I see a lot of people who either want to have a participant id in hidden field or a random number in a hidden field.

Typeform has this amazing feature, where you can use a hidden field as the suffix to a redirect URL
ex: redirect/?@hiddenfield

This being randomized would be great for those using embeds and custom results handling. As when the redirect occurs web hooks can more easily read the url unique code and match it to data.

Example for my use case:

Zapier sends my quiz responses to chat gpt and airtable stores chatGPTs response as well as the hidden field.

I can then use Framer to read the URL and match the GPT response to the hidden field in the database that matches the redirect URL. Bypassing a lot of coding and web hook stuff that could be simplified with the existing functionality.

Why doesn't this exist, and is there a work around.

I looked in another thread and the “best answer” to typeform lacking UUID was someone suggesting to format a question as a random number generator, which is obviously not the ideal solution for a customer facing quiz.
