Make It Rain

Credits to @fitztrev for an excellent idea! Check the original PHP/Slack/Stripe version https://github.com/fitztrev/make-it-rain. This is a weekend rewrite using Ruby, plain old Rack and Docker. Get a random "make it rain" gif posted to a Slack channel every time you get paid through Braintree or Chargebee!

How to use

1. Check out the Docker image: https://hub.docker.com/r/mrgrodo/make-it-rain-rb/

2. Create a "Successful Charge" webhook in Braintree or a general purpose Chargebee webhook in your webhook settings. Make sure to point the webhook to an instance of this service with a correct secret parameter: https://my-make-it-rain-instance.com/?secret=your-mkr-app-secret.

3. Provide environment variables to the container and a Slack access token - environment.rb loads them all.

# pass this to *every* webhook as a GET param: "?secret=<MKR_APP_SECRET>"
MKR_APP_SECRET = ENV.fetch('MKR_APP_SECRET')

# incoming webhook URL for Slack
MKR_SLACK_WEBHOOK_URL = ENV.fetch('MKR_SLACK_WEBHOOK_URL')

# Braintree config
Braintree::Configuration.environment = ENV['BT_ENV']
Braintree::Configuration.merchant_id = ENV['BT_MERCHANT_ID']
Braintree::Configuration.public_key = ENV['BT_PUBLIC_KEY']
Braintree::Configuration.private_key = ENV['BT_PRIVATE_KEY']

4. Run the container - check out run.sh for development and as an example for your deployment.
