# External Linking You can open your application using external links and even pass data to your application when it loads. Inside `/app/app.json` you can set the `scheme` to your own app name (eg. gravity), then launch your app using `gravity://` When using Expo in development, the `exp://` scheme will be automatically injected, and your production scheme name will be used when your app is built. You can also pass in a route and parameters like so: ``` gravity://resetpassword?token=xxx ``` For a full example, please refer to the reset password or user invite flow, both of which send a magic link that opens the app. --- # Agent Instructions: 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.
