GrabPay

Introduction

GrabPay uses a redirect-based payment flow. When a customer selects GrabPay at checkout, they are redirected to GrabPay's app or web interface to authenticate and confirm their payment, then redirected back to your website or app upon completion. GrabPay is a single-use payment method where customers must authenticate each payment.

This guide explains the process of integrating GrabPay into your app or website using Payrails.

Pre-requisites

Before you start accepting GrabPay payments with Payrails, there are a few requirements you must meet:

1. Integrate with Payrails using one of our SDKs or our API
2. Configure a new integration account for GrabPay via dLocal as a Payment Service Provider. If you do not have a dLocal integration already configured in your workspace, please follow the dLocal integration setup guide first.
3. Enable GrabPay as a payment method in your dLocal integration configuration. In the Payrails portal, navigate to Settings → Integrations, select your dLocal integration instance, and enable the GrabPay checkbox under Payment methods, then save the account.
4. Enable GrabPay as a payment option in your workflow.
5. Make sure you're sending the GrabPay-specific meta fields in your requests.

Ways to integrate GrabPay

Payrails SDK

The simplest way to use GrabPay with Payrails is to use our drop-in in your checkout flow. With this integration type, no additional work is required to accept payments with GrabPay except for handling success/failure screens for your users.

For a more flexible implementation using our SDK, you can use our genericRedirectButton element. See special instructions here for your client-side implementation.

Server-to-server integration

You can integrate GrabPay by completely managing your own client-side implementation, and using Payrails APIs with a server-to-server integration to process GrabPay payments.

Parse GrabPay from lookup response

With a server-to-server integration, you can call our lookup payment options endpoint to get available payment options. As shown in the example below, you can see grabPay returned as an option of the paymentCompositionOptions.

{
  "name": "lookup",
  "actionId": "0bb6413e-cabb-4074-99e6-9e815c69f25b",
  "executedAt": "2026-03-26T12:00:00.000000000Z",
  "data": {
    "paymentCompositionOptions": [
      {
        "integrationType": "redirect",
        "paymentMethodCode": "grabPay",
        "description": "GrabPay"
      }
    ]
  },
  "links": {
    "execution": "https://api.payrails.io/merchant/workflows/payment-acceptance/executions/83c534ac-13b7-43e6-b04b-f3e8b4eb4424",
    "authorize": {
      "method": "POST",
      "href": "https://api.payrails.io/merchant/workflows/payment-acceptance/executions/83c534ac-13b7-43e6-b04b-f3e8b4eb4424/authorize"
    }
  }
}

Pass GrabPay payment method in request to authorize payment with Payrails

You can then make a request to our authorize a payment endpoint with grabPay as the paymentMethodCode. See an example below:

{
  "executionId": "c0fd1c51-e709-47e5-bfd1-5d1c98f7d990",
  "amount": {
    "value": "50000",
    "currency": "PHP"
  },
  "paymentComposition": [
    {
      "integrationType": "redirect",
      "paymentMethodCode": "grabPay",
      "amount": {
        "value": "50000",
        "currency": "PHP"
      }
    }
  ],
  "meta": {
    "customer": {
      "name": "Juan Dela Cruz",
      "email": "[email protected]",
      "country": {
        "code": "PH"
      }
    }
  },
  "returnInfo": {
    "success": "https://mysuccessurl.com",
    "error": "https://myerrorurl.com"
  }
}

Note on amounts: PHP uses 2 decimal places. Amounts should be provided in the smallest currency unit — e.g., 50000 for ₱500.00.

Note: GrabPay is a redirect-based, single-use payment method. After calling the authorize endpoint, the customer will be redirected to GrabPay's app or web interface to authenticate and confirm the payment. Once confirmed, the customer will be redirected back to the returnInfo.success URL. Make sure to provide valid returnInfo URLs in your authorization request.

Handle the redirect response

After the customer completes the payment on GrabPay's side, they will be redirected back to your success or error URL. You should then verify the payment status by checking the workflow execution status via the Payrails API or by listening to webhook notifications.
