Integrate Gravity Forms with Janrain Engage social login to pre-fill forms.
This plugin allows you to integrate your existing Janrain Engage sign-in application with any form in Gravity Forms and use users' social profile data to prefill fields.
After activating the plugin and entering your Engage app settings on the Forms > Janrain Settings page, a "Social Login" field will be added to the list of available fields in Gravity Forms. All other fields will have a new setting for "Prefill from:", where you can elect to let that field be prefilled from the social profile data, and choose which data to use as a prefill.
Works with the free Basic app available from Janrain - sign up at http://rpxnow.com - although some extended profile data fields are only available with the Plus level ($10/mo - see Janrain Engage Pricing for more information.)
