GET /api/v2/oauth/clients returns 403 despite admin scope

GET /api/v2/oauth/clients
403 Forbidden: Insufficient permissions.

My service account has admin:oauthclient:read and admin:oauthclient:view in the token scopes. I am using the Python SDK oauth_client_api.get_oauth_clients(). The token decodes correctly, and I can list users fine. I need to iterate all clients to audit their scope assignments for our Kafka connector setup. Why is the API rejecting a valid admin token for this specific endpoint?

The Python SDK method get_oauth_clients() often strips down the scope set or defaults to a minimal set if not explicitly overridden during the API client instantiation. The 403 usually isn’t about the token itself being invalid, but rather the specific HTTP request not carrying the admin:oauthclient:read scope in the header context that the gateway expects for bulk listing.

Try bypassing the high-level SDK method and using the low-level ApiClient to ensure the headers are explicitly passed. You need to ensure the Authorization header is Bearer prefixed correctly and that you aren’t hitting a rate limit that masquerades as a permission error.

from genesyscloud import ApiClient, Configuration
import jwt

# Assuming you have a valid access token string
access_token = "your_valid_access_token"

config = Configuration()
config.host = "https://api.genesys.cloud"
config.access_token = access_token

# Critical: Ensure the client is configured to pass scopes if the SDK strips them
# Sometimes explicit header injection is needed for sensitive endpoints
api_client = ApiClient(configuration=config)

try:
 # Direct GET request to ensure no SDK wrapper interference
 response = api_client.call_api(
 resource_path='/api/v2/oauth/clients',
 method='GET',
 auth_settings=['OAuth2'],
 header_params={'Authorization': f'Bearer {access_token}'}
 )
 print(response.data)
except Exception as e:
 print(f"Error: {e.status} - {e.reason}")

If this still fails, verify the service account’s role membership. admin:oauthclient:read is required, but the account must also be assigned a role that inherits this scope, such as Organization Admin or a custom role with the specific oauth:client:read permission.

  • Verify role inheritance via /api/v2/authorization/roles
  • Check token expiration vs. rotation timing
  • Ensure the service account is not locked or disabled
  • Review API gateway logs for 403 details
