BasicCardRequest

The BasicCardRequest dictionary is a JavaScript object-structure that can be used in the Payment Request API. The properties of BasicCardRequest are defined in the Basic Card Payment spec).

Properties

BasicCardRequest.supportedNetworks Optional Secure context

An optional array of DOMStrings representing the card networks that the retailer supports (e.g. "amex", "mastercard"); see Card network identifiers for a complete list. If the property is missing, it implies that all networks are supported.

Obsolete properties

These properties have been removed from the Payment Method: Basic Card specification and should no longer be used.

BasicCardRequest.supportedTypes Optional Secure context

This obsolete property was used to provide an optional array of DOMStrings representing the card types that the retailer supports (e.g. credit, debit, prepaid). If the property is missing, it implies that all the card types are supported. Instead of using this property, it is up to the server to check support for the card given the information coded into the account number.

Card network identifiers

The W3C maintains an official list of approved card network identifier strings, which may be used in the supportedNetworks list. Those are:

Examples

In the following example, the PaymentRequest() constructor is used to create a new payment request, which takes three objects as parameters — one containing details of the payment methods that can be used for the payment, one containing details of the actual order (such as items bought and shipping options), and an optional object that describes what data is needed to fullfil the payment (e.g., a shipping address).

The first of these three (supportedInstruments in the example below) contains a data property that has to conform to the structure defined by the BasicCardRequest dictionary.

var supportedInstruments = [{
  supportedMethods: 'basic-card',
  data: {
    supportedNetworks: ['visa', 'mastercard', 'amex', 'jcb',
                        'diners', 'discover', 'mir', 'unionpay']
  }
}];

var details = {
  total: {label: 'Donation', amount: {currency: 'USD', value: '65.00'}},
  displayItems: [
    {
      label: 'Original donation amount',
      amount: {currency: 'USD', value: '65.00'}
    }
  ],
  shippingOptions: [
    {
      id: 'standard',
      label: 'Standard shipping',
      amount: {currency: 'USD', value: '0.00'},
      selected: true
    }
  ]
};

var options = {requestShipping: true};

try {
  var request = new PaymentRequest(supportedInstruments, details, options);
  // Add event listeners here.
  // Call show() to trigger the browser's payment flow.
  request.show().then(function(instrumentResponse) {
    // Do something with the response from the UI.
  })
  .catch(function(err) {
    // Do something with the error from request.show().
  });
} catch (e) {
  // Catch any other errors.
}

Once the payment flow has been triggered using PaymentRequest.show() and the promise resolves successfully, the PaymentResponse object available inside the fulfilled promise (instrumentResponse above) will have a PaymentResponse.details property that will contain response details. This has to conform to the structure defined by the BasicCardResponse dictionary, and may look something like this:

{
  "cardNumber' : '9999999999999999",
  "cardholderName' : 'Mr Dick Straw",
  "cardSecurityCode" : "999",
  "expiryMonth" : "07",
  "expiryYear" : "2021",
  "billingAddress" : {
    "country" : "GB",
    // etc. billing address is a PaymentAddress object
  }
}
