WeChat payment support has been added. I am unable to test it so if you use it and run into an issue send me a message or email.
Update: This has been tested and appears to work.
Update: WeChat has been removed due to some issues with it taking the payment then not allowing my system to process it (it eventually gets refunded). It is in beta so I’ll wait until it’s out of beta to re-enable it. Alipay works perfectly and can be used instead.
