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:

    countryCode amount.currency
    MY MYR
    PH PHP
    SG SGD
    TH THB
  2. Decode the /paymentMethods response and find the payment method with type grabpay_XX, where XX represents the country.

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.

    "action": {
        "method": "GET",
        "paymentData": "Ab02b4c0!BQABAgBlmvU6H9LnijLzrYAgMfopoX...",
        "paymentMethodType": "grabpay_SG",

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

Handle the redirect

Use the Redirect Component to redirect the shopper to GrabPay. After the shopper is redirected back to your app, make a /payments/details request to check the payment result.

For more information and detailed instructions, refer to Using the Redirect Component.

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 request that they 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, you first need to create a shopper token and then make subsequent recurring transactions with the token.
Refer to Tokenization for more information and detailed instructions.

Test and go live

To test your GrabPay integration:

  1. 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.
  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.
