FORMHUSH / Wix

Filter Wix contact form spam

Embed a FormHush contact form on Wix from a controlled HTTPS page. Check the iframe origin, layout and thank-you navigation before connecting it.

A FormHush form can sit inside a Wix page as an embed. It is a separate collection path, so existing Wix Forms records, notifications and automations will not automatically receive its submissions.

Host the form and embed its URL

Put the HTML below on an HTTPS page you control. In Wix, choose Embed a site and enter that page’s URL. The Wix embedding documentation explains the difference between an HTML embed and a site embed.

Register the hosted form page’s exact HTTPS origin in FormHush. Raw inline embeds can have a different or opaque origin; do not assume the request comes from your visible Wix domain, and do not allow a generic null origin as a workaround.

Before connecting

The site is a preview. Accounts and forms are provisioned by an operator; the dashboard does not create them. Obtain a provisioned form ID and have the operator configure allowed origins, notification destinations and any thank-you URL before using the integration.

The examples use https://api.formhush.com/f/example-contact. Replace the illustrative example-contact ID with your provisioned ID; it is not a live demo form. Keep account keys out of public markup. Browser requests must come from an exact allowed origin, including the scheme and any port.

<form action="https://api.formhush.com/f/example-contact" method="POST">
  <label for="contact-name">Name</label>
  <input id="contact-name" name="name" maxlength="120" autocomplete="name">
  <label for="contact-email">Email</label>
  <input id="contact-email" name="email" type="email" maxlength="254" autocomplete="email">
  <label for="contact-message">Message</label>
  <textarea id="contact-message" name="message" maxlength="8000" required></textarea>
  <input name="website" type="text" hidden tabindex="-1" autocomplete="off">
  <button type="submit">Send message</button>
</form>

Check iframe sizing and navigation

Set enough embed height on desktop and mobile to show every field and the submit button. The hosted page must permit framing, and the iframe must permit form submission. Confirm the actual request Origin in browser developer tools.

The thank-you page normally loads inside the iframe. It must also allow framing; otherwise the browser can block it after an accepted submission. Test that view before using the form with visitors. This guide does not require removing your other Wix forms.

Fields and thank-you behaviour

message is required, up to 8,000 characters. name is optional, up to 120 characters; email is optional, up to 254 characters and must be valid when supplied. The website string is mandatory and must stay empty for a legitimate visitor. A filled honeypot is stored as spam, not silently discarded.

Only JSON and URL-encoded POST bodies are accepted, with a 16,384-byte limit. Additional fields are not stored. FormHush does not use _gotcha, and a submitted _redirect does not control navigation.

For a native URL-encoded form, the operator sets the form’s HTTPS thank_you_url during provisioning. An accepted request then returns HTTP 303 to that URL. Without it, the endpoint returns HTTP 201 JSON. JSON requests always receive JSON; a JavaScript form handles its own success state or navigation after checking the response.

Classification, delivery and retention

Rules check the honeypot and known spam patterns first. When configured, Jev classifies the remaining message text after email addresses and phone numbers are masked. That masking is not complete anonymisation. Ambiguous decisions stay in Needs review without automatic forwarding.

Real leads and urgent messages are queued for configured destinations. When AI is unavailable, remaining accepted messages become Unsorted and are also queued; deterministic spam rules still apply. Delivery adapters support email, Slack, Telegram and webhooks, but need operator configuration. The email provider is not yet selected. Retries do not guarantee that a third party receives a message.

Submissions and related notification jobs are deleted after 30 days by scheduled cleanup. Copies sent to your channels follow those services’ retention policies. Processing can involve the United States; see the privacy policy for providers and details.

Test the complete flow

1. Test from an allowed origin using a provisioned form. Submit a clear enquiry and check its stored result in the dashboard.
2. Check delivery separately, using a configured test destination. An accepted response alone does not prove notification delivery.
3. Send a nonempty message with website filled to verify that it is stored as spam without notification. An empty message is a validation error, not a spam verdict.
4. Confirm a missing honeypot or empty message returns HTTP 400, an unsupported body format returns HTTP 415, and a disallowed browser origin returns HTTP 403.
5. Verify the thank-you page or inline success message and preserve entered text on errors. Rate and monthly limits return HTTP 429; respect Retry-After before retrying. Check for a stored record after a network failure to avoid duplicate submissions.
