How to make approval for assigned tasks from email without bonita portal?

Hello,
I’ve created a process for vacation requests. I want to make approvals or refusals from mail. I want create approve and refuse links and assigned user only click button in mail to approve or refuse. But i dont know how to manage that or even it is possible. Any help would be appreciated.

Best Regards,
Sakir

It is possible by embedding links in the email to call Bonita REST APIs but the user needs to be authenticated. When a user clicks on the link they will be brought to the login screen where a user can enter their credentials.
