Before you use the Google Wallet API for an integration, complete first four steps from this guide.

On 3rd step you are going to obtain **key.json, which will be needed for the gem initialization.

# config/initializers/google_wallet.rb

GoogleWallet.configure do |config|
  config.load_credentials_from_file('./key.json')
  config.issuer_id = '33880000000XXXXXXXX'
  config.debug_mode = true
  config.logger = Logger.new(STDOUT)
end

}

# Create Resource of EventTicket Object
ticket = GoogleWallet::Resources::EventTicket::Object.new(attributes: ticket_attributes)

# Push Object to Google Wallet API

# separated push and sign
ticket.push
jwt = ticket.sign(push_resource: false)

# or combined - just use sign
jwt = ticket.sign # default, push_resource: true

"https://pay.google.com/gp/v/save/#{jwt}"
