ThreeDSecure

ThreeDSecure

This class represents a ThreeDSecure component produced by braintree.threeDSecure.create. Instances of this class have a method for launching a 3D Secure authentication flow.

Constructor

new ThreeDSecure(options)

Do not use this constructor directly. Use braintree.threeDSecure.create instead.

Parameters:
Name Type Description
options object

3D Secure create options
Source:

Methods

cancelVerifyCard(callbackopt) → {Promise|void}

Cancel the 3DS flow and return the verification payload if available.

Parameters:
Name Type Attributes Description
callback callback <optional>

The second argument is a verifyPayload. If there is no verifyPayload (the initial lookup did not complete), an error will be returned. If no callback is passed, cancelVerifyCard will return a promise.
Source:
Example
threeDSecure.cancelVerifyCard(function (err, verifyPayload) {
  if (err) {
    // Handle error
    console.log(err.message); // No verification payload available
    return;
  }

  verifyPayload.nonce; // The nonce returned from the 3ds lookup call
  verifyPayload.liabilityShifted; // boolean
  verifyPayload.liabilityShiftPossible; // boolean
});

teardown(callbackopt) → {Promise|void}

Cleanly remove anything set up by create.

Parameters:
Name Type Attributes Description
callback callback <optional>

Called on completion. If no callback is passed, teardown will return a promise.
Source:
Examples
threeDSecure.teardown();

With callback 

threeDSecure.teardown(function () {
  // teardown is complete
});

verifyCard(options, callbackopt) → {Promise|void}

Launch the 3D Secure login flow, returning a nonce payload.

Parameters:
Name Type Attributes Description
options object

Options for card verification.

Properties
Name Type Attributes Default Description
nonce string

A nonce referencing the card to be verified. For example, this can be a nonce that was returned by Hosted Fields.
amount number

The amount of the transaction in the current merchant account's currency. For example, if you are running a transaction of $123.45 US dollars, amount would be 123.45.
addFrame callback

This addFrameCallback will be called when the bank frame needs to be added to your page.
removeFrame callback

This removeFrameCallback will be called when the bank frame needs to be removed from your page.
showLoader boolean <optional>
 true

Whether to show the loader icon while the bank frame is loading.
callback callback <optional>

The second argument, data, is a verifyPayload. If no callback is provided, it will return a promise that resolves verifyPayload.
Source:
Example

Verifying an existing nonce with 3DS 

var my3DSContainer;

threeDSecure.verifyCard({
  nonce: existingNonce,
  amount: 123.45,
  addFrame: function (err, iframe) {
    // Set up your UI and add the iframe.
    my3DSContainer = document.createElement('div');
    my3DSContainer.appendChild(iframe);
    document.body.appendChild(my3DSContainer);
  },
  removeFrame: function () {
    // Remove UI that you added in addFrame.
    document.body.removeChild(my3DSContainer);
  }
}, function (err, payload) {
  if (err) {
    console.error(err);
    return;
  }

  if (payload.liabilityShifted) {
    // Liablity has shifted
    submitNonceToServer(payload.nonce);
  } else if (payload.liabilityShiftPossible) {
    // Liablity may still be shifted
    // Decide if you want to submit the nonce
  } else {
    // Liablity has not shifted and will not shift
    // Decide if you want to submit the nonce
  }
});

Type Definitions

addFrameCallback(erropt, nullable, iframe) → {void}

The callback used for options.addFrame in verifyCard.

Parameters:
Name Type Attributes Description
err BraintreeError <optional>
<nullable>

null or undefined if there was no error.
iframe HTMLIFrameElement

An iframe element containing the bank's authentication page that you must put on your page.
Source:

removeFrameCallback() → {void}

The callback used for options.removeFrame in verifyCard.

Source:

verifyPayload :object

Properties:
Name Type Description
nonce string

The new payment method nonce produced by the 3D Secure lookup. The original nonce passed into verifyCard was consumed. This new nonce should be used to transact on your server.
details object

Properties
Name Type Description
cardType string

Type of card, ex: Visa, MasterCard.
lastFour string

Last four digits of card number.
lastTwo string
