How to add utm tags to a wix form? - webhooks

Question

I am currently attempting to include UTM tags in a webhook that I am sending from a wix form. However, upon sending the webhook, I am either receiving an empty response or receiving "google.co.il" source. I am expecting specifically Google Ads or email sources.
I have added the code that I am using in an attempt to make this function properly. Any assistance or guidance would be greatly appreciated..
export function wixForms1_wixFormSubmitted(event) {
var obj = {};
var i = 0;
for (i=0;i<event.fields.length;i++){
obj[event.fields[i].id] = event.fields[i].fieldValue;
}
//console.log(obj);
fetch( "https://hook.eu1.make.com/62tsltjotop6iwboufggguuxhhqrjaen", {
"method": "post",
"headers": {
"Content-Type": "application/json"
},
"body": JSON.stringify(obj)
} )
.then( (httpResponse) => {
if (httpResponse.ok) {
return httpResponse.json();
} else {
return Promise.reject("Fetch did not succeed");
}
} )
.then( (json) => console.log(json) )
.catch(err => console.log(err));
}
$w.onReady(function () {
const query = wixLocation.query;
if (query) {
$w('#refbox').value = JSON.stringify(query);
}
let params = wixLocation.query
console.log(params)
$w('#campaign').value = params.campaign_name
$w('#source').value = params.utm_source
});
import wixWindow from 'wix-window';
import wixLocation from 'wix-location';
});
import wixWindow from 'wix-window';
import wixLocation from 'wix-location';
import {local, session, memory} from 'wix-storage';
let referrer = wixWindow.referrer;
let previousPageURL;
$w.onReady(function () {
previousPageURL = session.getItem("page");
session.setItem("page", wixLocation.url);
});
$w.onReady(function () {
// Write your JavaScript here
const prvurl = wixLocation.url;
if (prvurl) {
$w('#prvurl').value = JSON.stringify(prvurl);
}
// To select an element by ID use: $w("#elementID")
// Click "Preview" to run your code
const query = wixWindow.referrer;
if (query) {
$w('#refbox').value = JSON.stringify(query);
}
}
);
