For which country do you want Alipay payment system ? Shopify does not have API of Alipay. Alipay also does not support for China. If you want to create custom API then we can do this and it takes more time and cost to you. So please kindly share more details with us so we can give you proper estimation with time frame.
Looking forward to your reply.
