Could someone explain why I am getting a 403 Forbidden error when calling /api/v2/routing/queues?
I am using the standard genesyscloud client with a token that works for other endpoints. My token request includes routing:queue:view and routing:queue:read scopes, but the API still rejects the request.
You need to verify the actual scopes granted in the JWT payload, as routing:queue:read is often a logical grouping that does not automatically include routing:queue:view. In my experience with HashiCorp Vault integrations, the token issuance step sometimes truncates scope lists if the client secret lacks the specific permission to request that view scope.
First, decode your JWT using a tool like jwt.io. Check the scope claim. If routing:queue:view is missing, the 403 is expected. If it is present, check for typos in the SDK configuration. The Python SDK requires explicit scope validation during initialization.
Here is a robust way to initialize the client with strict scope checking:
from purecloudplatformclientv2 import Configuration, ApiClient
from purecloudplatformclientv2.rest import ApiException
config = Configuration(
host="https://api.mypurecloud.com",
access_token="your_jwt_here"
)
# Validate scopes before making the call
required_scopes = ["routing:queue:view", "routing:queue:read"]
current_scopes = config.access_token.split() if hasattr(config, 'access_token') else []
if not all(s in current_scopes for s in required_scopes):
raise ValueError("Missing required scopes: {}".format(required_scopes))
api_client = ApiClient(configuration=config)
routing_api = api_client.api_client.call_api(
'/api/v2/routing/queues', 'GET',
response_type='QueueEntityListing'
)
Also, ensure your client ID in Vault has the routing:queue:view scope enabled in the Genesys Cloud Admin console under Security > OAuth Applications. A common pitfall is updating the client secret rotation policy but forgetting to update the associated scope permissions in the platform. See this guide for scope mapping: https://support.genesys.com/articles/oauth-scope-mapping-guide.
I normally fix this by checking the client credentials configuration directly in the Genesys Cloud admin console. The error often stems from the app lacking the specific routing:queue:view permission, not just the read scope.
Verify the OAuth client settings. Ensure the Client ID has the correct permissions assigned. A quick restart of the token flow after updating permissions usually resolves the 403 Forbidden issue immediately.
403 is an OAuth scope issue, not a WebSocket one. Verify the token payload contains routing:queue:view.
# Verify scopes before calling
import jwt
decoded = jwt.decode(token, options={"verify_signature": False})
assert "routing:queue:view" in decoded.get("permissions", [])

I think the issue isn’t just about the scopes present in the JWT, but rather how the Python SDK handles the token refresh cycle when multiple scopes are requested versus granted. You might be getting a partial grant where routing:queue:read succeeds but routing:queue:view is silently dropped if the client credentials don’t explicitly allow the view permission at the app level, causing the SDK to reuse a stale or insufficient token for subsequent calls.
Check your token response object directly before passing it to the API client. The SDK often caches tokens, so if the initial grant was incomplete, it won’t automatically retry with a corrected scope list. Here is how you can verify the actual granted scopes in the token payload using the Python SDK’s internal token store or by decoding it manually:
import jwt
import base64
def verify_queue_scopes(token):
# Decode the JWT payload without signature verification for inspection
payload = jwt.decode(token, options={"verify_signature": False})
# Check for the specific view scope required for listing queues
granted_perms = payload.get('permissions', [])
if 'routing:queue:view' not in granted_perms:
raise PermissionError(f"Missing required scope 'routing:queue:view'. Granted: {granted_perms}")
return True
# Usage before making the API call
try:
verify_queue_scopes(current_access_token)
# Proceed with API call
except PermissionError as e:
print(f"Scope mismatch: {e}")
# Trigger a new token request with explicit scope list
Ensure your OAuth client in the Genesys Cloud admin console has both routing:queue:read and routing:queue:view explicitly checked, then clear your SDK’s token cache to force a fresh grant.
