Server-side > WordPress tracking plugins
No impact on page speed
Tracking plugins add 100+ KB of JS to every page. DataNostro runs outside WordPress, you only load the GTM bootstrap (~6 KB). Your Core Web Vitals stay clean.
No plugin conflicts
WP tracking plugins often step on each other's dataLayer. DataNostro's standard GA4 e-commerce dataLayer format = compatibility with any combination of plugins.
Sklik and Heureka for CZ stores
WooCommerce has no native Sklik or Heureka — they're handled by 3rd-party plugins with their own bugs. DataNostro has it built in as a platform.
Stripe / WooPayments fanout
Stripe webhook → DataNostro → GA4 + Meta + Ads + Klaviyo. No plugin, no cron on the WP server, no race conditions with order_id.
Three steps and the data flows.
-
1
Generate the GTM container
Setup Assistant detects WooCommerce and generates a JSON container with purchase, add_to_cart, view_item, begin_checkout events.
-
2
Import into GTM
In GTM → Admin → Import Container → select the JSON. Then paste the GTM web container ID into WordPress (Site Kit by Google or the GTM4WP plugin — at least one integration).
-
3
Tracking subdomain
In GTM → Server container → send tags to your DataNostro subdomain. CNAME, SSL — automatic.

Frequently asked questions
What is server-side tracking for WooCommerce and how does it work? +
Server-side tracking (or server-side tagging) for WooCommerce means conversion events — purchase, add_to_cart, begin_checkout — are sent from your server through a server-side GTM container instead of the browser. DataNostro runs on its own subdomain outside WordPress, so events bypass ad blockers and Safari ITP, don't hurt Core Web Vitals, and arrive complete in GA4, Google Ads, Meta CAPI, Sklik and Heureka. No extra tracking plugin in WordPress.
Is it a WordPress plugin for server-side tracking? +
No — and that's the point. Classic WordPress tracking plugins run client-side and add 100+ KB of JS to every page. DataNostro server-side runs outside WordPress: you just add the GTM container ID via Site Kit or GTM4WP, and events then flow through our server-side container on your subdomain. No heavy plugin, no dataLayer conflicts, no impact on site speed.
Do I need a special WooCommerce plugin? +
No. You just need the GTM container ID in Site Kit or GTM4WP. We send events through server-side GTM, not through the WordPress backend.
Does it work with subscriptions / memberships? +
Yes. WooCommerce Subscriptions, Memberships, and Bookings all fire standard WC actions that GTM4WP captures and propagates into our dataLayer.
What about Polylang / WPML? +
We support multi-language events. We send a language parameter in every event — filter your GA4 reports by it.
WooPayments vs. Stripe — which one? +
We support both. WooPayments uses Stripe under the hood — we catch both webhooks and route them to the platforms with deduplication.
