Domain restrictions
Setup your forms to only accept form submissions from a specific domain and all it’s subdomains.
Domain restrictions are only available on the Professional and Business plans.
Configuring your forms domain restrictions
Go to your form settings and scroll down to the Security section. Here you can add the domains and subdomains you want to restrict your form to.
In order to use Formbox’s domain restrictions you must ensure your site’s Referrer-Policy
sends your site’s origin information to Formbox.
By default, sites usually have the Referrer-Policy
set to strict-origin-when-cross-origin
which is compatible with Formbox. Learn more about referrer policy here.
