# Backend Server (Node.js)
This backend server built with Express and Node integrates the Airtable API with:
- the Appian API to update the products delivered in the customer app (see Updating Store Products)
- the Twilio API to alert customers of recent product deliveries (see SMS Notifications with Twilio)
Both processes are executed once a day through a scheduled daily job via Heroku.
Here are some of the affected views in the customer application.
