require 'stripe'

Stripe::api_key = ENV['STRIPE_SECRET_KEY']

customer = Stripe::Customer.create

puts customer.id

100.times do |i|
  payment_method = Stripe::PaymentMethod.create(type: 'card', card: { number: '4242424242424242', exp_year: 2030, exp_month: 01})
  Stripe::PaymentMethod.attach(payment_method.id, customer: customer.id)

  puts payment_method.id
end

Stripe::PaymentMethod.list(customer: customer.id, type: "card")
