Accept Malaysian GrabPay payments on your website by redirecting shopper to GrabPay payment page. See checkout process below:

1. The shopper selects to pay with GrabPay on merchant checkout page
2. The shopper is redirected to GrabPay authentication page where they log into their GrabPay account
3. The shopper confirms the payment and pays
4. The shopper is redirected back to payment success page

Step 1. Initialize a Payment Intent

Create a PaymentIntent object with a request_id, amount, currency and a merchant_order_id from your backend server.

Shell
1curl -X POST \
2  https://api.airwallex.com/api/v1/pa/payment_intents/create \
3  -H 'Content-Type: application/json' \
4  -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiJhNDc...' \
5  -d '{
6    "request_id": "ed11e38a-7234-11ea-aa94-7fd44ffd1b89",
7    "amount": 10,
8    "currency": "MYR",  
9    "merchant_order_id": "85d7b0e0-7235-11ea-862e-9f6aa1adfca6"
10    "return_url": "https://www.airwallex.com"
11  }'

Step 2. Redirect to GrabPay payment page to complete payment

When a shopper selects to pay with GrabPay on their desktop/mobile browser, call the following API endpoints to get the URL which you can use to redirect the shopper to GrabPay payment page to complete the payment.

1. Obtain URL from Airwallex and redirect shopper to GrabPay payment page

Request:

Shell
1curl -X POST \
2  https://api.airwallex.com/api/v1/pa/payment_intents/{id}/confirm \
3  -H 'Content-Type: application/json' \
4  -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiJhNDc...' \
5  -d '{
6    "request_id": "ed11e38a-7234-11ea-aa94-7fd44ffd1b89",
7    "payment_method": {

9        "grabpay": {
10            "shopper_name": ""
11        }
12      }
13    }
14  }'

Response:

3      "type": "redirect",
4      "method": "GET",
5      "url": "https://r2.girogate.de/ti/T1138/I?tx=948883081&rs=yY4QjVwxlu805HRX6Bp4nO1cDzx4Y7JG&cs=6a6cf3a6eb18b6e26844a940bdced3428f6e58b151130b34d2f9336ca32bfc77"
6  }
7}

2. Wait for notification from Airwallex

Airwallex will notify you on the payment result asynchronously via the webhook API.  Please refer to webhook documentation to set up your webhook accordingly. Although subscribing to different events is optional, it is recommended to at least subscribe to the payment_intent.succeeded which indicates that the shopper has successfully paid for the order via GrabPay.

3. Query the PaymentIntent status

You may also query the status of a payment anytime via the PaymentIntents API

1GET /payment_intents/{id}
