WeChatPay - Buckaroo development portal

General

The WeChatPay service supports two actions: Pay and Refund.

Important note.

This service is not applicable for mobile payments:

- When performing a WeChat API call, a QR code will be displayed to the customer through the returned RedirectURL (on both desktop and mobile devices). It will not initiate the WeChat app.

- When performing a transaction API call without specified payment method, a redirectURL will be returned to redirect the customer to the Buckaroo Payment Page where a list of available payment methods will be displayed. WeChatPay will not be available in the list to mobile users.

Pay

The Pay action can be used to perform a payment.

Suggestion for implementation: use the billing address in the order information. If the billing country is China, send value zh-CN. If the billing country is Taiwan, send value zh-TW. Anything else, send value en-US. Another option is to check the customer's browser language.

Response 200 Status: Ok 400 Status: Access denied 500 Status: Bad request

JSON gateway response

The response contains two URL's; the RedirectURL and the QrCodeUrl. In general, the consumer should be redirected to the RedirectURL; a QR code will then be displayed to the customer to complete the payment. For mobile devices, this will not intiate the WeChat app, making this payment option not applicable for mobile payments.

QrCodeUrl string	The QrCodeUrl can be used for displaying the QR code on POS devices. But in general (for e-commerce transactions), the RedirectURL should be used to redirect the customer.
BankStatementId string	ID that will be shown on the customer’s bank statement.
expirytimestamp string	Timestamp that shows when the WeChat Pay QR code will no longer be valid.
