Gravity Forms Janrain Add-on

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.)
