First, choose SmartSuite on the Integrate tab.

Then specify that you want to Update record.

You'll now get a formula that defines a unique link for every record in your table. In SmartSuite, create a new formula ****field and paste the formula Fillout provides.

That's it! Click Finish setup. Try out your form in Preview mode, or click one of your unique links to update a record after you’ve published your form!
Your form is automatically pre-filled for whichever record it is updating.
