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.

📦 Installation

Add the gem to your application's Gemfile:

gem 'iapp_validator'

Then run:

bundle install

🔐 Configuration

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).

🚀 Usage

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
