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:
- Make sure that you have set up your back end implementation, and created an instance of
AdyenCheckout
. -
Add GrabPay in your Customer Area.
Show GrabPay in your payment form
To present the GrabPay Component in your payment form:
-
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.
-
Pass the full response from the /paymentMethods call as the
paymentMethodsResponse
object when creating an instance of theAdyenCheckout
. - 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 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 for 10 SGD.
curl https://checkout-test.adyen.com/v66/payments \
-H "x-API-key: YOUR_X-API-KEY" \
-H "content-type: application/json" \

},

# 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);

String merchantAccount = "YOUR_MERCHANT_ACCOUNT";

},

merchantAccount: config.merchantAccount,
returnUrl: "adyencheckout://your.package.name"
}).then(res => res);
The /payments response contains an action
object with type
:redirect.
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":"grabpay_SG",
"type":"redirect",
"url":"https://test.adyen.com/hpp/skipDetails.shtml?brandCode=grabpay_SG..."
},
"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 GrabPay to complete the payment.checkout.createFromAction(action).mount('#my-container');
-
After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
-
paymentData
: The value your 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.
-
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 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
To make recurring GrabPay payments:
-
In your initial payment request, create a shopper token specifying:
-
storePaymentMethod
: true -
shopperReference
: Your unique identifier for the shopper (minimum length three characters). -
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 theadditionalData
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 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.
- 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.
