GrabPay Component

Add GrabPay to your Components integration.

Our GrabPay Component renders GrabPay 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 GrabPay 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 GrabPay integration:

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

Show GrabPay in your payment form

To present the GrabPay Component in your payment form:

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

    Country countryCode amount.currency
    Malaysia MY MYR
    Philippines PH PHP
    Singapore SG SGD

    The response will contain the GrabPay paymentMethod.type:

    • grabpay_MY if the shopper is in Malaysia and is paying with Malaysian Ringgit.
    • grabpay_PH if the shopper is in the Philippines and is paying with Philippine Peso.
    • grabpay_SG if the shopper is in Singapore and is paying with Singapore Dollars.

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

  2. For this example, we'll use a scenario where the shopper is in Singapore. Add the GrabPay Component:
    a. Create a DOM element for GrabPay, placing it where you want the form to be rendered:
    <div id="grabpay-container"></div>

    b. Create and mount an instance of the GrabPay Component using its component name, grabpay_SG. 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 grabpayComponent =  checkout.create('grabpay_SG', {
        onSubmit: handleOnSubmit // Optional, only if you want to override the onSubmit defined in your AdyenCheckout instance
    }).mount('#grabpay-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 for 10 SGD.

curl https://checkout-test.adyen.com/v64/payments \

// 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("SGD");
    amount.setValue(1000L);
    paymentsRequest.setAmount(amount);

    DefaultPaymentMethodDetails paymentMethodDetails = new DefaultPaymentMethodDetails();
    paymentMethodDetails.setType("grabpay_SG");
    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");

$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': 'SGD'
   },
   'reference': 'YOUR_ORDER_NUMBER',

      'type': 'grabpay_SG'
   },
   '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("SGD", 1000);
var details = new Model.Checkout.DefaultPaymentMethodDetails{
  Type = "grabpay_SG"
};
var paymentRequest = new Adyen.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: "SGD", value: 1000 },
    paymentMethod: {
        type: 'grabpay_SG'
    },
    reference: "YOUR_ORDER_NUMBER",
    merchantAccount: config.merchantAccount,
    returnUrl: "adyencheckout://your.package.name"
}).then(res => res);

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

/payments response
{
    "resultCode": "RedirectShopper",
    "action": {
        "method": "GET",
        "paymentData": "Ab02b4c0!BQABAgBlmvU6H9LnijLzrYAgMfopoX...",
        "paymentMethodType": "grabpay_SG",
        "type": "redirect",
        "url": "https://test.adyen.com/hpp/skipDetails.shtml?brandCode=grabpay_SG&currencyCode=SGD..."
    },
    "details": [
        {
            "key": "payload",
            "type": "text"
        }
    ],
    "paymentData": "Ab02b4c0!BQABAgBlmvU6H9LnijLzrYAgMfopoX...",
    "redirect": {
        "method": "GET",
        "url": "https://test.adyen.com/hpp/skipDetails.shtml?brandCode=grabpay_SG&currencyCode=SGD..."
    }
}

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 GrabPay 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.
    /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.

The resultCode values you can receive for GrabPay are:

resultCode Description Action
Authorised The payment was authorised. You will receive the funds in a number of days. Inform the shopper that the payment was successful.
Cancelled The shopper cancelled the payment before it was completed, for example while in the GrabPay app. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Refused The payment was refused by the shopper's card issuer. Ask the shopper to try the payment again using a different payment method or card.
Pending or
Received
The shopper has completed the payment but the final result is not yet known. You will receive the final result of the payment in an AUTHORISATION notification. Inform the shopper that you've received their order, and are waiting for the payment to be processed.

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 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.
OFFER_CLOSED true The shopper did not complete the payment. Cancel the order and inform the shopper that the payment timed out.

Recurring payments

Recurring payments require approval from GrabPay. For more information about eligibility, contact our Support Team.

To make recurring GrabPay payments:

  1. In your initial payment request, create a shopper token specifying:
    • storePaymentMethod: true
    • shopperReference: Your unique identifier for the shopper.
    • shopperInteraction: Ecommerce
  2. When you make a /payments/details request after the shopper is redirected back to your website or app, save the recurringDetailReference that you receive in the additionalData of the response. This is your token.
  3. Make subsequent recurring transactions specifying a paymentMethod with:
    • type: The GrabPay type, for example grabpay_SG.
    • recurringDetailReference: The token you received in the /payments/details response.

Refer to Tokenization for more information and detailed instructions.

Test and go live

To test your GrabPay integration:

  1. Contact our Support Team to register for a GrabPay test wallet. You'll need to fill out a form and provide a phone number (local or international) and an email address. Note that the wallet will have a balance limit depending on the wallet regulations in each market.
  2. In the simulator, log in to Grab with the phone number you registered, and specify the one-time password you receive on that phone number.

Check the status of the GrabPay test payments in your Customer Area > Transactions > Payments.

Before you can accept live GrabPay payments, you need to submit a request for GrabPay in your live Customer Area.
