Welcome to the community, @Caleb_Gonzalez1! :grinning_face_with_big_eyes: Sorry that your question has gone unanswered for so long.

At this time, prefilling only works with visible fields using Airtable’s native forms. If you use a third-party form solution like Jotform, though, you can pass data for both visible and hidden fields.

We’ve added this feature to our form extension. Now you can prefill hidden fields.
