Collect Request - Redirect 302

Server Google Analytics

Dear Stape Community,

my site in production is made with Prestashop and is on the following domain:

smanique.com

I created a test environment to test stape by creating a subdomain where I cloned my site:

stg.smanique.com

I set up the server-side container following this guide:

and I configured a custom tagging URL with the following subdomain:

t.smanique.com

I changed the GTM code in the module that manages GTM and datalayer on Prestashop for UA so that it uses the subdomain t.smanique.com:

<script data-keepinline="true">
    var ajaxGetProductUrl = '//stg.smanique.com/en/module/cdc_googletagmanager/async?obj=cart-action';

/* datalayer */
dataLayer = window.dataLayer || [];
dataLayer.push({"pageCategory":"product","ecommerce":{"currencyCode":"EUR","detail":{"products":[{"name":"Afrodite - Bedazzled Stainless Steel Bracelet - Apple Watch Series 2 - 38mm and 42mm Strap","id":"365-19854","reference":"","price":"49.99","brand":"Smanique","category":"Apple Watch Series 2 - 38mm and 42mm - Bands & Straps","variant":"38mm, Gold, One Size Adjustable","link":"afrodite-bedazzled-stainless-steel-bracelet-apple-watch-series-2-38mm-and-42mm-strap","price_tax_exc":"49.99","wholesale_price":"0"}]}}});
/* call to GTM Tag */
(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://t.smanique.com/hbmlvohn.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-T289WDP');


/* async call to avoid cache system for dynamic data */
var cdcgtmreq = new XMLHttpRequest();
cdcgtmreq.onreadystatechange = function() {
    if (cdcgtmreq.readyState == XMLHttpRequest.DONE ) {
        if (cdcgtmreq.status == 200) {
          	var datalayerJs = cdcgtmreq.responseText;
            try {
                var datalayerObj = JSON.parse(datalayerJs);
                dataLayer = dataLayer || [];
                dataLayer.push(datalayerObj);
            } catch(e) {
               console.log("[CDCGTM] error while parsing json");
            }

                    }
        dataLayer.push({
          'event': 'datalayer_ready'
        });
    }
};
cdcgtmreq.open("GET", "//stg.smanique.com/en/module/cdc_googletagmanager/async?obj=user" /*+ "?" + new Date().getTime()*/, true);
cdcgtmreq.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
cdcgtmreq.send();
</script>

I set up UA server-side following this guide:

Now when I visit a stg.smanique.com page, two collect requests are made:

3 - Collect Requests
3 - Collect Requests867Ɨ63 3.83 KB

  1. One request with domain t.smanique.com with status 302 which redirects to stats.g.doubleclick.net
  2. One request with the domain stats.g.doubleclick.net with status 200

Furthermore, the assistant tag detects the request sent to Google Analytics:

Metadata
Web Property ID: UA-165678681-1
Protocol version number: 1
User ID: guest_134

Could you help me figure out where Iā€™m wrong? Thanks so much.

I solved the problem. I used the following module before:

Google Tag Manager Enhanced Ecommerce (UA) - PRO Module

I now use the following:

Premium Google Tag Manager Module

and all requests are sent successfully.
