# Custom Actions

To create an action which calls into native code, use a `link` action type with a deeplink into your app. 

An example link to your "edit profile experience could be: `you-app-scheme:profile/photo?mode=edit`. It has the the following components:

* App scheme `you-app-scheme:`: the app scheme you[ setup and define for your app](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app)
* The path `profile/photo`: a specific screen or action in your app you are linking to
* A query string `?mode=edit`: Any serialized data you want to pass through and handle in your code.

To implement you can use [iOS deeplinks](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app), or [universal links](https://developer.apple.com/ios/universal-links/).

To not set `useEmbeddedBrowser` for deeplinks. This option is only supported for http/https links.
