Generate and send invoices from Stripe webhooks in Ruby with the Invoice Generator API.
This simple Stripe webhook was built using Sinatra. It emails an invoice to your customer whenever the invoice.created webhook is received from Stripe. It uses the invoice-generator.com API to produce the PDF.
Enter your company details into webhook.rb. Then you can host this app somewhere like Heroku and add a Stripe webhook for https://example.com/_billing_events.
