Docs: Custom redirect URLs

You can configure where users are redirected after interacting with your hosted contact form.

  • Confirm URL — where users go after a message is successfully sent
  • Cancel URL — where users go if they cancel the form
  • Error URL — where users go if an error occurs during submission
Default behaviour
  • Without custom redirect URLs, the user stays on the hosted form page.
  • A success or error message is shown on the form itself.
Redirect URL restrictions
  • URLs must use http or https.
  • URLs must have a valid host.
  • Each URL can be set independently. You do not need to set all three.
Configure redirect URLs
  • In your profile, under a contact form, find the redirect URL settings.
  • Enter the full URL for confirm, cancel, and/or error redirects.
  • Save the changes. The URLs take effect immediately for the hosted form.
