# 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 by asking a question.

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

```
GET https://even-financial.gitbook.io/developer-center/marketplace-integrations/mobile-sdks.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.
