MB WAY Component

Add MB WAY to an existing Components integration

Our Web Component renders MB WAY in your payment form, and presents the waiting screen while the shopper completes the payment in the MB WAY app.

MB WAY is supported as a mature feature as of Component version 3.9.1. For more information, refer to Release notes.

Before you begin

This page explains how to add MB WAY to your existing Web Components integration. The Web Components integration works the same way for all payment methods. If you haven't done this integration yet, refer to our Components integration guide.

Before starting your MB WAY integration:

  1. Make sure that you have set up your back end implementation, and created an instance of AdyenCheckout.
  2. Add MB WAY in your test Customer Area.

Show MB WAY in your payment form

To present the MB WAY Component in your payment form:

  1. Make a POST /paymentMethods request from your server, specifying:

    • countryCode: PT
    • amount.currency: EUR
  2. Pass the full response from the /paymentMethods call as the paymentMethodsResponse object when creating an instance of the AdyenCheckout.
    Make sure your AdyenCheckout configuration has the onAdditionalDetails event handler, which is required for MB WAY.

  3. Add the MB WAY Component:

    a. Create a DOM element for MB WAY, placing it where you want the form to be rendered:

    <div id="mbway-container"></div>

    b. Create an instance of the MB WAY Component, and mount it:

    const mbwayComp = checkout.create('mbway').mount('#mbway-container');

Make a payment

When the shopper selects to pay, the Component calls the onChange event, which contains a

  1. If state.isValid is true, collect the and pass this to your server.

  2. From your server, make a /payments request, including:

    • paymentMethod: The from the onChange event from your front end.
    curl \
    -H "x-API-key: YOUR_X-API-KEY" \
    -H "content-type: application/json" \
    -d '{
      "amount": {
        "currency": "EUR",
        "value": 1000
      "merchantAccount": "YOUR_MERCHANT_ACCOUNT",
      "paymentMethod": {
        "type": "mbway",
        "shopperEmail": "",
        "telephoneNumber": "+351213822199"
      "reference": "YOUR_ORDER_NUMBER",
      "shopperStatement": "MBWay shopper statement"

    The /payments response contains:

    • resultCode: Pending, means the shopper needs to complete the payment in their MB WAY app.
    • action: use this object in the next step to display the waiting screen while the shopper completes the payment in their MB WAY app.
    /payments response
    "resultCode": "Pending",
    "action": {
      "paymentData": "Ab02b4c0!BQABAgCX79JLFTqePTGTb...",
      "paymentMethodType": "mbway",
      "type": "await"
    "paymentData": "Ab02b4c0!BQABAgCX79JLFTqePTGTb..."

Show the waiting screen

Pass the action from your /payments response to your front end:


The Component uses handleAction(action)to show the waiting screen on your frontend for 15 minutes. During this time, the shopper uses their MB WAY app to complete the payment.

In the background, the Component checks the status of the payment and calls:

  • onAdditionalDetails if the shopper successfully completes the payment.
  • onError if the payment not successful or the shopper does not complete the payment in 15 minutes.

Check the payment result

To check the payment result, use the object from the corresponding event handler:

  • onAdditionalDetailsfor successful payments.
  • onError for unsuccessful or timed out payments.

From your server, make a POST /payments/details request with:

  • details: the from the onAdditionalDetails or onError event.
  • paymentData: the from the onAdditionalDetails or onError event.
/payments/details request
  "{ from onAdditionalDetails or onError}details{/hint}": {
    "payload": "Ab02b4c0!BQABAgDniIvNLMYAVGjHw..."
  "{ from onAdditionalDetails or on Error}paymentData{/hint}": "Ab02b4c0!BQABAgCX79JLFTqePTGTb..."

You receive a response containing:

  • additionalData: Object containing the value and currency for the payment.
  • pspReference: Our unique identifier for the transaction.
  • resultCode: Authorised for successful payments or Refused for unsuccessful or timed out payments. Use this to present the payment result to your shopper.
