# Pay with Pi App

Pay with Pi App is an example of how you can implement the various required flows in your app's code.
It aims to show you how to use Pay with Pi Platform API on the backend side and Pay with Pi SDK on the frontend side of your app.


It is composed of two major parts:

* **backend**: a backend app (a very simple JSON API built using Node and ExpressJS)
* **frontend**: a single-page frontend app (built using React and create-react-app)


## Initial Development

> **WARNING**
>
> The demo app uses express session cookies which, in the Sandbox environment, are not correctly saved on the client on some browsers.
> To properly test all of the features of the Pay with Pi App, we recommend you to open the sandbox app using Pi browser.
