GrabPay iOS Component

Our GrabPay Component renders GrabPay in your payment form, and redirects them to GrabPay's webpage.

When making a GrabPay payment, you additionally need to:

• Handle the redirect.

Before you begin

This page explains how to add GrabPay to your existing iOS Components integration. The iOS 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 for making API requests.
2. Add GrabPay in your test Customer Area.

Show GrabPay in your payment form

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

1. Specify in your /paymentMethods request:

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

2. Decode the /paymentMethods response and find the payment method with type grabpay_XX, where XX is the country code.

Make a payment

When the shopper proceeds to pay, the Component invokes the didSubmit method containing the data.paymentMethod from the PaymentComponentDelegate.

1. Pass the data.paymentMethod to your server.
2. From your server, make a /payments request, specifying:
   • paymentMethod.type: The data.paymentMethod from your client app.
   • returnUrl: The URL the shopper will be redirected back to after they complete the payment.

    },
    reference: "YOUR_ORDER_NUMBER",
    merchantAccount: config.merchantAccount,
    returnUrl: "my-app://"
}).then(res => res);

The /payments response contains:

• action: Object containing information about the redirect.

{
    "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..."
    }
}

2. Pass the action object to your client app. You need this to initialize the Redirect Component.

Handle the redirect

1. Use the Redirect Component to redirect the shopper to GrabPay.

2. After the shopper returns to your app, make a POST /payments/details request from your server and provide the data from the didProvide method from your client app.
   

   https://docs.adyen.com/payment-methods/paytm/ios-component#-payments-details-request

   /payments/details request

     {
      "{hint:data.paymentData from didProvide}paymentData{/hint}":"Ab02b4c0!BQABAgCJN1wRZuGJmq8dMncmypvknj9s7l5Tj...",
      "{hint:data.details from didProvide}details{/hint}":{
        "payload":"Ab02b4c0!BQABAgCW5sxB4e/=="
      }
   }

   You receive a response containing:

   • resultCode: Use this to present the 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:

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:

Recurring payments

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.
