Can I prepopulate web form fields with salesforce data?

...and the answer is...Yes
FormTitan's integration with Salesforce is so powerful that it allows you to easily draw data from your Salesforce objects into your form fields in real-time. This is very significant when your fillers are already registered in your Salesforce data. Why make them fill in the same data all over again, when you can populate the fields for them, spare them the time and efforts of filling in the same details again (because we all know how much people "love" to fill in forms...). 

How exactly does this work?
In order to populate data from SF, all you need to do is configure a Get integration. In this integration you will need to:
- Authenticate with Salesforce.
- specify the object you want to connect to in SF
- Add a condition if needed
- Map the fields in your SF object to your form fields
and that's about it...
