How to retrieve the session token using wp_get_session_token in WordPress
The wp_get_session_token function in WordPress is designed to retrieve the current session token. It is a part of the WordPress core and is used in the process of verifying the identity of a logged-in user.
This function operates by accessing the user’s cookies and extracting the session token.
