# Mobile SDKs

{% hint style="info" %}
**About our Mobile SDKs:** Engine's Mobile SDKs embed the full Engine journey directly inside your mobile app. It's a complete in-app experience configured and tracked through native props and event callbacks.

The Engine SDKenders full-screen inside your app and communicates with your code through native configuration and event callbacks. 

It is **not** a link-out to an external browser.
{% endhint %}

## How the SDKs are built

Engine's Mobile SDKs render the full Engine marketplace experience directly inside your app, configured and tracked through native props and event callbacks. You get the same integration model — the `channel`/`zone`/`productTypes` props and `onInitialize`/`onSubmit`/`onOfferClick`/`onExit` events — across React Native, Flutter, Swift, and Kotlin, so behavior and event data stay consistent everywhere.

# 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://even-financial.gitbook.io/developer-center/marketplace-integrations/mobile-sdks.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.
