Using "Azure Web PubSub Service SDK for Python". Generate a client access token for user 'user123' with group membership

Expected outcome:

Token generated with URL endpoint and user ID. User is assigned to groups 'group1' and 'group2' with sendToGroup and joinLeaveGroup roles.

Using "Azure Web PubSub Service SDK for Python". Send a notification to all connected clients

Expected outcome:

Message broadcast successfully to all connections in the hub. Content type set to application/json with notification payload.

What You Can Build

Live chat application

Build a real-time chat system where users can send and receive messages instantly through WebSocket connections.

Real-time dashboard updates

Push live data updates to connected dashboard clients without polling, using group-based message routing.

Multiplayer game networking

Enable low-latency communication between game clients using WebSocket connections with user-based targeting.

Try These Prompts

Basic setup 
Help me set up the Azure Web PubSub Service client in Python using a connection string. I need to send messages to all connected clients.
User authentication 
Generate a client access token for user 'alice' with permissions to join groups and send messages. Use Azure Entra ID authentication.
Group messaging 
Show me how to add users to groups and send targeted messages to specific groups in Azure Web PubSub.
Async broadcast 
Create an async function that broadcasts a JSON message to all connections and handles graceful shutdown of the client and credentials.

Best Practices

  • Use roles to limit client permissions and follow the principle of least privilege
  • Generate short-lived tokens and implement token refresh mechanisms for security
  • Use group-based messaging for efficient targeted communication instead of broadcasting

Avoid

  • Using connection strings in source code instead of environment variables or Key Vault
  • Granting full permissions to all clients without role-based access control
  • Not handling connection failures or implementing reconnection logic in clients

Frequently Asked Questions

What is the difference between the Service SDK and Client SDK?
The Service SDK is for server-side operations like sending messages and managing connections. The Client SDK is for building WebSocket client applications that connect to the service.
How do I authenticate users for WebSocket connections?
Use get_client_access_token with a user_id parameter. You can authenticate using connection strings or Azure Entra ID credentials.
Can I send messages to specific users instead of broadcasting?
Yes, use send_to_user for individual users or send_to_group for multiple users in a group. This is more efficient than broadcasting.
How do I handle connection disconnections?
Implement event handlers for connection events. Use connection_exists to check status before sending. Implement reconnection logic in client applications.
What content types are supported for messages?
The SDK supports text/plain for simple strings and application/json for structured data. JSON is recommended for complex payloads.
Is there an async version of the SDK?
Yes, import from azure.messaging.webpubsubservice.aio for async operations. This is recommended for high-throughput applications.
