# Update queue settings

> Updates the queue settings of an instance, allowing control over message enqueue behavior when disconnected.

## Concept

This method allows updating settings related to the message queue behavior of an instance.

Currently, it is possible to configure whether the instance should accept new messages in the queue while disconnected.

***

## Attributes

### Required

<ParamField path="instanceId" type="string" required>
  Your instance ID. Available in the Z-API panel under **Instances**.
</ParamField>

<ParamField path="token" type="string" required>
  Your Z-API instance token.
</ParamField>

### Body (Required)

<ParamField body="disableEnqueueWhenDisconnected" type="boolean">
  Defines whether the instance should block message enqueueing when it is disconnected.
</ParamField>

***

## Request Body

```json theme={"theme":{"light":"github-light","dark":"poimandres"}}
{
  "disableEnqueueWhenDisconnected": true
}
```

## Queue behavior

* By default, Z-API allows sending messages to the queue even when the instance does not have a connected number
* When `disableEnqueueWhenDisconnected` is `true`, new messages will not be added to the queue while the instance is disconnected
* When `disableEnqueueWhenDisconnected` is `false`, the default behavior is maintained (messages continue to be enqueued even when disconnected)
* This setting is useful to prevent message accumulation in the queue when an instance is reused without a connected number

## Response

### 200

```json theme={"theme":{"light":"github-light","dark":"poimandres"}}
{
  "success": true
}
```
