GrabPay Component

Add GrabPay to an existing Components integration.

Our GrabPay Component renders GrabPay in your payment form. When making a GrabPay payment, you additionally need to use createFromAction to handle the redirect to GrabPay, and back 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:

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

Show GrabPay in your payment form

To show GrabPay Component in your payment form, you need to:

Specify in your /paymentMethods request:

Country countryCode amount.currency

Malaysia MY MYR

Philippines PH PHP

Singapore SG SGD

Thailand TH THB

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.
- grabpay_TH if the shopper is in Thailand and is paying with Thai Baht.
Pass the full response to the paymentMethodsResponse object when creating an instance of the AdyenCheckout.
Add the GrabPay Component:
1. Create a DOM element for GrabPay, placing it where you want the form to be rendered:
```
<div id="grabpay-container"></div>
```
2. Create an instance of the GrabPay Component, specifying its paymentMethod.type, and mount it. This renders a button on your payment form.
```
const grabpay = checkout.create('grabpay_SG').mount('#grabpay-container');
```

Make a payment

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

If state.isValid is true, collect the state.data and pass this to your server.
From your server, make a /payments, specifying:
- paymentMethod: The state.data.paymentMethod from the onChange event from your front end.
- reference: Your unique reference for this payment.
- amount: The amount that the shopper needs to pay.
- returnUrl: The URL the shopper will be redirected back to after they complete the payment.

The /payments response contains:

action: Object containing information about the redirect.
action.paymentData: Store this on your server — you need to submit this in your /payments/details request when handling the redirect.
action.method: GET or POST. The HTTP request method that you should use. After the shopper completes the payment, they will be redirected back to your returnURL using the same method.
The redirect method depends on your payment method configuration and the length of the data included in the request, so make sure that your integration can handle both HTTP GET and HTTP POST methods.

/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",

    ],
    "paymentData": "Ab02b4c0!BQABAgBlmvU6H9LnijLzrYAgMfopoX...",

        "url": "https://test.adyen.com/hpp/skipDetails.shtml?brandCode=grabpay_SG&currencyCode=SGD..."
    }
}

Pass the action object to your front end.

Handle the redirect result

Call createFromAction and pass 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.
After the shopper is redirected back to your website, check the payment result by making a /payments/details request, specifying:
- paymentData: Value you received in 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. To check the parameters that you should submit, refer to the details.key returned in the /payments response.
https://docs.adyen.com/payment-methods/online-banking-india/web-component#-payments-details-request
- /payments/details request
{ "paymentData":"Ab02b4c0!BQABAgCJN1wRZuGJmq8dMncmypvknj9s7l5Tj...", "details":{ "{hint:Verify the parameters from /payments response}payload{/hint}":"Ab02b4c0!BQABAgCW5sxB4e/==" } }
You receive a response containing:
- resultCode: Use this to present the result to your shopper.
- pspReference: Our unique identifier for the transaction.
https://docs.adyen.com/payment-methods/online-banking-india/web-component#-payments-details-response
- /payments/details response
{ "resultCode": "Authorised", "pspReference": "88154795347618C" }

For more information and detailed instructions, refer to Handling the redirect result.

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	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.
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 processed.

If a shopper completed the payment but failed to return to your website or app, you will receive the outcome of the payment in an AUTHORISATION notification.

Recurring payments

To make recurring GrabPay payments:

In your initial payment request, create a shopper token specifying:
- storePaymentMethod: true
- shopperReference: Your unique identifier for the shopper.
- shopperInteraction: Ecommerce
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.
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:

Contact Grab and register a local phone number and an email address with them for GrabPay. The local phone number needs to be in the country that you want to test GrabPay payments for. For example, to test grabpay_SG you need a Singapore phone number.
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.
