TWINT Component

Add TWINT to an existing Components integration.

Our TWINT Component renders TWINT in your payment form. When making a TWINT payment, you additionally need to use createFromAction to redirect the shopper to Twint.

Before you begin

This page explains how to add TWINT 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 TWINT integration:

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

Show TWINT in your payment form

To present the TWINT Component in your payment form:

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

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

  3. Add the TWINT Component:
    a. Create a DOM element for TWINT, placing it where you want the form to be rendered:
    <div id="twint-container"></div>

    b. Create and mount an instance of the TWINT Component using its component name, twint. 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 twintComponent =  checkout.create('twint', {
        onSubmit: handleOnSubmit // Optional, only if you want to override the onSubmit defined in your AdyenCheckout instance
    }).mount('#twint-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

When a shopper chooses to pay with TWINT, the Component redirects them to the TWINT webpage. Depending on how they are accessing your site:

  • For shoppers on mobile, the TWINT webpage offers to open the TWINT app or copy the short code.
  • For shoppers on desktop or laptop, the TWINT webpage offers to scan the QR code with their TWINT app or copy the short code.
  1. 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. Make sure that the returnUrl uses HTTPS.

Here is how you would make a payment request for TWINT for 10 CHF.

curl https://checkout-test.adyen.com/v67/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": "CHF",
        "value": 1000
    },
    "countryCode": "CH",
    "returnUrl": "https://your-company.com/checkout?shopperOrder=12xy..",
    "paymentMethod": {
        "type": "twint"
    }
}'
# 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 => "CHF",
    :value => 1000
  },
  :reference => "YOUR_ORDER_NUMBER",
  :paymentMethod => {
    :type => "twint"
  },
  :countryCode => "CH",
  :merchantAccount => "YOUR_MERCHANT_ACCOUNT",
  :returnUrl => "https://your-company.com/checkout?shopperOrder=12xy.."
})
// 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("CHF");
    amount.setValue(1000L);
    paymentsRequest.setAmount(amount);

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

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

    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" => "CHF",
    "value" => 1000
  ),
  "reference" => "YOUR_ORDER_NUMBER",
  "paymentMethod" => array(
    "type" => "twint"
  ),
  "countryCode" => "CH",
  "merchantAccount" => "YOUR_MERCHANT_ACCOUNT",
  "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': 'CHF'
   },
   'reference': 'YOUR_ORDER_NUMBER',
   'paymentMethod': {
      'type': 'twint'
   },
   'countryCode': 'CH',
   'merchantAccount': 'YOUR_MERCHANT_ACCOUNT',
   'returnUrl': 'https://your-company.com/checkout?shopperOrder=12xy..'
})
// 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("CHF", 1000);
var details = new Model.Checkout.DefaultPaymentMethodDetails{
  Type = "twint"
};
var paymentRequest = new Adyen.Model.Checkout.PaymentRequest
{
  Reference = "YOUR_ORDER_NUMBER",
  Amount = amount,
  CountryCode = "CH",
  MerchantAccount = "YOUR_MERCHANT_ACCOUNT",
  PaymentMethod = details,
  ReturnUrl = "https://your-company.com/checkout?shopperOrder=12xy.."
};

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: "CHF", value: 1000 },
    paymentMethod: {
        type: 'twint'
    },
    reference: "YOUR_ORDER_NUMBER",
    merchantAccount: config.merchantAccount,
    countryCode: "CH",
    returnUrl: "https://your-company.com/checkout?shopperOrder=12xy.."
}).then(res => res);

The /payments response contains an action object with the information needed to redirect the shopper.

/payments response
{
   "resultCode":"RedirectShopper",
   "action":{
      "paymentMethodType":"twint",
      "method":"GET",
      "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
      "type":"redirect"
   }
}

If your integration is set up correctly, the action object is passed from your server to the client.

Handle the redirect result

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 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:
    • details: Object that contains the URL-decoded redirectResult returned when the shopper was redirected back to your site.
    /payments/details request
    curl https://checkout-test.adyen.com/v67/payments/details \
    -H "x-API-key: YOUR_X-API-KEY" \
    -H "content-type: application/json" \
    -d '{
       "details": {
         "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
     }
    }'
    The /payments/details response contains:
    • resultCode: Use this to present the payment result to your shopper.
    • pspReference: Our unique identifier for the transaction.
    /payments/details response
    {
        "resultCode": "Authorised",
        "pspReference": "88154795347618C"
    }

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

You will also receive the outcome of the payment asynchronously in a notification webhook.

The resultCode values you can receive for TWINT are:

resultCode Description Action to take
Authorised The shopper completed their payment, and it has been sent to the bank for processing. In most cases, this means that you will receive the funds. If you are using manual capture, you also need to capture the payment. Inform the shopper that the payment has been successful.
Cancelled The shopper cancelled the payment while on their bank's website. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error There was an error when the payment was being processed. Inform the shopper that there was an error processing their payment. The response contains a refusalReason, indicating the cause of the error.
Pending or
Received
The shopper has completed the payment but the final result is not yet known. Inform the shopper that you've received their order, and are waiting for the payment to be completed.
You will receive the final result of the payment in an AUTHORISATION notification.
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 failed to return to your website or app, wait for notification webhooks to know the outcome of the payment. The notification webhooks you can receive for TWINT are:

eventCode success field Description Action to take
AUTHORISATION false The transaction failed. Cancel the order and inform the shopper that the payment failed.
AUTHORISATION true The shopper successfully completed the payment. Inform the shopper that the payment has been successful and proceed with the order.

Capture the payment

By default, TWINT payments are captured automatically. This means that the Capture Delay setting in your Customer Area is set to Immediate or 1–7 days.
In case the Capture Delay setting is set to Manual, then you need to manually capture the payment.

Partial capture

To partially capture a TWINT payment, specify in your /payments/{paymentPspReference}/captures request:

  • modificationAmount: The amount that the shopper should pay.

The following example shows how to make a partial capture request:

/capture request
{
   "originalReference":"PSP_REFERENCE",
   "merchantAccount":"YOUR_MERCHANT_ACCOUNT",
   "modificationAmount":{
      "currency":"CHF",
      "value":"700"
   },
   "reference":"YOUR_CAPTURE_REFERENCE"
}

Any unclaimed amount that is left over after partially capturing a payment is automatically cancelled.

TWINT doesn't support multiple partial captures.

Test and go live

Check the status of TWINT test payments in your Customer Area > Transactions > Payments.
Before you can accept live TWINT payments, you need to submit a request for TWINT in your live Customer Area.
