv2>=12.0.0 (The official Genesys Cloud Python SDK).
  • requests>=2.28.0 (For low-level HTTP operations if needed for debugging).
  • pydantic>=2.0.0 (For data validation, optional but recommended).

Authentication Setup

To interact with divisions and enforce tenant isolation, you must first establish a valid OAuth 2.0 Bearer token. In a multi-tenant BPO scenario, the OAuth client typically represents a service account that has administrative rights across multiple divisions within a single Genesys Cloud organization, or potentially across organizations if using specific cross-org permissions (though divisions are the primary unit of isolation within an org).

The following code initializes the SDK client and retrieves an access token.

import os
import purecloudplatformclientv2
from purecloudplatformclientv2.rest import ApiException

def get_platform_client() -> purecloudplatformclientv2.PureCloudPlatformClientV2:
    """
    Initializes the Genesys Cloud Platform Client with Client Credentials.
    
    Returns:
        PureCloudPlatformClientV2: The configured client instance.
    """
    # Load credentials from environment variables to avoid hardcoding secrets
    client_id = os.getenv('GENESYS_CLIENT_ID')
    client_secret = os.getenv('GENESYS_CLIENT_SECRET')
    base_url = os.getenv('GENESYS_BASE_URL', 'https://api.mypurecloud.com')

    if not client_id or not client_secret:
        raise ValueError("GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET must be set in environment variables.")

    try:
        # Initialize the platform client
        client = purecloudplatformclientv2.PureCloudPlatformClientV2()
        
        # Configure the client for client credentials flow
        # This internally handles the token exchange with /api/v2/oauth/token
        client.set_client_credentials(client_id, client_secret)
        
        # Set the base URL for the API calls
        client.set_base_url(base_url)
        
        return client

    except ApiException as e:
        print(f"Failed to initialize client: {e}")
        raise

# Example usage
if __name__ == "__main__":
    try:
        client = get_platform_client()
        print("Platform client initialized successfully.")
    except Exception as e:
        print(f"Error: {e}")

Required Scope: admin:division (for creating/assigning users to divisions), admin:division:read (for listing divisions).

Token Caching: The PureCloud SDK automatically handles token caching and refresh. When set_client_credentials is called, the SDK stores the token in memory. Subsequent API calls will automatically attach the Authorization: Bearer <token> header. If the token expires, the SDK will automatically request a new one using the client credentials, provided the client secret is retained in memory.

Implementation

Step 1: Identify the Target Division

In a multi-tenant BPO setup, you must know the divisionId of the tenant you wish to isolate. Divisions are logical containers for users, queues, and data. Accessing data without specifying a division often results in returning data for the “Default” division or, if the user has access to multiple divisions, potentially ambiguous results depending on the API endpoint.

We will retrieve the list of divisions to identify the correct ID.

import purecloudplatformclientv2
from purecloudplatformclientv2.rest import ApiException

def find_division_by_name(client: purecloudplatformclientv2.PureCloudPlatformClientV2, division_name: str) -> str | None:
    """
    Searches for a division by its name and returns its ID.
    
    Args:
        client: The initialized PureCloud Platform Client.
        division_name: The exact name of the division to find.
        
    Returns:
        The division ID string if found, otherwise None.
    """
    try:
        # Create the API instance for Identity Management
        identity_api = purecloudplatformclientv2.IdentityManagementApi(client)
        
        # List all divisions the client has access to
        # Note: Pagination is handled automatically by the SDK if you use iterate_page or similar,
        # but for simplicity, we fetch the first page. In production, iterate all pages.
        response = identity_api.post_identity_divisions(
            body=purecloudplatformclientv2.PagedDivisionEntityListingRequest(
                page_size=100,
                page_number=1
            )
        )
        
        if not response.entities:
            print("No divisions found.")
            return None
            
        for division in response.entities:
            if division.name == division_name:
                print(f"Found division: {division.name} (ID: {division.id})")
                return division.id
                
        print(f"Division '{division_name}' not found.")
        return None

    except ApiException as e:
        if e.status == 401:
            print("Authentication error: Invalid or expired token.")
        elif e.status == 403:
            print("Forbidden: The OAuth client lacks the 'admin:division:read' scope.")
        else:
            print(f"API Error: {e.status} - {e.reason}")
        raise

Endpoint: POST /api/v2/identity/divisions
Scope: admin:division:read

Step 2: Create a User Scoped to the Division

To enforce strict isolation, you should create a dedicated service account (User) for the BPO tenant and assign it exclusively to the target division. This ensures that any API calls made by this user are implicitly filtered to that division.

import purecloudplatformclientv2
from purecloudplatformclientv2.rest import ApiException

def create_tenant_user(
    client: purecloudplatformclientv2.PureCloudPlatformClientV2,
    division_id: str,
    username: str,
    email: str,
    first_name: str,
    last_name: str
) -> str | None:
    """
    Creates a new user and assigns them to a specific division.
    
    Args:
        client: The initialized PureCloud Platform Client.
        division_id: The ID of the division to assign the user to.
        username: Unique username for the new user.
        email: Email address for the new user.
        first_name: First name of the user.
        last_name: Last name of the user.
        
