Authentication

from azure.identity import DefaultAzureCredential
from azure.servicebus import ServiceBusClient

credential = DefaultAzureCredential()
namespace = "<namespace>.servicebus.windows.net"

client = ServiceBusClient(
    fully_qualified_namespace=namespace,
    credential=credential
)

Client Types

Client	Purpose	Get From
ServiceBusClient	Connection management	Direct instantiation
ServiceBusSender	Send messages	client.get_queue_sender() / get_topic_sender()
ServiceBusReceiver	Receive messages	client.get_queue_receiver() / get_subscription_receiver()

Send Messages (Async)

import asyncio
from azure.servicebus.aio import ServiceBusClient
from azure.servicebus import ServiceBusMessage
from azure.identity.aio import DefaultAzureCredential

async def send_messages():
    credential = DefaultAzureCredential()
    
    async with ServiceBusClient(
        fully_qualified_namespace="<namespace>.servicebus.windows.net",
        credential=credential
    ) as client:
        sender = client.get_queue_sender(queue_name="myqueue")
        
        async with sender:
            # Single message
            message = ServiceBusMessage("Hello, Service Bus!")
            await sender.send_messages(message)
            
            # Batch of messages
            messages = [ServiceBusMessage(f"Message {i}") for i in range(10)]
            await sender.send_messages(messages)
            
            # Message batch (for size control)
            batch = await sender.create_message_batch()
            for i in range(100):
                try:
                    batch.add_message(ServiceBusMessage(f"Batch message {i}"))
                except ValueError:  # Batch full
                    await sender.send_messages(batch)

                    batch.add_message(ServiceBusMessage(f"Batch message {i}"))
