Accept Taiwan Convenience Store payments on your website by redirecting shopper to payment page. See checkout process below:

1. The shopper chooses Taiwan Convenience Stores as preferred payment method on merchant’s checkout page
2. The shopper is redirected to ID Authentication page a. If this is the first purchase of current account, the shopper completes ID Authentication via Bank portal where they provide their bank account b. If not the first purchase, the shopper completes ID Authentication with ID number and a token sent to their mobile phone
3. The shopper is redirected to payment information page where Transaction ID and CVS pin-code is generated and displayed
4. The shopper takes a photo or a screenshot of the payment information
5. The shopper brings payment information to any of the supported convenience store and pay with cash
6. 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 \

11  }'

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 Taiwan Convenience Stores.

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}
