My Answer:
Yes, it is possible to get a response after a user shares a post or feed on Facebook. One way to achieve this is by using the Facebook API.

You can use the Facebook API to track when a user shares a post from your website to their Facebook account. Once the user shares the post, you can use the API to retrieve information about the shared post, such as the post ID or the user's Facebook ID.

You can then use this information to authenticate the user on your website. For example, you can store the user's Facebook ID in your database when they register on your website. When the user shares a post, you can check if their Facebook ID matches the one stored in your database, and then authenticate them accordingly.

You can implement this functionality using JavaScript to handle the sharing process on the front end, and PHP to handle the authentication process on the back end.

Please note that you will need to have a good understanding of the Facebook API and how to integrate it with your website in order to implement this functionality successfully.
