On this page, you can find additional configuration for adding GrabPay to your Drop-in integration.
Before you begin
This page assumes you have already:
- Built a Drop-in integration.
- Added GrabPay in your test Customer Area.
To make a GrabPay PayLater payment, you also need to collect and send additional information:
- The delivery address.
- Information about the purchased items.
API reference
Collecting and sending additional information is only needed for GrabPay PayLater payments. However, we highly recommend you do the same in your initial integration for GrabPay Wallet because it will help save development resources if you plan to enable GrabPay PayLater afterwards.
To make a GrabPay PayLater payment, either postpaid or installment, you need to send additional fields. Select which endpoint you're integrating:
This is the default with Web Drop-in v5.0.0 or later.
Parameter name Required Description 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. Drop-in configuration

Test and go live
To test your GrabPay integration:
- Contact our Support Team for your test wallet credentials.
- 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.
