公司多个不同的微信支付业务，但是微信只有一个回调地址咋办？The company has multiple different WeChat payment services, but WeChat only has one callback address, what should I do?

The company has many different businesses. Previously, it developed a wechat payment, applied for binding with a domain name, and has a callback address. Now other businesses of the company want to develop wechat payment, but what if there is only one callback address? The two businesses are completely irrelevant. They can't share a callback, and the callback address can't be added in the background. Now there are two technical development schemes. One is to redevelop the callback address so that it can support two independent and different payment systems at the same time. The other is to find a way to apply for adding a callback address. How to add a callback address? Can you apply for access to the callback address by adding a domain name
