This example uses the XcooBee Payments SDK for react native. Please clone to a directory on your system or copy example files from the SDK into separate directory.
This example project was build with Expo but you can also use CRA.
So you will also need the Expo command line tools.
yarn install expo-cli --global
Information about SDK and its API is available in SDK Repo.
Please see SDK

expo start
You can use npm as alternate package manager.
