IappValidator

IappValidator is a Ruby gem that facilitates purchase verification for Google Play. It leverages the Google Play Developer API to confirm whether a purchase is valid or not.

Add the gem to your application's Gemfile:

gem 'iapp_validator'

Then run:

bundle install

To verify Google Play purchases, you need a Google Play Service Account JSON key.

1. Go to Google Cloud Console.
2. Create a Service Account and grant it "Android Publisher" permissions.
3. Download the JSON key file.
4. Place it in your app (e.g., config/credentials/google_play_service_account.json).

require 'iapp_validator'

validator = ReceiptHelper::GooglePlayValidator.new
result = validator.verify_purchase("com.package.name", "your.product.id", "purchase_token")

if result[:success]
  puts "Purchase is valid"
else
  puts "Purchase failed: #{result[:error]}"
end

• package_name: The package name of your app on Google Play (e.g., com.katkatgames.kanbiztoupatou)
• product_id: The ID of the purchased product (e.g., coins_100)
• token: The purchase token returned from the Google Play API.

To install the gem locally:

bundle exec rake install

To open an interactive console:

bin/console
