Need a way to secure Prefill URLs in Zoho Forms (hide or encrypt prefilled values)

Need a way to secure Prefill URLs in Zoho Forms (hide or encrypt prefilled values)

Hi everyone,

I often use Zoho Forms with prefilled URLs to simplify the user experience — for example:
https://forms.zohopublic.com/.../form?Name=David&Amount=300

However, the problem is that all prefilled values are visible and editable in the link.
That means a user can easily change those parameters manually (for example, change the amount or ID), and the form will still load with the modified data.

I’m looking for a secure way to pass prefilled data — for example:

  • Some kind of encrypted token that only Zoho can decode

  • Or a way to generate a “static prefill” that hides the field values from the URL

Does Zoho Forms currently support this? Or is there a known workaround using Zoho Flow / Creator / API to achieve a secure prefill without exposing data in the URL?

Thanks!
