This guide provides a step-by-step upgrade process from your current installation of Contentsquare Mobile SDK to the latest version of the CSQ SDK.

**CSQ SDK**

The latest version of our SDK provides a unified set of APIs for Product Analytics, Experience Analytics, and Experience Monitoring, eliminating redundant APIs that perform the same actions.

Upgrading to the latest version ensures you benefit from all our newest features and product enhancements.

## Contentsquare React Native SDK v6.0.0 and later

From version 6.0.0 onwards, the Contentsquare React Native SDK makes available the new CSQ SDK.

Update your package.json to use the latest version of the Contentsquare React Native SDK:

* yarn

  ```bash
  yarn add @contentsquare/react-native-bridge@latest
  ```

* npm

  ```bash
  npm install @contentsquare/react-native-bridge@latest
  ```

## Library imports

Replace the Contentsquare SDK import with a CSQ SDK import.

```diff
import Contentsquare from "@contentsquare/react-native-bridge";
import { CSQ } from '@contentsquare/react-native-bridge';
```

Replace ErrorAnalysis import if present:

```diff
import { ErrorAnalysis } from "@contentsquare/react-native-bridge";
import { CSQ } from "@contentsquare/react-native-bridge";
```

Replace masking component import if present:

```diff
import { CSMask } from "@contentsquare/react-native-bridge";
import { CSQMask } from "@contentsquare/react-native-bridge";
```

Replace webView injection component import if present:

```diff
import { CSWebView } from "@contentsquare/react-native-bridge";
import { CSQWebView } from "@contentsquare/react-native-bridge";
```

## SDK start

Start the CSQ SDK manually using `CSQ.start()` — unlike earlier versions, it no longer starts automatically.

```javascript
import { CSQ } from "@contentsquare/react-native-bridge";


useEffect(() => {
    CSQ.start();
}, []);
```

Note

* Android

  (Optional) If you have chosen to deactivate the autostart of the Contentsquare SDK, you can now remove the entry in the manifest, as the CSQ SDK doesn't have an autostart.

  ```xml
  <application>
    ...
      <meta-data
        android:name="com.contentsquare.android.autostart"
        android:value="false"
      />
    ...
  </application>
  ```

* iOS

  (Optional) If you were relying on the Contentsquare SDK autostart, remove the `CSDisableAutostart` property and calls to `Contentsquare.start()`.

  * Swift

    ```xml
    <key>CSDisableAutostart</key>
    <true/>
    ```

    ```swift
    Contentsquare.start()
    ```

  * Objective-C

    ```xml
    <key>CSDisableAutostart</key>
    <true/>
    ```

    ```objc
    [Contentsquare start];
    ```

* Swift

  ```xml
  <key>CSDisableAutostart</key>
  <true/>
  ```

  ```swift
  Contentsquare.start()
  ```

* Objective-C

  ```xml
  <key>CSDisableAutostart</key>
  <true/>
  ```

  ```objc
  [Contentsquare start];
  ```

## Get user consent

The CSQ SDK treats users as opted-out by default.

Implement the [`optIn()`](../command-reference/#csqoptin) API to forward user consent to the SDK and generate a user ID.

```javascript
import React, { useState } from "react";
import { View, Text, Button } from "react-native";
import { CSQ } from "@contentsquare/react-native-bridge";


const PolicyConsentScreen = () => {
  const [isTrackingAccepted, setIsTrackingAccepted] = useState(false);


  const handleAcceptPolicy = () => {
    setIsTrackingAccepted(true);
    CSQ.optIn();
  };


  return (
    <View>
      <Text>Please accept our privacy policy to proceed.</Text>
      <Button title="Accept Policy" onPress={handleAcceptPolicy} />
    </View>
  );
};


export default PolicyConsentScreen;
```

## Update APIs and components

Search and replace all legacy SDK API calls in your app to the latest CSQ APIs using the following mappings. Updating your API calls ensures continued functionality without disruption.

In most cases, this process consists in updating the namespace and method names, with no changes to parameters.

```javascript
Contentsquare.start()
CSQ.start()
```

For more information on SDK methods, see the [SDK API reference](../command-reference/).

## Checklist

Congratulations! You're all set. Use this checklist to ensure everything is correctly updated.

Ensure that you are using a version 6.0.0 or later of the Contentsquare React Native SDK.

Your `import Contentsquare from "@contentsquare/react-native-bridge"` and `import { ErrorAnalysis } from "@contentsquare/react-native-bridge"` declarations have been updated to `import { CSQ } from "@contentsquare/react-native-bridge"`.

You no longer have references to `Contentsquare.` or `ErrorAnalysis.` methods in your codebase.

You no longer have references to `CSMask` or `CSWebView` components in your codebase.

All calls to the CSQ SDK use the `CSQ.`namespace.
