How to List All OAuth Clients in an Org and Check Their Scope Assignments Programmatically

What You Will Build

• A Python script that retrieves every OAuth client application registered in a Genesys Cloud CX organization.
• Logic that iterates through each client to extract and validate assigned OAuth scopes against a required permission set.
• Implementation using the Genesys Cloud Python SDK (genesyscloud) with production-grade error handling and pagination.

Prerequisites

• OAuth Client Type: Service Account or JWT Service Account with the admin:oauthclient:read scope.
• SDK Version: genesyscloud >= 2.0.0 (Python).
• Language/Runtime: Python 3.8+.
• External Dependencies:
  • genesyscloud: The official Genesys Cloud CX Python SDK.
  • python-dotenv (optional): For managing environment variables securely.

Install the SDK via pip:

pip install genesyscloud python-dotenv

Authentication Setup

The Genesys Cloud SDK handles OAuth2 token management automatically. You must provide a client ID, client secret, and the API host (usually api.mypurecloud.com for US regions). The SDK caches the token and refreshes it when it expires.

Create a .env file in your project root:

GENESYS_CLIENT_ID=your_client_id_here
GENESYS_CLIENT_SECRET=your_client_secret_here
GENESYS_API_HOST=api.mypurecloud.com

Initialize the API client in your code. This step establishes the connection and validates your credentials.

import os
from dotenv import load_dotenv
from purecloudplatform.client.configuration import Configuration
from purecloudplatform.client.api_client import ApiClient

# Load environment variables
load_dotenv()

def get_api_client() -> ApiClient:
    """
    Initializes and returns a configured Genesys Cloud API Client.
    Raises ValueError if required environment variables are missing.
    """
    client_id = os.getenv("GENESYS_CLIENT_ID")
    client_secret = os.getenv("GENESYS_CLIENT_SECRET")
    api_host = os.getenv("GENESYS_API_HOST", "api.mypurecloud.com")

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

    # Configure the client
    configuration = Configuration(
        host=f"https://{api_host}",
        client_id=client_id,
        client_secret=client_secret
    )
    
    # Create the API client instance
    api_client = ApiClient(configuration)
    return api_client

Implementation

Step 1: Retrieve All OAuth Clients

The endpoint for listing OAuth clients is paginated. The Genesys Cloud API returns a maximum of 100 items per page by default, though you can request up to 500. To ensure you capture every client in large organizations, you must implement pagination logic.

The SDK method is get_oauth_client_list. It returns a OAuthClientListResponse object containing an entities list and a next_page URL.

Required Scope: admin:oauthclient:read

from purecloudplatform.client.api.oauth_api import OAuthApi
from purecloudplatform.client.rest import ApiException
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

def list_all_oauth_clients(api_client: ApiClient) -> list:
    """
    Fetches all OAuth clients from the Genesys Cloud organization using pagination.
    
    Args:
        api_client: An initialized ApiClient instance.
        
    Returns:
        A list of OAuthClient objects.
    """
    oauth_api = OAuthApi(api_client)
    all_clients = []
    
    # Initial request with maximum page size
    page_size = 500
    page_number = 1
    
    try:
        while True:
            logger.info(f"Fetching OAuth clients page {page_number}...")
            
            # Call the API
            response = oauth_api.get_oauth_client_list(
                page_size=page_size,
                page_number=page_number
            )
            
            # Append entities to the master list
            if response.entities:
                all_clients.extend(response.entities)
                logger.info(f"Retrieved {len(response.entities)} clients on this page.")
            else:
                logger.info("No more clients found.")
                break
            
            # Check if there is a next page
            if not response.next_page:
                logger.info("No next page URL. Pagination complete.")
                break
            
            # Extract page number from next_page URL or increment manually
            # The SDK response usually provides the next page URL, but the 
            # get_oauth_client_list method doesn't automatically follow it.
            # We manually increment page_number for the next iteration.
            page_number += 1

    except ApiException as e:
        logger.error(f"API Exception when listing OAuth clients: {e.status} - {e.reason}")
        if e.status == 401:
            logger.error("Authentication failed. Check Client ID and Secret.")
        elif e.status == 403:
            logger.error("Forbidden. Ensure the service account has 'admin:oauthclient:read' scope.")
        raise
    except Exception as e:
        logger.error(f"Unexpected error: {e}")
        raise

    logger.info(f"Total OAuth clients retrieved: {len(all_clients)}")
    return all_clients

Step 2: Extract and Validate Scopes

Each OAuthClient object contains a scopes attribute, which is a list of strings representing the permissions granted to that client. To audit these clients, you often need to check if they possess specific high-risk scopes or if they are missing required scopes for a specific integration.

