First, register the WeChat public platform. Generally speaking, for our self-employed, we can only register our personal subscription number, but we can't authenticate it. After logging in to the WeChat public platform, set relevant information by yourself. As for how to apply and how to set it up, many friends have said that you can check other experiences of Baidu.

1. After I started the secondary development of WeChat, I suddenly found that the custom menu I set before I started the development was gone. Look carefully for reasons on the internet. It is found that the current menu configuration is invalid and disabled because the developer modified the menu configuration through the interface. You can go to the developer center to disable it.

2. If you go to the developer center and make a careful inquiry, you will find that this function has no interface of personal subscription number. It can only be used after authentication. If so, I think we should simply authenticate ourselves, but I found that Tencent does not allow personal subscription number authentication. I was speechless, so I studied it carefully and found a way to make the custom menu appear again.

3. Click Add Function Plug-in on the left, and I see a custom menu on the right. When I clicked in, I found a statement that the unauthenticated subscription number can only use the custom menu function in edit mode, and the related interface ability of the custom menu can only be used after the authentication is successful. Anyway, I'll click Enable again and see what happens.

4. After clicking Enable, the background color of the open button changes from red to green, which should be turned on. If I go to WeChat to see if the official account of WeChat has changed, I didn't expect the custom menu I set up before to appear again, indicating that this method can be used.
