# Step 3: Install the React Native SDK

Next, we can embed the SDK in your React Native app to
store card details, authorize payments, and capture a transaction.

## Add the SDK

The [React Native SDK](https://github.com/gr4vy/gr4vy-react-native) is available as an NPM package.

```sh theme={"dark"}
yarn add @gr4vy/embed-react-native
# OR
npm install @gr4vy/embed-react-native
```

This will install the SDK, as well as the native iOS and Android dependencies.
