How to List All OAuth Clients and Audit Scope Assignments in Genesys Cloud

What You Will Build

• This tutorial demonstrates how to retrieve a complete list of OAuth clients within a Genesys Cloud organization using the Python SDK.
• It uses the PureCloudPlatformClientV2 SDK to call the /api/v2/oauth/clients endpoint and parse the resulting JSON payload.
• The code extracts client names, client IDs, and associated OAuth scopes to enable programmatic auditing of permission assignments.

Prerequisites

• OAuth Client Type: Service Account or Resource Owner Password flow with the scope oauth:client:read.
• SDK Version: genesys-cloud-sdk-python version 138.0.0 or later.
• Language/Runtime: Python 3.9+.
• Dependencies:

  pip install purecloud-platform-client-v2
  

Authentication Setup

Genesys Cloud uses OAuth 2.0 for API authentication. For server-to-server operations like auditing clients, a Service Account is the standard approach. You must configure a Service Account in the Genesys Cloud Admin portal with the oauth:client:read scope before running this code.

The following code initializes the SDK and authenticates using a Service Account. It caches the token to avoid unnecessary refresh calls during the script execution.

import os
import sys
from purecloud_platform_client_v2 import PlatformClient, Configuration
from purecloud_platform_client_v2.rest import ApiException

def get_platform_client() -> PlatformClient:
    """
    Initializes and returns an authenticated Genesys Cloud PlatformClient.
    Uses environment variables for security.
    """
    # Load credentials from environment variables
    client_id = os.getenv("GENESYS_CLIENT_ID")
    client_secret = os.getenv("GENESYS_CLIENT_SECRET")
    environment = os.getenv("GENESYS_ENVIRONMENT", "my.genesys.cloud")  # Default to US

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

    # Configure the SDK
    configuration = Configuration(
        client_id=client_id,
        client_secret=client_secret,
        environment=environment
    )

    # Create the platform client instance
    platform_client = PlatformClient(configuration)

    # Force authentication to ensure token is valid
    try:
        platform_client.oauth_client.authenticate()
    except ApiException as e:
        print(f"Authentication failed: {e.status} {e.reason}", file=sys.stderr)
        raise

    return platform_client

if __name__ == "__main__":
    try:
        client = get_platform_client()
        print("Successfully authenticated with Genesys Cloud.")
    except Exception as e:
        print(f"Error during setup: {e}", file=sys.stderr)
        sys.exit(1)

Implementation

Step 1: Retrieve the List of OAuth Clients

The core API endpoint for this task is GET /api/v2/oauth/clients. In the Python SDK, this is exposed via the OAuthApi class. The endpoint supports pagination, so we must handle the page_size and page_number parameters to ensure we retrieve all clients if the organization has more than the default page size (typically 25 or 50).

from purecloud_platform_client_v2.api import OAuthApi
from purecloud_platform_client_v2.models import GetOauthClientsResponse

def list_all_oauth_clients(platform_client: PlatformClient) -> list[GetOauthClientsResponse]:
    """
    Retrieves all OAuth clients from the organization.
    Handles pagination to ensure all clients are fetched.
    """
    oauth_api = OAuthApi(platform_client)
    all_clients = []
    page_number = 1
    page_size = 100  # Max allowed page size is often 100 or 200 depending on endpoint limits

    while True:
        try:
            # Call the API
            response = oauth_api.post_oauth_clients_query(
                body={
                    "page_size": page_size,
                    "page_number": page_number
                }
            )

            # Append current page clients
            if response.entities:
                all_clients.extend(response.entities)

            # Check if there are more pages
            if response.page_number >= response.total_pages:
                break
            
            page_number += 1

        except ApiException as e:
            print(f"API Error {e.status}: {e.reason}", file=sys.stderr)
            if e.status == 429:
                print("Rate limit hit. Retrying in 5 seconds...", file=sys.stderr)
                import time
                time.sleep(5)
                continue
            else:
                raise

    return all_clients

Expected Response Structure:
The post_oauth_clients_query method returns a GetOauthClientsResponse object. The entities list contains OAuthClient objects. Each OAuthClient object has the following key attributes:

• id: The unique identifier of the OAuth client.
• name: The display name of the client.
• client_id: The public client identifier.
• scopes: A list of strings representing the assigned OAuth scopes.
• type: The type of client (e.g., service, user).

Step 2: Parse and Audit Scope Assignments

Once the list of clients is retrieved, we need to parse the scope assignments. This step is critical for security audits. We will create a function that extracts the client name, ID, and scopes, and flags any clients with overly permissive scopes (e.g., * or admin:all).

from typing import List, Dict

def audit_client_scopes(clients: list) -> List[Dict]:
    """
    Parses the list of OAuth clients and extracts scope information.
    Flags clients with dangerous scopes.
    """
    audit_results = []
    dangerous_scopes = ["*", "admin:all", "user:all"]

    for client in clients:
        client_info = {
            "client_id": client.client_id,
            "name": client.name,
            "type": client.type,
            "scopes": client.scopes if client.scopes else [],
            "is_dangerous": False
        }

        # Check for dangerous scopes
        if client.scopes:
            for scope in client.scopes:
                if scope in dangerous_scopes or scope.startswith("admin:"):
                    client_info["is_dangerous"] = True
                    break
        
        audit_results.append(client_info)

    return audit_results

Step 3: Output Results in a Structured Format

For practical use, we output the results as a JSON object. This allows the data to be consumed by other tools, stored in a database, or displayed in a dashboard.

import json

def print_audit_report(audit_results: List[Dict]):
    """
    Prints the audit report in a human-readable format and as JSON.
    """
    print("\n--- OAuth Client Scope Audit Report ---")
    print(f"Total Clients Found: {len(audit_results)}")
    
    dangerous_clients = [c for c in audit_results if c.get("is_dangerous")]
    print(f"Clients with Potential Security Risks: {len(dangerous_clients)}")
    print("-" * 50)

    for client in audit_results:
        status = " [RISK]" if client["is_dangerous"] else " [OK]"
        print(f"ID: {client['client_id']}")
        print(f"Name: {client['name']}")
        print(f"Type: {client['type']}")
        print(f"Scopes: {', '.join(client['scopes'])}")
        print(f"Status:{status}")
        print("-" * 50)

    # Output full JSON for machine consumption
    print("\n--- Full JSON Output ---")
    print(json.dumps(audit_results, indent=2))

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: The OAuth token is invalid, expired, or the client credentials are incorrect.
• Fix: Verify that GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET are correct. Ensure the Service Account has not been disabled. Check that the token refresh logic in the SDK is functioning by calling platform_client.oauth_client.authenticate() explicitly.

Error: 403 Forbidden

• Cause: The authenticated Service Account does not have the required oauth:client:read scope.
• Fix: Log in to the Genesys Cloud Admin portal, navigate to Manage > Integrations > OAuth, select the Service Account, and ensure oauth:client:read is checked under the Scopes section. Save the changes and regenerate the token.

Error: 429 Too Many Requests

• Cause: The API rate limit has been exceeded. This is common when iterating through large datasets or making rapid successive calls.
• Fix: Implement exponential backoff. The provided code includes a basic retry mechanism for 429 errors. For production systems, use a library like tenacity to handle retries with jitter.

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

• Cause: The API call returned None or an unexpected structure, often due to a network error or SDK version mismatch.
• Fix: Ensure you are using the latest version of purecloud-platform-client-v2. Add logging to inspect the raw response if the issue persists.
