We are currently using this plugin ([login to view URL]) to integrate our Gravity Form with SalesForce.
We have a multi-page form and would like to create the lead once they press next on the first page with the current data. Then on page 2 it would update the Lead within salesforce, page 3 update, and possibly update again on page 4.
The reason for this is if the user doesn't complete the form we would still like their information.
This is something we are willing to pay well for if it can be done within the next 24 hours or less.
