Step-by-step guide: How to Upload & Store Wix Form Files in AWS S3 Cloud Storage (2026 Tutorial)When a visitor submits a Wix or Wix Studio form, FormWix validates the input at the edge and dispatches the payload to AWS S3 Cloud Storage synchronously without queuing delays:

}How to Connect AWS S3 Cloud Storage to Wix Studio (3 Steps)
Copy Your Endpoint
Provide your S3 Bucket Name and IAM credentials with PutObject permissions.
Bind to Native Wix Studio Form
FormWix generates secure pre-signed upload URLs for client files.
Authorize AWS S3 Cloud Storage Destination
Files upload directly to your S3 bucket, saving storage bandwidth and eliminating file loss.
Supported Fields & Schema Mapping
FormWix automatically reconciles and normalizes these field names when forwarding data into AWS S3 Cloud Storage:
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();
}
});
