Accept Maxima cash payments on your website by redirecting shopper to Maxima payment instructions. See checkout process below:

1. On the merchant’s checkout page, the shopper selects to pay at a Maxima store
2. The shopper is redirected to a page where they receive a payslip containing a barcode. They can download the payslip and print it out
3. The shopper takes the payslip to a Maxima store and pay with cash
4. The payment is confirmed

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": 20,
8    "currency": "EUR",
9    "merchant_order_id": "85d7b0e0-7235-11ea-862e-9f6aa1adfca6"
10    "return_url": "https://www.airwallex.com"
11  }'

Step 2. Redirect to Maxima payment instructions to complete payment

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

1. Obtain URL from Airwallex and redirect shopper to Maxima

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":
8    {
9      "type": "maxima",
10      "maxima": {
11        "shopper_name": "first_name last_name",
12      }
13    }
14  }'

Response: Render the value of url to redirect shoppers to Maxima.

Shell
1{
2   "next_action": {
3       "type": "redirect",
4       "method": "GET",
5       "url": "https://r3.girogate.de/ti/simmaxima?tx=957024256&rs=Yhbs8CJZjTkWjMDh3g7YGeuhqBUkIzwF&cs=1b87641dac985e466dabf882a4219e4e0853ab00cc64fb4958d4d7053087efcd"
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 Maxima.

3. Query the PaymentIntent status

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

Shell
1    GET /payment_intents/{id}
