Requirements

Requirement	Description
Integration type	Make sure that you have an existing Advanced flow Android Components integration.
Setup steps	Before you begin, add GrabPay in your 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/region countryCode amount.currency

Malaysia MY MYR

Singapore SG SGD

Philippines ¹ PH PHP

¹ GrabPay PayLater is not available in Philippines.

Deserialize the response from the /paymentMethods call and get the object with type grabpay_XX, where XX is the country code.

Collect additional information in your payment form

Collecting additional information is only needed for GrabPay PayLater payments. However, we highly recommend collecting this information in your initial integration for GrabPay Wallet because it will help save development resources if you plan to enable GrabPay PayLater afterwards.

Collect the following details from the shopper:

deliveryAddress: The address where the purchased goods should be delivered, including the country, city, street, house number, and postal code.
lineItems: Price and product information about the purchased items, to be included on the invoice sent to the shopper.

Pass the collected data to your server because you will need it when making a payment. This information will be used by GrabPay to perform risk checks.

Make a payment

When the shopper proceeds to pay, the Component returns the paymentComponentState.data.paymentMethod. Depending on the type of GrabPay payment, Wallet or PayLater, you need to provide different parameters in the /payments request.

Handle the redirect

Use the Redirect Component to redirect the shopper to GrabPay to complete the payment.
After the shopper returns to your app, make a POST /payments/details request from your server, providing:
- details: The actionComponentData.details object from the Redirect Component.

You receive a response containing:

resultCode: Use this to present the payment result to your shopper.
pspReference: Our unique identifier for the transaction.

For GrabPay PayLater, the response also contains additionalData.paymentMethodVariant — the Adyen sub-variant of the payment method used for the payment request. Possible values:

For GrabPay Wallet: grabpay_wallet_SG, grabpay_sg, grabpay_wallet_MY, grabpay_my, grabpay_wallet_PH, grabpay_ph
For GrabPay PayLater: grabpay_postpaid_SG, grabpay_instalment4_SG, grabpay_postpaid_MY, grabpay_instalment4_MY.

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.

If the shopper closed the browser and failed to return to your website, wait for webhooks to know the outcome of the payment. The webhooks you can receive for GrabPay are:

AUTHORISATION	true	The shopper successfully completed the payment.	Inform the shopper that the payment has been successful and proceed with the order.
