Is it possible to modify Form Redirect URL before sending it?

Hi,

I’m able to “construct” the Form Redirect URL using GET action and named input fields, but…

…instead of having this as the Redirect URL: https://some-service.some-domain/?key1=value1&key2=value2

It should look like this: https://some-service.some-domain/value1value2

So just pass the native inputs added to the static URL string, no key strings and no special characters.

If that was to be done using javascript then what value should be modified and how to trigger it to happen at right moment?

Also, for real, the value2 should be just a randomised 10 digit alphanumerical string.

I guess the question is can we catch and edit the GET Redirect URL before Webflow has fired it up.

Best Regards,
Tomas
