A simple app written in node.js (and, marginally designed to run on Heroku). This listens for charge.succeeded webhooks from Stripe, and then prints a message (and plays a sound) in any browser connected to the server. For info on setting up on heroku, see this tutorial: http://devcenter.heroku.com/articles/node-js Install dependencies with: npm install . Run with: node server.js Open in browser with: http://localhost:8080 Add your stripe api key to your env: heroku config:add STRIPE_SECRET_KEY=<YOUR KEY> Configure your stripe webhooks here: https://manage.stripe.com/#account/webhooks to http://{YOUR_SERVER}/stripe-webhook
