Building Forms
Redirect after submit
After a respondent submits, formbase shows the success screen for three seconds, then sends them to your URL — your site, a page you own, or a downstream tool.
Setting up a redirect
In Form settings → Submissions:
- Redirect URL — where to send the respondent after submission
- Redirect URL query parameters — optionally append field values to that URL
Only http and https URLs are used. A bare host like yoursite.com/welcome is treated as https://yoursite.com/welcome; anything that is not a valid URL is ignored and the respondent simply stays on the success screen.
What respondents see
The success screen appears with a three-second countdown — “Redirecting in 3 seconds…” — in place of the Submit again and Edit your response buttons, then the browser navigates. If you also built a thank-you page, your content shows during that countdown.
Query parameters
Add a row per parameter: a name on the left, a field on the right. The picker groups what you can send as Form fields, Hidden fields, Calculated fields, and Metadata (submission ID, submitted at, form name, generated PINs and codes). The settings page previews the finished URL as you type.
Values are URL-encoded. Example:
https://yoursite.com/welcome?email=alice%40example.com&plan=proUse this to:
- Personalize the destination page with the respondent’s name or email
- Pre-fill another form on your site
- Trigger analytics events with submission metadata
A member field of a repeating group sends one parameter per entry — ?guest=Alice&guest=Bob — rather than one joined value, so a comma inside an answer cannot corrupt the list. A whole group cannot be mapped to a parameter. Empty answers are left out of the URL entirely.
Redirect and 'Allow another response' are mutually exclusive
Setting a redirect URL turns off Allow another response, and turning that on clears the redirect. If respondents need to submit several times, use a thank-you page instead.
Embeds with autoClose
An embedded form opened with the autoClose parameter does not redirect —
the embed closes itself instead.
