Build Status


Monza is a ruby gem that makes In-App Purchase receipt and Auto-Renewable subscription validation easy.

You should always validate receipts on the server, in Apple's words:

Use a trusted server to communicate with the App Store. Using your own server lets you design your app to recognize and trust only your server, and lets you ensure that your server connects with the App Store server. It is not possible to build a trusted connection between a user’s device and the App Store directly because you don’t control either end of that connection.


Add this line to your application's Gemfile:

gem 'monza'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install monza


Basic Usage:
data = "base64 receipt data string"
options = { shared_secret: "your shared secret" }
response = Monza::Receipt.verify(data, options)

You can also pass in

with value
as an option in the options hash for iOS7 style app receipts.
