Azure Web PubSub Service SDK for Python
Real-time messaging with WebSocket connections at scale.
Installation
# Service SDK (server-side)
pip install azure-messaging-webpubsubservice
# Client SDK (for Python WebSocket clients)
pip install azure-messaging-webpubsubclient
Environment Variables
AZURE_WEBPUBSUB_CONNECTION_STRING=Endpoint=https://<name>.webpubsub.azure.com;AccessKey=...
AZURE_WEBPUBSUB_HUB=my-hub
Service Client (Server-Side)
Authentication
from azure.messaging.webpubsubservice import WebPubSubServiceClient
# Connection string
client = WebPubSubServiceClient.from_connection_string(
connection_string=os.environ["AZURE_WEBPUBSUB_CONNECTION_STRING"],
hub="my-hub"
)
# Entra ID
from azure.identity import DefaultAzureCredential
client = WebPubSubServiceClient(
endpoint="https://<name>.webpubsub.azure.com",
hub="my-hub",
credential=DefaultAzureCredential()
)
Generate Client Access Token
# Token for anonymous user
token = client.get_client_access_token()
print(f"URL: {token['url']}")
# Token with user ID
token = client.get_client_access_token(
user_id="user123",
roles=["webpubsub.sendToGroup", "webpubsub.joinLeaveGroup"]
)
# Token with groups
token = client.get_client_access_token(
user_id="user123",
groups=["group1", "group2"]
)
Send to All Clients
# Send text
client.send_to_all(message="Hello everyone!", content_type="text/plain")
# Send JSON
client.send_to_all(
message={"type": "notification", "data": "Hello"},
content_type="application/json"
)
Send to User
client.send_to_user(
user_id="user123",
message="Hello user!",
content_type="text/plain"
)
Send to Group
client.send_to_group(
group="my-group",
message="Hello group!",
content_type="text/plain"
)
Send to Connection
client.send_to_connection(
connection_id="abc123",
message="Hello connection!",
content_type="text/plain"
)
Group Management
# Add user to group
client.add_user_to_group(group="my-group", user_id="user123")
# Remove user from group
client.remove_user_from_group(group="my-group", user_id="user123")
# Add connection to group
client.add_connection_to_group(group="my-group", connection_id="abc123")
# Remove connection from group
client.remove_connection_from_group(group="my-group", connection_id="abc123")
Connection Management
# Check if connection exists
exists = client.connection_exists(connection_id="abc123")
# Check if user has connections
exists = client.user_exists(user_id="user123")
# Check if group has connections
exists = client.group_exists(group="my-group")
# Close connection
client.close_connection(connection_id="abc123", reason="Session ended")
# Close all connections for user
client.close_all_connections(user_id="user123")
Grant/Revoke Permissions
from azure.messaging.webpubsubservice import WebPubSubServiceClient
# Grant permission
client.grant_permission(
permission="joinLeaveGroup",
connection_id="abc123",
target_name="my-group"
)
# Revoke permission
client.revoke_permission(
permission="joinLeaveGroup",
connection_id="abc123",
target_name="my-group"
)
# Check permission
has_permission = client.check_permission(
permission="joinLeaveGroup",
connection_id="abc123",
target_name="my-group"
)
Client SDK (Python WebSocket Client)
from azure.messaging.webpubsubclient import WebPubSubClient
client = WebPubSubClient(credential=token["url"])
# Event handlers
@client.on("connected")
def on_connected(e):
print(f"Connected: {e.connection_id}")
@client.on("server-message")
def on_message(e):
print(f"Message: {e.data}")
@client.on("group-message")
def on_group_message(e):
print(f"Group {e.group}: {e.data}")
# Connect and send
client.open()
client.send_to_group("my-group", "Hello from Python!")
Async Service Client
from azure.messaging.webpubsubservice.aio import WebPubSubServiceClient
from azure.identity.aio import DefaultAzureCredential
async def broadcast():
credential = DefaultAzureCredential()
client = WebPubSubServiceClient(
endpoint="https://<name>.webpubsub.azure.com",
hub="my-hub",
credential=credential
)
await client.send_to_all("Hello async!", content_type="text/plain")
await client.close()
await credential.close()
Client Operations
| Operation | Description |
|---|---|
get_client_access_token |
Generate WebSocket connection URL |
send_to_all |
Broadcast to all connections |
send_to_user |
Send to specific user |
send_to_group |
Send to group members |
send_to_connection |
Send to specific connection |
add_user_to_group |
Add user to group |
remove_user_from_group |
Remove user from group |
close_connection |
Disconnect client |
connection_exists |
Check connection status |
Best Practices
- Use roles to limit client permissions
- Use groups for targeted messaging
- Generate short-lived tokens for security
- Use user IDs to send to users across connections
- Handle reconnection in client applications
- Use JSON content type for structured data
- Close connections gracefully with reasons
