I'm making a project and i'm using RoR as a back-end and angularJS as a front-end, I'm stuck with register using linkedin, I have followed this tutorial link and it helped me, but my application needs more information from user to be entered while registering which is not on linkedin, So what i thought about is to redirect_to the sign_up page and attach (auth.uid) parameter to the url (like: https://example/signup?uid=ude3f4J) and make the user fill the rest of needed parameters in the form, Is this the best way to do it, Is (auth.uid) is very important thing that i shouldn't send it in the url? Is (auth.uid) something that i should protect?
Thanks
