WeChat Pay - APP Payment

Answer 3

Payment can’t be explained in a few words. If you don’t clarify the process, you won’t be able to understand it even if I give you a demo. Let’s read the documentation first. Although the WeChat documentation is terrible, it is recommended to read Alipay’s documentation first. It’s easy to get started. There were a lot of pitfalls in the payment area at the beginning.
