# Flag End-User as a Child

The `IsChild` API helps publishers comply with age-related policies such as [COPPA](https://www.ftc.gov/legal-library/browse/rules/childrens-online-privacy-protection-rule-coppa), [GDPR](https://gdpr-info.eu/), and [Google Play’s Families Ads Program](https://support.google.com/googleplay/android-developer/answer/9893335?sjid=16517989369363894084-EU).

This API enables publishers to flag certain users as children. Children refers to individuals under a certain age, as defined under applicable data privacy laws.

Available from DT FairBid SDK v.3.33.1 and later.

## Calling the API <a href="#h_01je3b4x8yrvev0w0h3nf9nra6" id="h_01je3b4x8yrvev0w0h3nf9nra6"></a>

{% hint style="warning" %}
You must call this API before you initialize the SDK.
{% endhint %}

When you call this API, the [FairBid SDK](/dt-fairbid/fairbid-sdk.md) triggers the respective APIs on the mediated networks that support it:

* Privacy related APIs
* APIs for not tracking the ad ID (in compliance with Google Family program policies)

The [Regulatory Compliance for Mediated Networks](/dt-fairbid/privacy/regulatory-compliance-for-mediated-networks.md) table outlines network compliance levels. This information helps to determine which networks are suitable for the app. It outlines any additional steps required to ensure compliance with applicable laws, mediated network policies, and Play Store policies.

For detailed guidance on calling the API, see [Setting User as Child](/dt-fairbid/fairbid-sdk/sdk-reference/advanced-initialization-options.md#setting-user-as-child).

## 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.digitalturbine.com/dt-fairbid/privacy/flag-end-user-as-a-child.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.
