# Customizing Survey Behavior

### Showing a Welcome Screen

You can show your users a welcome screen before a survey rather than asking the first question immediately. By default, this is disabled. To enable the survey welcome screen, use the following method.

{% code title="Dart" %}

```dart
Surveys.setShouldShowWelcomeScreen(true);
```

{% endcode %}

### Integrating with Slack

If you have an already existing Slack integration, or are going to create one, you can enable auto-forwarding of Survey responses. If enabled, all NPS Survey score responses as well as Custom Survey responses will be forwarded to your Slack integration on the channel of your choosing.

Forwarded NPS responses will display user email, responses, and score, while Custom Survey responses will display the user email and every question and its response. You'll also have the option to reply to the user which will redirect you to the chat window to reply to that user.

### Setting App Store URL

While the SDK will normally automatically link to your application on the app store when needed, if your application is limited to certain regions, the automatic linking might not work. In these cases, we suggest using the API below to manually set the URL of your application in the store.

{% code title="Dart" %}

```dart
Surveys.setAppStoreURL('URL');
```

{% endcode %}

## 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/flutter/setup-luciq-for-flutter/setup-in-app-surveys/customizing-survey-behavior.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.