We will create a validation function that checks each client against a dictionary of required scope sets.

from typing import Dict, List, Optional

def audit_client_scopes(
    clients: List, 
    required_scopes_map: Dict[str, List[str]]
) -> Dict[str, Dict]:
    """
    Audits OAuth clients against a map of required scopes.
    
    Args:
        clients: List of OAuthClient objects.
        required_scopes_map: Dictionary where keys are client names/IDs and values 
                             are lists of required scopes.
                             
    Returns:
        A dictionary mapping client ID to audit results.
    """
    audit_results = {}
    
    for client in clients:
        client_id = client.id
        client_name = client.name
        client_scopes = set(client.scopes) if client.scopes else set()
        
        # Initialize result for this client
        result = {
            "name": client_name,
            "client_type": client.client_type,
            "all_scopes": client_scopes,
            "missing_scopes": [],
            "has_required": True
        }
        
        # Check if this client is in the required_scopes_map
        # We can match by name or ID. Here we try name first, then ID.
        required_scopes = None
        if client_name in required_scopes_map:
            required_scopes = required_scopes_map[client_name]
        elif client_id in required_scopes_map:
            required_scopes = required_scopes_map[client_id]
            
        if required_scopes:
            # Calculate missing scopes
            missing = set(required_scopes) - client_scopes
            if missing:
                result["missing_scopes"] = list(missing)
                result["has_required"] = False
        
        audit_results[client_id] = result
        
    return audit_results

Step 3: Processing Results and Reporting

After auditing, you need to format the output for consumption. This could be a JSON file for another system or a console report for a developer. We will generate a JSON summary that highlights clients failing the scope check.

import json

def generate_audit_report(audit_results: Dict) -> str:
    """
    Generates a JSON string report of the audit results.
    Only includes clients that are missing required scopes or have high-risk scopes.
    """
    flagged_clients = {}
    
    for client_id, data in audit_results.items():
        # Flag clients missing required scopes
        if not data["has_required"]:
            flagged_clients[client_id] = {
                "name": data["name"],
                "type": data["client_type"],
                "missing_scopes": data["missing_scopes"],
                "current_scopes": list(data["all_scopes"])
            }
            
        # Optional: Flag clients with dangerous scopes (e.g., admin:*)
        dangerous_scopes = {"admin:*", "user:*"}
        if dangerous_scopes.intersection(data["all_scopes"]):
            if client_id not in flagged_clients:
                flagged_clients[client_id] = {
                    "name": data["name"],
                    "type": data["client_type"],
                    "dangerous_scopes_found": list(dangerous_scopes.intersection(data["all_scopes"])),
                    "current_scopes": list(data["all_scopes"])
                }
            else:
                flagged_clients[client_id]["dangerous_scopes_found"] = list(
                    dangerous_scopes.intersection(data["all_scopes"])
                )

    return json.dumps(flagged_clients, indent=2)

Common Errors & Debugging

Error: 403 Forbidden

Cause: The service account used for authentication lacks the admin:oauthclient:read scope.

Fix:

1. Navigate to the Genesys Cloud Admin UI.
2. Go to Security > OAuth.
3. Find your service account client.
4. Click Edit.
5. In the Scopes tab, search for admin:oauthclient:read and add it.
6. Save the changes. Note: You may need to regenerate the client secret if you are using a JWT service account and the certificate has changed, but scope updates usually take effect immediately for new tokens.

Error: 429 Too Many Requests

Cause: You are hitting the API rate limit. The Genesys Cloud API enforces rate limits per client ID. Fetching large pages or rapid successive calls can trigger this.

Fix:
Implement exponential backoff. The Genesys Cloud Python SDK does not automatically retry 429s in all versions, so you must handle it explicitly.

import time

def fetch_with_retry(api_client, api_call_func, *args, max_retries=3):
    for attempt in range(max_retries):
        try:
            return api_call_func(*args)
        except ApiException as e:
            if e.status == 429:
                wait_time = 2 ** attempt
                logger.warning(f"Rate limited. Waiting {wait_time} seconds...")
                time.sleep(wait_time)
            else:
                raise
    raise Exception("Max retries exceeded for 429 error")

Error: AttributeError: ‘NoneType’ object has no attribute ‘entities’

Cause: The API call returned a response object, but the entities field is None or missing because the response structure changed or an unexpected error occurred that was not raised as an ApiException.

Fix:
Always check if response is not None and if response.entities exists before iterating. The code above includes this check:

if response.entities:
    all_clients.extend(response.entities)
