# How secure is Contact Form Integration?

The feature is highly secure:

- Webhook submissions use HTTPS for encrypted data transfer.
- The webhook UID is unique and should be kept private (never exposed in client-side code).
- Embedded forms are tied to whitelisted domains, preventing unauthorized use.
- Rate-limiting (one submission per IP per hour) reduces spam.
- Only your server/domain should send webhook requests.
  Follow our security tips in the setup guide to ensure protection.
