Vietnamese online banking Component

Our MoMo ATM Component renders MoMo ATM in your payment form. As with other redirect payment methods, you need to use createFromAction to redirect the shopper, and handle the redirect after the shopper returns to your website.

Before you begin

This page explains how to add MoMo ATM 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 MoMo ATM integration:

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

Show MoMo ATM in your payment form

To present the MoMo ATM Component in your payment form:

1. From your server, make a POST /paymentMethods request specifying:

   • countryCode: VN
   • amount.currency: VND
   • amount.value: The value of the payment.

2. Pass the full response from the /paymentMethods call as the paymentMethodsResponse object when creating an instance of the AdyenCheckout.

3. Add the MoMo ATM Component:
   a. Create a DOM element for MoMo ATM, placing it where you want the form to be rendered:

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

   b. Create and mount an instance of the MoMo ATM Component using its component name, momo_atm. This renders a button on your payment form.

   function handleOnSubmit(state, component) {
       // Optional, only if you want to override the onSubmit defined in your AdyenCheckout instance
       state.isValid // True or false. Specifies if all the information that the shopper provided is valid.
       state.data // Provides the data that you need to pass in the `/payments` call.
       component // Provides the active component instance that called this event.
   }
   const momoATMComponent =  checkout.create('momo_atm', {
       onSubmit: handleOnSubmit // Optional, only if you want to override the onSubmit defined in your AdyenCheckout instance
   }).mount('#momoATM-container');

   When the shopper selects the payment method, the Component calls the onSubmit event, which contains a state.data object including the shopper's selected payment method. If your integration is set up correctly, the state.data is passed on to your server.

Make a payment

From your server, make a POST /payments request, specifying:

• paymentMethod: The state.data.paymentMethod from the onSubmit event from your front end.
• returnUrl: The URL where the shopper will be redirected back to after completing the payment. The URL should include the protocol: http:// or https://. For example, https://your-company.com/checkout/. You can also include your own additional query parameters, for example, shopper ID or order reference number.

Here is how you would make a payment request for 1000 VND.

curl https://checkout-test.adyen.com/v64/payments \
-H "x-API-key: YOUR_X-API-KEY" \
-H "content-type: application/json" \
-d '{
  "merchantAccount":"YOUR_MERCHANT_ACCOUNT",
  "reference":"YOUR_ORDER_NUMBER",
  "amount":{
    "currency":"VND",
    "value":1000
  },
  "{hint:state.data.paymentMethod from onSubmit}paymentMethod{/hint}":{
    "type":"momo_atm"
  },
  "returnUrl":"https://your-company.com/checkout?shopperOrder=12xy.."
}'

# Set your X-API-KEY with the API key from the Customer Area.
adyen = Adyen::Client.new
adyen.api_key = "YOUR_X-API-KEY"
 
response = adyen.checkout.payments({
  :amount => {
    :currency => "VND",
    :value => 1000
  },
  :reference => "YOUR_ORDER_NUMBER",
  :paymentMethod => {
    :type => "momo_atm"
  },
  :returnUrl => "https://your-company.com/checkout?shopperOrder=12xy..",
  :merchantAccount => "YOUR_MERCHANT_ACCOUNT"
})

// Set YOUR_X-API-KEY with the API key from the Customer Area.
// Change to Environment.LIVE and add the Live URL prefix when you're ready to accept live payments.
    Client client = new Client("YOUR_X-API-KEY", Environment.TEST);
    Checkout checkout = new Checkout(client);

    PaymentsRequest paymentsRequest = new PaymentsRequest();

    String merchantAccount = "YOUR_MERCHANT_ACCOUNT";
    paymentsRequest.setMerchantAccount(merchantAccount);

    Amount amount = new Amount();
    amount.setCurrency("VND");
    amount.setValue(15000L);
    paymentsRequest.setAmount(amount);

    DefaultPaymentMethodDetails paymentMethodDetails = new DefaultPaymentMethodDetails();
    paymentMethodDetails.setType("momo_atm");
    paymentsRequest.setPaymentMethod(paymentMethodDetails);

    paymentsRequest.setReference("YOUR_ORDER_NUMBER");
    paymentsRequest.setReturnUrl("https://your-company.com/checkout?shopperOrder=12xy..");

    PaymentsResponse paymentsResponse = checkout.payments(paymentsRequest);

