Complete user profile after social public registration I use Dukt plugins (-oauth and -social) for public front-end registration. I would like complete user profile after registration (e.g. license agreement checkbox). 

How is it possible to accomplish this? 

I would like intercept social callback after authentication and show a custom page.... I suppose OnBeforeSave event is not useful for this scenario. Thanks
Via https://dukt.net/craft/social/docs/templating/craft.social#getLoginUrl you may give up a page like { redirect: 'user/finish' } on which you could check if a user agreed to the license agreement and if they have redirect them to the regular page.

Here is an example profile edit page that might be useful https://github.com/dukt/social-demo/blob/master/craft/templates/social/profile.html
