  Overview

There is no Javascript API for Expo that allows you to directly fetch iOS and Android data for constructing Airbridge Events.

Therefore, you have to follow the steps outlined in the `iOS Guide` and `Android Guide`. Collect data in each platform, and then use Expo’s iOS and Android Fetch API to get the data. Read on and learn how it is done.
