# Wix

MuxForms on Wix is typically an Embed HTML element with div + embed.js on Business plans that allow custom code. Velo can POST JSON from backend/http-functions with the ingest secret when the UI is custom.

## Wix paths

| Path | When |
| --- | --- |
| Embed HTML | Standard MuxForms UI |
| Velo fetch | Custom Wix input elements |
| Allowlist | https://www.yoursite.com |
| Secrets | Velo Secrets only—not client |

## Embed HTML widget

```
<div data-form-id="FORM_UUID"></div>
<script src="https://www.muxforms.com/embed.js" defer></script>
```

## Velo backend example (custom UI)

```
// backend/http-functions/submit.jsw
import { fetch } from 'wix-fetch';
import { getSecret } from 'wix-secrets-backend';

export async function post_submit(request) {
  const body = await request.body.json();
  const secret = await getSecret('MUXFORMS_INGEST_SECRET');
  const res = await fetch('https://www.muxforms.com/api/v1/forms/FORM_UUID/submit', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `Bearer ${secret}`,
    },
    body: JSON.stringify({ email: body.email, message: body.message, _hp: '' }),
  });
  return { status: res.status };
}
```

## FAQ

### Free plan embed?

HTML embed availability depends on Wix plan; check Embed → Custom code.

### Wix Forms app?

MuxForms is for teams also running non-Wix stacks.

### Velo CORS?

Server-side Velo POST has no browser CORS; browser embed needs allowlist.

### Multilingual Wix?

One embed per language page or one form with locale hidden field.
