Audit OAuth Client Scopes in Genesys Cloud Using Python

What You Will Build

• A Python script that retrieves every OAuth client in your Genesys Cloud organization.
• A mechanism to inspect the specific API scopes assigned to each client.
• A final output that maps client names to their granted scopes for security auditing.

Prerequisites

• OAuth Client Type: You need an OAuth client with the admin:oauthclient:read scope. A standard API client with limited scopes will fail to list other clients.
• SDK Version: Genesys Cloud Python SDK genesyscloud version 12.0.0 or higher.
• Language/Runtime: Python 3.8+.
• External Dependencies:
  • genesyscloud: The official Genesys Cloud CX SDK.
  • python-dotenv: For secure environment variable management.

Install the required packages using pip:

pip install genesyscloud python-dotenv

Authentication Setup

Genesys Cloud uses OAuth 2.0 for authentication. The Python SDK handles the token exchange, caching, and refreshing automatically if you provide the client credentials. You must store your credentials in a .env file to avoid hardcoding secrets.

Create a .env file in your project root:

GENESYS_CLOUD_REGION=us-east-1
GENESYS_CLOUD_CLIENT_ID=your-client-id
GENESYS_CLOUD_CLIENT_SECRET=your-client-secret

The SDK initializes the platform client using these environment variables. The region determines the base URL for the API calls (e.g., api.mypurecloud.com for us-east-1).

import os
from dotenv import load_dotenv
from platformclientv2 import ApiClient, Configuration, OauthClientApi

# Load environment variables
load_dotenv()

def initialize_sdk():
    """
    Initializes the Genesys Cloud SDK client using environment variables.
    Returns the ApiClient instance and the OauthClientApi instance.
    """
    # Configure the API client with region and credentials
    configuration = Configuration(
        region=os.getenv("GENESYS_CLOUD_REGION"),
        client_id=os.getenv("GENESYS_CLOUD_CLIENT_ID"),
        client_secret=os.getenv("GENESYS_CLOUD_CLIENT_SECRET")
    )

    # Initialize the API client
    api_client = ApiClient(configuration)

    # Initialize the specific API object for OAuth clients
    oauth_api = OauthClientApi(api_client=api_client)

    return api_client, oauth_api

Implementation

Step 1: Retrieve All OAuth Clients

The primary endpoint for listing OAuth clients is GET /api/v2/oauth/clients. This endpoint supports pagination. To retrieve all clients, you must handle the nextPageUri until it is null.

The SDK method get_oauth_clients abstracts this pagination logic if you use the async wrapper, but for a straightforward script, we will handle the pagination explicitly to demonstrate control over the request cycle.

Required Scope: admin:oauthclient:read

from platformclientv2.rest import ApiException

def list_all_oauth_clients(oauth_api):
    """
    Retrieves all OAuth clients from the organization.
    Handles pagination automatically.
    """
    all_clients = []
    page_size = 100  # Maximum allowed page size for this endpoint
    page_number = 1

    while True:
        try:
            # Make the API call
            response = oauth_api.get_oauth_clients(
                page_size=page_size,
                page_number=page_number
            )

            # Append current page entities to the list
            if response.entities:
                all_clients.extend(response.entities)

            # Check if there are more pages
            if response.next_page_uri is None:
                break

            # Increment page number for the next iteration
            page_number += 1

        except ApiException as e:
            print(f"Exception when calling OauthClientApi->get_oauth_clients: {e}")
            if e.status == 401:
                print("Error: Unauthorized. Check your client credentials and scopes.")
            elif e.status == 403:
                print("Error: Forbidden. Ensure the client has 'admin:oauthclient:read' scope.")
            elif e.status == 429:
                print("Error: Rate Limited. Wait before retrying.")
            raise e

    return all_clients

Step 2: Inspect Scope Assignments

Each OauthClient entity contains a scopes field. This field is a list of strings representing the API scopes granted to that client. For example, ["admin:analytics:read", "user:messages:send"].

Some clients may have no scopes assigned (empty list), which is common for client credentials flow clients that rely on role-based permissions rather than explicit scope grants, or for clients that have not been configured yet.

We will create a helper function to process each client and extract the relevant information: ID, Name, Type, and Scopes.

def process_client_data(clients):
    """
    Processes a list of OauthClient objects and extracts key information.
    Returns a list of dictionaries with client details.
    """
    client_audit_data = []

    for client in clients:
        # Extract basic info
        client_info = {
            "id": client.id,
            "name": client.name,
            "type": client.type,
            "description": client.description,
            "scopes": client.scopes if client.scopes else []
        }

        client_audit_data.append(client_info)

    return client_audit_data

Step 3: Filter and Report

To make the output useful, we will filter for clients that have specific sensitive scopes. For example, you might want to audit any client with admin:* scopes. We will also generate a summary report.

def generate_audit_report(client_data, sensitive_scope_prefix="admin:"):
    """
    Generates a report highlighting clients with sensitive scopes.
    """
    report = []
    sensitive_clients = []

    for client in client_data:
        has_sensitive_scope = any(
            scope.startswith(sensitive_scope_prefix) 
            for scope in client["scopes"]
        )

        entry = {
            "name": client["name"],
            "id": client["id"],
            "type": client["type"],
            "scope_count": len(client["scopes"]),
            "scopes": client["scopes"],
            "has_sensitive_scope": has_sensitive_scope
        }

        report.append(entry)

        if has_sensitive_scope:
            sensitive_clients.append(entry)

    return report, sensitive_clients

Complete Working Example

Common Errors & Debugging

Error: 403 Forbidden

Cause: The OAuth client used to run the script does not have the admin:oauthclient:read scope.
Fix:

1. Go to the Genesys Cloud Admin portal.
2. Navigate to Security > OAuth Clients.
3. Edit the client used in the script.
4. In the Scopes tab, add admin:oauthclient:read.
5. Save the changes.

Error: 401 Unauthorized

Cause: Invalid client ID, client secret, or region.
Fix:

1. Verify the GENESYS_CLOUD_CLIENT_ID and GENESYS_CLOUD_CLIENT_SECRET in your .env file match the Genesys Cloud admin console exactly.
2. Ensure the GENESYS_CLOUD_REGION is correct (e.g., us-east-1, eu-west-1).
3. Check for trailing whitespace in the environment variables.

Error: 429 Too Many Requests

Cause: The API rate limit has been exceeded.
Fix: Implement exponential backoff. The SDK does not automatically retry 429s in all versions. You can add a simple sleep loop:

import time

def get_oauth_clients_with_retry(oauth_api, page_size, page_number, retries=3):
    for attempt in range(retries):
        try:
            return oauth_api.get_oauth_clients(page_size=page_size, page_number=page_number)
        except ApiException as e:
            if e.status == 429:
                wait_time = 2 ** attempt  # Exponential backoff
                print(f"Rate limited. Retrying in {wait_time} seconds...")
                time.sleep(wait_time)
            else:
                raise e
    raise Exception("Max retries exceeded for 429 error")

Error: AttributeError: 'NoneType' object has no attribute 'entities'

Cause: The API call returned None or an unexpected structure, often due to network issues or SDK version mismatch.
Fix: Ensure you are using the latest version of the genesyscloud SDK. Add a check for response before accessing response.entities:

if response is None:
    raise Exception("API returned None. Check network connection or SDK version.")
