If your app already has production users, Pushbase provides an API to seamlessly import your existing subscribed devices. This allows you to begin sending push notifications to those devices directly from the Pushbase Dashboard.

​
Preparing Device Data for Import

To enable device segmentation and targeting in Pushbase, each device must conform to the following format. Only the following properties are required: platform, country, language, timezone, and expo_push_token. 
interface Device {
  /** One of React Native mobile  supported OS
   * @see https://gist.github.com/pushbasedev/5bf3c4ad6874d953d6399796cd0c282e
