The WeChatPay service supports two actions: Pay and Refund.
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.
