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:
- Make sure that you have set up your back end implementation, and created an instance of
AdyenCheckout
. -
Add MoMo ATM in your Customer Area.
Show MoMo ATM in your payment form
To present the MoMo ATM Component in your payment form:
-
From your server, make a POST /paymentMethods request specifying:
- countryCode: VN
- amount.currency: VND
- amount.value: The value of the payment.
-
Pass the full response from the /paymentMethods call as the
paymentMethodsResponse
object when creating an instance of theAdyenCheckout
. - 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 astate.data
object including the shopper's selected payment method. If your integration is set up correctly, thestate.data
is passed on to your server.
Make a payment
From your server, make a POST /payments request, specifying:
paymentMethod
: Thestate.data.paymentMethod
from theonSubmit
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://
orhttps://
. 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/v66/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({

: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..",

);
$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{

};
var paymentsRequest = new Model.Checkout.PaymentRequest
{

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:
-
action.method
: GET. The HTTP request method that you should use. After the shopper completes the payment, they will be redirected back to yourreturnURL
using the same method.
{
"resultCode":"RedirectShopper",
"action":{
"method":"GET",
"paymentData":"Ab02b4c0!BQABAgCSZT7t...",
"paymentMethodType":"momo_atm",
"type":"redirect",
"url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=..."
},
"details":[
{
"key":"redirectResult",
"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:
-
Call
createFromAction
, passing theaction
object from the previous step. This will return a new Component that you need to mount:
The Component redirects the shopper to MoMo ATM to complete the payment.checkout.createFromAction(action).mount('#my-container');
- After the shopper is redirected back to your website, URL-decode the
redirectResult
that was appended to yourreturnUrl
when the shopper was redirected back to your site, and pass it to your back end. -
Check the payment result by making a POST /payments/details request, specifying:
-
paymentData
: The value you received in the /payments response. -
details
: Object that contains the URL-decoded values of the parameters that were appended to thereturnUrl
when the shopper was redirected back to your site.
-
resultCode
: Use this to present the payment result to your shopper. -
pspReference
: Our unique identifier for the transaction.
-
Present the payment result
Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.
The resultCode
values you can receive for MoMo ATM are:
resultCode | Description | Action to take |
---|---|---|
Authorised | The payment was successful. | Inform the shopper that the payment has been successful. |

Refused | The payment was refused by the shopper's bank. | Ask the shopper to try the payment again using a different payment method. |
If the shopper closed the browser and failed to return to your website, wait for notification webhooks to know the outcome of the payment. The notification webhooks you can receive for MoMo ATM are:
eventCode | success field | Description | Action to take |
---|---|---|---|
AUTHORISATION | false | The transaction failed. | Cancel the order and inform the shopper that the payment failed. |
