After first login Login page is not appear and throw redirect url

fist time when I open login url on browser
"…zoom.us/oauth/authorize?response_type=code&client_id=&redirect_uri= "
it open login page on browser from my C# desktop app. I am using Process.Start(url)
after signin it will redirect and I will listen the code.
But when again run Process.Start(url) it open the browser and don’t show login page and redirect me. when I clear the browser history only then Login page is visible.
I need to display login page each time when user open the url. Any help please?

Hi @islam.rakibul,

This would be expected behavior. If a user has already authorized your OAuth App and has an active session, Zoom will not request them to login again for at least some time.

If you need to force this, you might try clearing cookies after you receive the code parameter each time.

Thanks,
Will
