We need to gather the ID's from users using
Facebook
Google+
and a German site called
[login to view URL]
I want to add it as a widget within the ZenDesk product, however when I tried to implement the Facebook API it would not work. So you may have to create a separate page insert in iFrame then try to get it via a cross site call.
Please visit:
[login to view URL] and click the "use external id" link to see desired functionality.
Please provide instructions on creating the Google+ & meinVZ apps as well.
