Social media integration?

Question

JavaScript

It is necessary to implement the following functions, the user in the input writes a link to a group in social networks, after that I have to get information about this group. How will it be correct to write this to connect the API of all 8 social networks or is there an easier way? I think you can parse the page, but I don’t know how to do it, if the site is written in React and there is no backend.
