# Multiple push providers

By default, our Expo plugin expects to be the only push package in your project. It’ll automatically handle push notification metrics and fetch a device tokens for you. But if you use our SDK with other push packages like `react-native-firebase`, you may want to make a couple of configuration changes.

## Use React Native Firebase with the Customer.io SDK[](#use-react-native-firebase-with-the-customerio-sdk)

If you use `react-native-firebase` with the Customer.io SDK, you’ll need to make sure that your `app.json` or `app.config.js` file doesn’t include the `ios.pushNotification.googleServicesFile` option.

This ensures that you properly capture metrics for push notifications sent through Customer.io and any notifications you receive using `react-native-firebase`.

```json
{
   "expo": {
        "ios": {
            // include plist file here
            "googleServicesFile": "./GoogleService-Info.plist"
        },
        "plugins": [
            [
                "customerio-expo-plugin",
                {
                    "android": {
                        "googleServicesFile": "./files/google-services.json"
                    },
                    "ios": {
                        "pushNotification": {
                            "provider": "fcm", 
                            // don't include your plist file here
                        }
                    }
                }
            ]
        ]
    }
}
```

## Capture push tokens from another push provider[](#capture-push-tokens-from-another-push-provider)

If you use another push package like `expo-notifications`, and you want to utilize that package to get device tokens, you’ll need to update your `app.json` or `app.config.js` file to disable automatic device token fetching and make sure you register push tokens with Customer.io using the `CustomerIO.registerDeviceToken(<token>)` method.

1.  In your `app.json` or `app.config.js` file, set the `ios.pushNotification.autoFetchDeviceToken` option to `false`.
    
    ```json
    {
       "plugins": [
          [
             "customerio-expo-plugin",
             {
                "ios": {
                   "pushNotification": {
                      "autoFetchDeviceToken": false
                   }
                }
             }
          ]
       ]
    }
    ```
    
2.  Capture push tokens from the other provider and register them with our SDK using the `CustomerIO.registerDeviceToken(<token>)` method.