// Set your X-API-KEY with the API key from the Customer Area.
$client = new \Adyen\Client();
$client->setXApiKey("YOUR_X-API-KEY");
$service = new \Adyen\Service\Checkout($client);

$params = array(
  "amount" => array(
    "currency" => "VND",
    "value" => 1000
  ),
  "reference" => "YOUR_ORDER_NUMBER",
  "paymentMethod" => array(
    "type" => "momo_atm"
  ),
  "returnUrl" => "https://your-company.com/checkout?shopperOrder=12xy..",
  "merchantAccount" => "YOUR_MERCHANT_ACCOUNT"
);
$result = $service->payments($params);

#Set your X-API-KEY with the API key from the Customer Area.
adyen = Adyen.Adyen()
adyen.client.xapikey = 'YOUR_X-API-KEY'

result = adyen.checkout.payments({
   'amount': {
      'value': 1000,
      'currency': 'VND'
   },
   'reference': 'YOUR_ORDER_NUMBER',
   'paymentMethod': {
      'type': 'momo_atm'
   },
   'returnUrl': 'https://your-company.com/checkout?shopperOrder=12xy..',
   'merchantAccount': 'YOUR_MERCHANT_ACCOUNT'
})

// Set your X-API-KEY with the API key from the Customer Area.
var client = new Client ("YOUR_X-API-KEY", Environment.Test);
var checkout = new Checkout(client);

var amount = new Model.Checkout.Amount("VND", 1000);
var details = new Model.Checkout.DefaultPaymentMethodDetails{
  Type = "momo_atm"
};
var paymentsRequest = new Model.Checkout.PaymentRequest
{
  Reference = "YOUR_ORDER_NUMBER",
  Amount = amount,
  ReturnUrl = @"https://your-company.com/checkout?shopperOrder=12xy..",
  MerchantAccount = "YOUR_MERCHANT_ACCOUNT",
  PaymentMethod = details
};

var paymentResponse = checkout.Payments(paymentsRequest);

// Set your X-API-KEY with the API key from the Customer Area.
const {Client, Config, CheckoutAPI} = require('@adyen/api-library');
const config = new Config();
// Set your X-API-KEY with the API key from the Customer Area.
config.apiKey = '[API_KEY]';
config.merchantAccount = '[YOUR_MERCHANT_ACCOUNT]';
const client = new Client({ config });
client.setEnvironment("TEST");
const checkout = new CheckoutAPI(client);
checkout.payments({
    amount: { currency: "VND", value: 1000 },
    paymentMethod: {
        type: 'momo_atm'
    },
    reference: "YOUR_ORDER_NUMBER",
    merchantAccount: config.merchantAccount,
    returnUrl: "https://your-company.com/checkout?shopperOrder=12xy.."
}).then(res => res);

The /payments response contains an action object with type:redirect.

{
  "resultCode": "RedirectShopper",
  "action": {
    "method": "GET",
    "paymentData": "Ab02b4c0!BQABAgCSZT7t...",
    "paymentMethodType": "momo_atm",
    "type": "redirect",
    "url": "https://test.adyen.com/hpp/redirect.shtml?brandCode=.."
  },
  "details": [
    {
      "key": "payload",
      "type": "text"
    }
  ],
...
}

If your integration is set up correctly, the action object is passed from your server to the client, and the action.paymentData temporarily stored on your server.

Handle the redirect

Handling the redirect works the same way for all redirect payment methods:

1. Call createFromAction, passing the action object from the previous step. This will return a new Component that you need to mount:

   checkout.createFromAction(action).mount('#my-container');

   The Component redirects the shopper to MoMo ATM to complete the payment.
2. After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
   • paymentData: The value from the /payments response.
   • details: Object that contains the URL-decoded values of the parameters that were returned when the shopper was redirected back to your site. For example, payload or redirectResult.
   The parameters can vary based on the payment method configuration. To check which parameters you should submit, always check the details array from the /payments response.

   /payments/details request

   {
         "paymentData":"Ab02b4c0!BQABAgCJN1wRZuGJmq8dMncmypvknj9s7l5Tj...",
         "details":{
           "{hint:Verify the parameters from /payments response}payload{/hint}":"Ab02b4c0!BQABAgCW5sxB4e/=="
         }
   }

   The /payments/details response contains:
   • resultCode: Use this to present the payment result to your shopper.
   • pspReference: Our unique identifier for the transaction.
