Desktop/Mobile Website Browser
Accept Multibanco payments on your website by redirecting shopper to Multibanco payment page. See checkout process below:
- The shopper selects Multibanco as their preferred payment method
- The shopper redirected to the bank selection page where they select their preferred bank
- Multibanco loads a new page with references and payment instructions
- The shopper is redirected to the bank page where they enter the supplier ID, reference, and payment amount and authenticate the payment
- The payment resulted is displayed as successful
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.
Step 2. Get available payment methods
To be able to display Multibanco as a payment option on your checkout page, you need to get available payment methods from Airwallex API.
When the PaymentIntent is created, send a GET request with parameters country_code, transaction_currency, transaction_mode to API endpoint /api/v1/pa/config/payment_method_types to query for a list of available payment method based on the information provided. The response will also contain the required fields and necessary resources of each payment method for you to display them on your page.
Request:
Response: Render payment methods in items to show all available payment methods to the shopper at checkout page.
Alternatively, you can maintain available payment methods and corresponding resources locally on your server if you do not want to use this API endpoint. However, we highly recommend you get available payment methods dynamically from this API to avoid any trouble when payment method information or resources get updated.
Step 3. Redirect to Multibanco to complete payment
When a shopper selects to pay with Multibanco on their desktop/mobile browser, call the following API endpoints to get the URL which you can use to redirect the shopper to Multibanco payment page to complete the payment.
- Obtain URL from Airwallex and redirect shopper to Multibanco
Request:
Response: Render the value of url to redirect shoppers to Multibanco.
- 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 Multibanco.
- Query the PaymentIntent status
You may also query the status of a payment anytime via the PaymentIntents API
