# Set Received-Reply Handler

API reference for the Luciq received-reply handler. Register a callback that fires when a new reply is received from your support team.

Use this handler to run specific code each time a new message is received by the SDK.

This block is executed each time a new message is received. This can be used to show your own UI when a new message is received when default chat notifications are disabled, for example.

{% tabs fullWidth="true" %}
{% tab title="iOS - Swift" %}

```swift
Replies.didReceiveReplyHandler = {
    // Notify users about new message.
}
```

{% endtab %}

{% tab title="iOS - ObjC" %}

```objectivec
LCQReplies.didReceiveReplyHandler = ^{
    // Notify users about new message.
};
```

{% endtab %}

{% tab title="And - Java" %}

```java
Replies.setOnNewReplyReceivedCallback(new Runnable() {
	//Your code goes here.
});
```

{% endtab %}

{% tab title="And - Kotlin" %}

```kotlin
Replies.setOnNewReplyReceivedCallback(new Runnable() {
  @Override
  public void run() {
    //Show an alert to notify users about a new message.
  }
});
```

{% endtab %}

{% tab title="RN" %}

```javascript
Replies.setOnNewReplyReceivedHandler(function () {
    //Create custom alert
});
```

{% endtab %}

{% tab title="Flutter" %}

```dart
Replies.setOnNewReplyReceivedCallback(Function function);
```

{% endtab %}
{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.luciq.ai/references/sdk-event-handlers/set-on-new-message-handler.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
