Monza is a ruby gem that makes App Store in app purchase receipt validation and auto-renewable subscription validation easy.
You should always validate receipts on the server, in [Apple's words] (https://developer.apple.com/library/ios/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html#//apple_ref/doc/uid/TP40010573-CH104-SW1):
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)
# Check if subscription is active
# this checks if latest transaction receipt expiry_date is in today or the future
response.is_subscription_active? # => true or false
# Check most recent expiry date
response.latest_expiry_date # => DateTime
# Receipt object
# See Receipt class
response.receipt
# Receipt In App Transactions
# Returns array of TransactionReceipt objects, see TransactionReceipt class
response.receipt.in_app
# Receipt Latest Transactions List, use these instead if in_app to ensure you always have the latest
# Returns array of TransactionReceipt objects, see TransactionReceipt class
response.latest_receipt_info
# Latest receipt base64 string
response.latest_receipt
