How to display news from a Facebook group on your website?

Question

Facebook

The application requires an App ID and an App Secret key.
I created a Facebook application, got an ID and a key and entered them in the application. BUT, in fact, I just need publications from Facebook to the site, not vice versa. And it is not clear why the application should be created at all, and if it is still necessary, then what settings should be made in it in order to make publications from Facebook to the site work through the application.

Answer 1

The question is quite general and there are no specifics...
1) I understand that you have some plugin installed that requires you to create an application and enter an ID?
If so, then most likely the plugin accesses the group through the Facebook API and, accordingly, you need to create an application. Another question is whether the basic rights are enough for the application or whether new ones need to be requested. Most likely the basic rights should suffice. If I'm not mistaken, then for fb you also need a certificate installed on your site (you can take a free lets encrypt)