    Returns:
        The ID of the newly created user, or None if failed.
    """
    try:
        user_management_api = purecloudplatformclientv2.UserManagementApi(client)
        
        # Construct the user body
        # The 'division' field is critical for scoping
        user_body = purecloudplatformclientv2.User(
            username=username,
            email=email,
            first_name=first_name,
            last_name=last_name,
            division=purecloudplatformclientv2.DivisionEntity(
                id=division_id,
                name="Tenant BPO Division" # Name is often optional if ID is present, but good for clarity
            ),
            # Assign a basic role that allows API access but restricts admin privileges
            # You must have a role ID that has 'api:access' and specific data scopes
            roles=[
                purecloudplatformclientv2.Role(
                    id="api_user", # Replace with actual Role ID for your org
                    name="API User"
                )
            ]
        )
        
        response = user_management_api.post_users(body=user_body)
        
        print(f"User created successfully. User ID: {response.id}")
        return response.id

    except ApiException as e:
        if e.status == 409:
            print("Conflict: User with this username already exists.")
        elif e.status == 403:
            print("Forbidden: The OAuth client lacks 'admin:user' or 'admin:division' scope.")
        else:
            print(f"API Error: {e.status} - {e.reason}")
        raise

Endpoint: POST /api/v2/users
Scopes: admin:user, admin:division

Important Note on Roles: The role assigned to the user must have the necessary permissions to access the data you intend to query. For a BPO scenario, you might create a custom role that includes analytics:conversation:read but excludes admin:user or admin:queue. This principle of least privilege is essential for multi-tenant security.

Step 3: Query Data with Division Scope

Once the user is scoped to the division, you can use that user’s credentials (or the original admin client with explicit division filtering) to query data. The most robust method for multi-tenant isolation is to use the divisionId parameter in the API request body or query parameters.

Here is how to query conversation analytics for a specific division.

import purecloudplatformclientv2
from purecloudplatformclientv2.rest import ApiException
from datetime import datetime, timedelta

def get_conversations_by_division(
    client: purecloudplatformclientv2.PureCloudPlatformClientV2,
    division_id: str,
    start_time: datetime,
    end_time: datetime
) -> list:
    """

    Args:
        client: The initialized PureCloud Platform Client.
        division_id: The ID of the division to filter by.
        start_time: Start of the time range.
        end_time: End of the time range.
        
    Returns:
        A list of conversation details.
    """
    try:
        analytics_api = purecloudplatformclientv2.AnalyticsApi(client)
        
        # Define the query body
        query_body = purecloudplatformclientv2.ConversationsDetailsQuery(
            division_ids=[division_id], # Explicitly scope to this division
            interval=f"{start_time.isoformat()}/{end_time.isoformat()}",
            view="conversation",
            group_by=["conversation"]
        )
        
        response = analytics_api.post_analytics_conversations_details_query(
            body=query_body
        )
        
        # Handle pagination if necessary
        conversations = []
        if response.entities:
            conversations.extend(response.entities)
            
        # Check for next page
        while response.next_page:
            response = analytics_api.post_analytics_conversations_details_query(
                body=query_body,
                page_token=response.next_page
            )
            if response.entities:
                conversations.extend(response.entities)
                
        return conversations

    except ApiException as e:
        if e.status == 429:
            print("Rate limit exceeded. Implement exponential backoff.")
        elif e.status == 400:
            print("Bad Request: Check the query body format and time range.")
        else:
            print(f"API Error: {e.status} - {e.reason}")
        raise

Endpoint: POST /api/v2/analytics/conversations/details/query
Scopes: analytics:conversation:read

Why division_ids is critical: Without specifying division_ids, the API returns data for all divisions the authenticated user has access to. In a BPO context, this could lead to data leakage between tenants if the admin account has access to multiple divisions. By explicitly passing division_ids=[division_id], you enforce isolation at the API level.

Complete Working Example

The following script combines all steps into a single executable module. It creates a dedicated user for a BPO tenant, assigns them to a specific division, and then queries conversation data for that division.

Common Errors & Debugging

Error: 403 Forbidden (Access Denied)

Cause: The OAuth client lacks the required scope to access the division or create users.
Fix: Ensure the OAuth client in the Genesys Cloud Admin Console has the following scopes:

• admin:division
• admin:division:read
• admin:user
• analytics:conversation:read

Debug Code:

# Check current scopes by inspecting the token
import jwt

token = client.get_access_token() # Hypothetical method, SDK handles this internally
decoded = jwt.decode(token, options={"verify_signature": False})
print("Current Scopes:", decoded.get('scope', ''))

Error: 409 Conflict (User Already Exists)

Cause: Attempting to create a user with a username that already exists in the organization.
Fix: Implement a check to see if the user exists before creating.

def user_exists(client: purecloudplatformclientv2.PureCloudPlatformClientV2, username: str) -> bool:
    user_api = purecloudplatformclientv2.UserManagementApi(client)
    try:
        user_api.get_users(username=username)
        return True
    except ApiException as e:
        if e.status == 404:
            return False
        raise

Error: 429 Too Many Requests

Cause: Exceeding the API rate limits. Genesys Cloud enforces rate limits per client and per user.
Fix: Implement exponential backoff and retry logic.
