It's simple. You can find the interface of Alipay on your website. There is a personal credit card payment method in Alipay, and the interface of Alipay is Alipay interface (which can be found on Alipay website or Baidu Alipay interface application). I used to be an Alipay interface. I remember that it is free to sign an electronic agreement every year. Be sure to go to Alipay official website to find an interface application and be cheated. I hope my answer is helpful to you! ~
