Moodle autologin plugin - how to direct user to a specific course?

I am building a laravel web application which involves the usage of Moodle Service (version 3.6). I have done autologin with a [plugin](https://github.com/catalyst/moodle-auth_userkey). The problem is that clicking the **Take Course** button on my external application will autologin to Moodle (via the plugin), but does not redirect the user to the course described in the button. Is there a mechanism to do this?
