Set up your product feed (XML)
To advertise your products, we need your product XML feed in Google Shopping format. FastCentrik automatically generates this feed in your admin panel. Here’s how to find it and upload it to our app.
1. Get the URL of your product XML feed
A product XML feed is a file that contains information about your products (name, price, stock availability, images, etc.). FastCentrik generates this feed automatically in Google Shopping format. It’s available at a specific URL, for example:
Where to find it:
Log in to your FastCentrik admin.
In the left menu, go to Settings.
Under Tool Settings, click on XML Feeds.
In the list of available feeds, find the Google Shopping XML feed.
2. Upload the feed URL to the Tanganica app
Copy the URL of your feed.
Paste it into the designated field in our app.
Confirm.
✅ Done! If the feed is valid and in the correct format, your products will start syncing into the app.
3. What if you get an error?
❌ Wrong format → The feed must be XML, not CSV or JSON.
❌ Invalid structure → Some fields may be missing or incorrectly formatted (e.g., wrong prices or categories).
❌ Invalid URL → Try opening the feed URL in your browser to check if it loads an XML file.
Activate the Tanganica Pixel
The Tanganica Pixel lets you track ad performance, get detailed statistics, and unlock advanced features. On FastCentrik, the integration is done through Google Tag Manager (GTM).
1. Make sure you have a GTM container
Log in to Google Tag Manager with your Google account.
Check if you already have a container for your online store.
If not, create one:
Click Create Account, enter your business/store name, choose country.
In Container settings, add your store URL and select Web.
Click Create and accept the terms.
You can ignore the installation popup at this step (we’ll integrate it directly via FastCentrik).
2. Create a tag for Tanganica Pixel
Open your GTM container.
In the left menu, go to Tags → New.
Name it Tanganica Pixel.
Click Tag Configuration → Custom HTML.
Paste this code:
<!-- Tanganica pixel -->
<script>(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;
f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-TRS5RSN');</script>
<!-- End Tanganica pixel -->
Under Triggering, select All Pages (Page View).
Click Save.
3. Publish the changes
In the top right of GTM, click Submit.
Name your version (e.g., Add Tanganica Pixel).
Click Publish.
4. Connect GTM to FastCentrik
Copy your GTM Container ID (format: GTM-XXXXXXX, shown top right in GTM).
Log in to FastCentrik admin.
In the left menu, go to Integrations (Propojení).
Find the Google Tag Manager section and click Show settings.
Paste your GTM Container ID into the field.
Save the changes.
❗ After saving, test in Tanganica to confirm the Pixel is working correctly.
Troubleshooting if Pixel is not detected:
Check that all changes were saved and published.
Verify the code has no typos or invalid characters.
Make sure your store pages are fully functional.
