# Azure Service Bus Queues Binding Spec

```yaml
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: bindings.azure.servicebusqueues
  metadata:
  - name: connectionString
    value: "sb://************"
  - name: queueName
    value: queue1
  - name: ttlInSeconds
    value: 60
```

- `connectionString` is the Service Bus connection string.
- `queueName` is the Service Bus queue name.
- `ttlInSeconds` is an optional parameter to set the default message [time to live](https://docs.microsoft.com/azure/service-bus-messaging/message-expiration). If this parameter is omitted, messages will expire after 14 days.

> **Note:** In production never place passwords or secrets within Dapr components. For information on securely storing and retrieving secrets refer to [Setup Secret Store](../../../howto/setup-secret-store)

## Specifying a time to live on message level

Time to live can be defined on queue level (as illustrated above) or at the message level. The value defined at message level overwrites any value set at queue level.

To set time to live at message level use the `metadata` section in the request body during the binding invocation.

The field name is `ttlInSeconds`.

Example:

```shell
curl -X POST http://localhost:3500/v1.0/bindings/myServiceBusQueue \
  -H "Content-Type: application/json" \
  -d '{
        "data": {
          "message": "Hi"
        },
        "metadata": {
          "ttlInSeconds": "60"
        }
      }'
```
