Fallback success message if no redirect is set
Perfect For
How the redirect is chosen
A plain HTML form post is answered with a 302. Add a hidden `_redirect` field and the visitor lands there; leave it out and they land on Formboost's default thank-you page. The URL must be HTTPS and on the same host as the page that submitted the form — a `_redirect` pointing anywhere else falls back to the default page, which is what stops someone posting to your endpoint from their site and bouncing your visitors to theirs.
A fetch() or XHR request is never redirected: it receives 202 with a JSON body, and your JavaScript decides what to show next. Query parameters on the redirect URL are kept, so `?src=pricing` survives for your analytics.
<form action="https://formboost.app/f/YOUR_ENDPOINT_ID" method="POST">
<input type="hidden" name="_redirect" value="https://www.example.com/thanks?src=pricing" />
<input type="email" name="email" required />
<button type="submit">Subscribe</button>
