# Expo Push

> Learn how to use the Expo push provider to send push notifications using Novu

[Expo Push](https://docs.expo.dev/push-notifications/overview/) is a notification delivery service provided by Expo.

To enable Expo Push integration, you need to create an [Expo Application Services (EAS)](https://expo.dev/)account and generate an access token in the EAS dashboard.

The overrides field supports all [Message Request](https://docs.expo.dev/push-notifications/sending-notifications/#message-request-format) values. An example of the same follows:

```jsx theme={null}
import { Novu } from '@novu/node';

const novu = new Novu("<NOVU_API_KEY>");

novu.trigger('<WORKFLOW_TRIGGER_IDENTIFIER>', {
  to: {
    subscriberId: '<SUBSCRIBER_ID>',
  },
  payload: {
    abc: 'def',
  },
});
```

Before triggering the notification to a subscriber(user) with push as a step in the workflow, make sure you have added the subscriber's device token as follows:

  <Tab title="Node.js">
    ```javaScript theme={null}
    import {
      Novu,PushProviderIdEnum
    } from '@novu/node';

    const novu = new Novu("<NOVU_API_KEY>");

    await novu.subscribers.setCredentials('subscriberId', PushProviderIdEnum.EXPO, {
      deviceTokens: ['token1', 'token2'],
    });
    ```
  </Tab>

  <Tab title="cURL">
    ```bash theme={null}
    curl -L -X PUT 'https://api.novu.co/v1/subscribers/<SUBSCRIBER_ID>/credentials' \
    -H 'Content-Type: application/json' \
    -H 'Accept: application/json' \
    -H 'Authorization: ApiKey <NOVU_API_KEY>' \
    -d '{
      "providerId": "expo",
      "deviceTokens": ["token1", "token2"],
      "integrationIdentifier": "expo-MnGLxp8uy"
    }'
    ```
  </Tab>
</Tabs>
