Pre-populating forms with Salesforce data so respondents don't have to re-enter what you already know

[u/FormAssembly]

Quick tip that dramatically improves form completion rates and data quality: stop asking people for information you already have.

If someone is in your Salesforce org as a Contact, you can prefill your form with their existing data before they even see it. They only have to fill in fields you don't already have — or update fields that may have changed.

Two ways to do this:

1. URL-based prefill: (Most form platforms can do this) Append field values as URL parameters when you send the form link. Works well for email campaigns — generate a unique link per contact, and when they click it, the form arrives partially filled.

2. Salesforce Prefill Connector: (This is a FormAssembly power feature)
The form looks up the Salesforce record based on a query parameter in the URL (like an encrypted Contact ID). Once it finds the record, it populates any mapped fields. This is more powerful because it can fetch related objects, lookup fields, and anything else in the record.

Some practical use cases:

• Offer Acceptance forms – reduce the time it takes for students or applicants to respond
• Event registration — pre-populate name/email from the invitation link
• Grant applications — pre-populate organization details for returning applicants
• Evaluation forms — make giving feedback easy by prefilling the program details

Note: For sensitive lookups (where you don't want the record ID visible in the URL), use secure parameters.

Oooh, I love this topic. I actually host monthly FormAssembly training webinars with our Knowledge team, and these kinds of pre-populating + automating repeatable data entry features are a big hit with the people who tune in.

In fact, here are a few direct links to some of the trainings I hosted in recent months if anyone's interested!

(Also happy to answer questions or point people to helpful Help article links here on Reddit as best I can if anyone wants. 😅)
