# Set Pre-Sending Handler

Use this handler to run any code right before sending a bug or crash report

This block is executed in the background before sending each report and could be used for attaching logs and extra data to reports, for example.

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

```swift
Luciq.willSendReportHandler = { report in
    report.appendTag("tag1")
    report.logVerbose("Verbose log.")
    report.append(toConsoleLogs: "Console log statement.")
    report.setUserAttribute("value", withKey: "key")
    let data = "Data".data(using: .utf8)
    report.addFileAttachment(with: data)
    
    return report
}
```

{% endtab %}

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

```objectivec
Luciq.willSendReportHandler = ^LCQReport * _Nonnull(LCQReport * _Nonnull report) {
    [report appendTag:@"tag1"];
    [report logVerbose:@"Verbose log."];
    [report appendToConsoleLogs:@"Console log statement"];
    [report setUserAttribute:@"value" withKey:@"key"];

    return report;
};
```

{% endtab %}

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

```java
Luciq.onReportSubmitHandler(new Report.OnReportCreatedListener() {
            @Override
            public void onReportCreated(Report report) {
                
            }
        });
```

{% endtab %}

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

```kotlin
Luciq.onReportSubmitHandler{report -> }
```

{% endtab %}

{% tab title="RN" %}

```javascript
Luciq.onReportSubmitHandler((report) => {
    // Attach logs and extra data to reports.
});
```

{% 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.luciq.ai/references/sdk-event-handlers/set-pre-sending-handler.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
