Pull field data from external APIs and other sources

In some cases, options for fields are dynamic. This could be the case of a product catalog, A/B testing, or just event pulling data from a CMS. I find Tally to be a really flexible option compared with several competitors, and this feature is something that could make the product even more interesting for more mature projects, not just simple MVPs or more normal cases. Just the idea of having some API either for dynamically changing the Form asynchronously, or adding a configuration option to certain fields to pull data from will be an incredible Dev Experience enhancement.

Thanks so much for the thoughtful suggestion — and for explaining the use case so clearly! ✌️ Right now Tally can't query a database or CRM live to pull in the rest of the fields from one initial input. Hidden fields passed through URL parameters are the only way to feed external data into a form today, so what you're describing isn't something we offer yet. I've noted it down and we'll keep it in mind as we decide what to build next.

Being able to connect with flightaware and get flight info right into the form would be very helpful.
