In-App Payments Server Quickstart

This is an example server with a single endpoint of /chargeForCookie for processing payments using Square. The server expects a POST request with a payload of application/json following the format:

{
  "nonce": "INSERT_YOUR_NONCE_HERE"
}

Please replace "INSERT_YOUR_NONCE_HERE" with your own nonce this was generated from either the Square Payment Form or the In-App Payments SDK.
