Native Velo Script (Zero Dependencies)
Copy this lightweight snippet into your Wix Studio page code to stream submissions natively without embedding external iframes:
import { fetch } from 'wix-fetch';
$w.onReady(function () {
$w('#submitButton').onClick(async () => {
// 1. Prepare form submission payload
const payload = {
formId: 'YOUR_FORM_ID', // Replace with your Form ID from FormWix Dashboard
data: {
email: $w('#emailInput').value,
name: $w('#nameInput').value,
notes: $w('#notesInput').value
}
};
// 2. Dispatch to FormWix High-Speed Endpoint
const res = await fetch('https://formwix.com/api/v1/submissions', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(payload)
});
if (res.ok) {
$w('#successState').expand();
$w('#formContainer').collapse();
}
});
