MB WAY 支払い招待のみ

まず、Stripe アカウントを作成するかサインインします。

アプリケーションから Stripe API にアクセスするには、Stripe の公式ライブラリを使用します。

# Available as a gem
sudo gem install stripe

# If you use bundler, you can add this line to your Gemfile
gem 'stripe'

A PaymentIntent is an object that represents your intent to collect a payment from a customer and tracks the payment process. To create a PaymentIntent that accepts a MB WAY payment method, specify the amount to collect, eur as the currency, and mb_way in the payment_method_types list. If you maintain a list of payment method types that you pass when creating a PaymentIntent, add mb_way to it.

curl https://api.stripe.com/v1/payment_intents \
  -u "
sk_test_BQokikJOvBiI2HlWgH4olfQ2
:" \
  -d amount=1000 \
  -d currency=eur \
  -d "payment_method_types[]"=mb_way

client secret を取得する

PaymentIntent には、client secret が含まれています。これは、支払いプロセスを安全に完了するためにクライアント側で使用されます。client secret をクライアント側に渡す際は、いくつかの方法を使用できます。

get '/secret' do
  intent = # ... Create or retrieve the PaymentIntent
  {client_secret: intent.client_secret}.to_json
end

(async () => {
  const response = await fetch('/secret');
  const {client_secret: clientSecret} = await response.json();
  // Render the form using the clientSecret
})();

When you confirm the payment, pass the client secret.

Use stripe.confirmMbWayPayment to initiate the payment authorization with your customer.

The customer receives a notification about the payment request, and authorizes or declines the request in their MB WAY app.

// Inititates the payment request notification to the customer
stripe.confirmMbWayPayment(
  '{{PAYMENT_INTENT_CLIENT_SECRET}}',
  {
    payment_method: {
      billing_details: {
        // Phone number is required for all MB WAY payment
        phone: '+351911111111'
      }
    }
  }
).then(function(result) {
  if (result.error) {
    // Inform the customer that there was an error.
    console.log(result.error.message);
  }
});

By default, Stripe.js polls for updates to the PaymentIntent. The promise returned by confirmMbWayPayment resolves when the PaymentIntent reaches the succeeded state, or when the payment fails and the PaymentIntent returns to the requires_payment_method state. See the PaymentIntent lifecycle for details on how these transitions happen.

To poll yourself, disable automatic polling by setting handleActions: false:

stripe.confirmMbWayPayment(
  '{{PAYMENT_INTENT_CLIENT_SECRET}}',
  {
    payment_method: {
      billing_details: {
        phone: '+351911111111'
      }
    }
  }
  { handleActions: false } // <---- Like this
)

In this case, call the PaymentIntents API to fetch status of the PaymentIntent yourself.

Test your MB WAY integration by using the following test phone numbers. Each set of details reproduces a common live mode scenario.
