Installation\n\n```bash\npip install azure-servicebus azure-identity\n```\n\n## Environment Variables\n\n```bash\nSERVICEBUS_FULLY_QUALIFIED_NAMESPACE=\u003Cnamespace>.servicebus.windows.net\nSERVICEBUS_QUEUE_NAME=myqueue\nSERVICEBUS_TOPIC_NAME=mytopic\nSERVICEBUS_SUBSCRIPTION_NAME=mysubscription\n```\n\n## Authentication\n\n```python\nfrom azure.identity import DefaultAzureCredential\nfrom azure.servicebus import ServiceBusClient\n\ncredential = DefaultAzureCredential()\nnamespace = \"\u003Cnamespace>.servicebus.windows.net\"\n\nclient = ServiceBusClient(\n    fully_qualified_namespace=namespace,\n    credential=credential\n)\n```\n\n## Client Types\n\n| Client | Purpose | Get From |\n|--------|---------|----------|\n| `ServiceBusClient` | Connection management | Direct instantiation |\n| `ServiceBusSender` | Send messages | `client.get_queue_sender()` \u002F `get_topic_sender()` |\n| `ServiceBusReceiver` | Receive messages | `client.get_queue_receiver()` \u002F `get_subscription_receiver()` |\n\n## Send Messages (Async)\n\n```python\nimport asyncio\nfrom

with ServiceBusClient(\n        fully_qualified_namespace=\"\u003Cnamespace>.servicebus.windows.net\",\n        credential=credential\n    ) as client:\n        receiver =

await receiver.complete_message(msg)  # Remove from queue\n\nasyncio.run(receive_messages())\n```\n\n## Receive Modes\n\n| Mode | Behavior | Use Case |\n|------|----------|----------|\n| `PEEK_LOCK` (default) | Message locked, must complete\u002Fabandon | Reliable processing |\n| `RECEIVE_AND_DELETE` | Removed immediately on receive | At-most-once delivery |\n\n```python\nfrom azure.servicebus import ServiceBusReceiveMode\n\nreceiver = client.get_queue_receiver(\n    queue_name=\"myqueue\",\n    receive_mode=ServiceBusReceiveMode.RECEIVE_AND_DELETE\n)\n```\n\n## Message Settlement\n\n```python\nasync with receiver:\n    messages = await receiver.receive_messages(max_message_count=1)\n    \n    for msg in messages:\n        try:\n            # Process message...\n            await receiver.complete_message(msg)  # Success - remove from queue\n        except ProcessingError:\n            await receiver.abandon_message(msg)  # Retry later\n        except PermanentError:\n            await receiver.dead_letter_message(\n                msg,\n                reason=\"ProcessingFailed\",\n                error_description=\"Could not process\"\n            )\n```\n\n| Action | Effect |\n|--------|--------|\n| `complete_message()` | Remove from queue (success) |\n| `abandon_message()` | Release lock, retry immediately |\n| `dead_letter_message()` | Move to dead-letter queue |\n| `defer_message()` | Set aside, receive by sequence number |\n\n## Topics and Subscriptions\n\n```python\n# Send to topic\nsender = client.get_topic_sender(topic_name=\"mytopic\")\nasync with sender:\n    await sender.send_messages(ServiceBusMessage(\"Topic message\"))\n\n# Receive from subscription\nreceiver = client.get_subscription_receiver(\n    topic_name=\"mytopic\",\n    subscription_name=\"mysubscription\"\n)\nasync with receiver:\n    messages = await receiver.receive_messages(max_message_count=10)\n```\n\n## Sessions (FIFO)\n\n```python\n# Send with session\nmessage = ServiceBusMessage(\"Session message\")\nmessage.session_id = \"order-123\"\nawait sender.send_messages(message)\n\n# Receive from specific session\nreceiver = client.get_queue_receiver(\n    queue_name=\"session-queue\",\n    session_id=\"order-123\"\n)\n\n# Receive from next available session\nfrom azure.servicebus import NEXT_AVAILABLE_SESSION\nreceiver = client.get_queue_receiver(\n    queue_name=\"session-queue\",\n    session_id=NEXT_AVAILABLE_SESSION\n)\n```\n\n## Scheduled Messages\n\n```python\nfrom datetime import datetime, timedelta, timezone\n\nmessage = ServiceBusMessage(\"Scheduled message\")\nscheduled_time = datetime.now(timezone.utc) + timedelta(minutes=10)\n\n# Schedule message\nsequence_number = await sender.schedule_messages(message, scheduled_time)\n\n# Cancel scheduled message\nawait sender.cancel_scheduled_messages(sequence_number)\n```\n\n## Dead-Letter Queue\n\n```python\nfrom azure.servicebus import ServiceBusSubQueue\n\n# Receive from dead-letter queue\ndlq_receiver = client.get_queue_receiver(\n    queue_name=\"myqueue\",\n    sub_queue=ServiceBusSubQueue.DEAD_LETTER\n)\n\nasync with dlq_receiver:\n    messages = await dlq_receiver.receive_messages(max_message_count=10)\n    for msg in messages:\n        print(f\"Dead-lettered: {msg.dead_letter_reason}\")\n        await dlq_receiver.complete_message(msg)\n```\n\n## Sync Client (for simple scripts)\n\n```python\nfrom azure.servicebus import ServiceBusClient, ServiceBusMessage\nfrom azure.identity import DefaultAzureCredential\n\nwith ServiceBusClient(\n    fully_qualified_namespace=\"\u003Cnamespace>.servicebus.windows.net\",\n    credential=DefaultAzureCredential()\n) as client:\n    with client.get_queue_sender(\"myqueue\") as sender:\n        sender.send_messages(ServiceBusMessage(\"Sync message\"))\n    \n    with client.get_queue_receiver(\"myqueue\") as receiver:\n        for msg in receiver:\n            print(str(msg))\n            receiver.complete_message(msg)\n```\n\n## Best Practices\n\n1. **Use async client** for production workloads\n2. **Use context managers** (`async with`) for proper cleanup\n3. **Complete messages** after successful processing\n4. **Use dead-letter queue** for poison messages\n5. **Use sessions** for ordered, FIFO processing\n6. **Use message batches** for high-throughput scenarios\n7. **Set `max_wait_time`** to avoid infinite blocking\n\n## Reference Files\n\n| File | Contents |\n|------|----------|\n| [references\u002Fpatterns.md](references\u002Fpatterns.md) | Competing consumers,
