Example Terminal Backend

This is a simple Sinatra webapp that you can use to run the Stripe Terminal example apps. To get started, you can choose from the following options:

1. Run it on a free Render account
2. Run it on Heroku
3. Run it locally on your machine
4. Run it locally via Docker CLI

ℹ️ You also need to obtain your Stripe secret, test mode API Key, available in the Dashboard. Note that you must use your secret key, not your publishable key, to set up the backend. For more information on the differences between secret and publishable keys, see API Keys. For more information on test mode, see Test and live modes.

STRIPE_TEST_SECRET_KEY={YOUR_API_KEY}

2. In your terminal, run bundle install
3. Run ruby web.rb

Running locally with Docker

We have a pre-built Docker image you can run locally if you're into the convenience of containers.

Install Docker Desktop if you don't already have it. Then follow the steps below:

1. In your terminal, run docker run -e STRIPE_TEST_SECRET_KEY={YOUR_API_KEY} -p 4567:4567 stripe/example-terminal-backend (replace {YOUR_API_KEY} with your own test key)
2. The example backend should now be running at http://localhost:4567
