In addition, logging out is not triggered by the web. This action is given to the APP to call the logging out API.But I don't know at this point what parameters to carry, and how to maintain the correct token

No,No,No。I mean, implement a way to log out using the API?
I found using token in the sellacious backstage submission event.Or can I modify the session state in the mysql table and can I exit the login state?

Hello,

If I understand right, you need logout button on your site? You can create a menu for the log out from Joomla administrator > Menus. Create a new menu and select Users > Log Out. Assign this menu item to the menu you want.

If this is not what you meant, let me know.

Thank You

I need to exit the page and do logout

Hello,

Can you explain more about your issue?
