I don't quite understand what you mean. Do you want to use a company or institution for authentication by modifying the subject information? Is it possible to get a customized menu by paying the annual 300 yuan fee? This also needs to change the official account name of WeChat, which must be consistent with the name of the company that provides the certification materials, or abbreviated, or a subordinate trademark brand. This is clearly stated in the certification help file. There was a time when this function was a bit confusing. Some people suggest that we can scratch the edge in theory, but my vision is limited. I only see the theory but not the examples.
3. Try a third-party platform. When I first played the official WeChat account, I also dared to take this business. Now I am playing development mode. Looking back, many third parties stopped. Tencent is now in charge of more and more.
